Complications or Medical Malpractice? How Turkish Courts Distinguish the Two

One of the most common defences raised after a medical injury in Turkey is:

“This was a complication, not medical malpractice.”

A foreign patient may hear this statement immediately after something goes wrong.

A surgeon may say that nerve damage is a known complication.

A clinic may explain that infection is always possible after surgery.

A dental provider may say that implant failure can happen even when treatment is performed correctly.

A cosmetic surgeon may argue that asymmetry or scarring is simply an accepted surgical risk.

Sometimes that explanation is legally correct.

A patient can suffer serious harm even though the doctor and hospital complied fully with accepted medical standards.

Medicine involves uncertainty, and healthcare professionals do not ordinarily guarantee that every therapeutic treatment will succeed.

But the word “complication” is not a complete legal defence by itself.

Turkish courts generally ask much more.

Was the adverse event genuinely a recognised medical complication?

Was the original procedure correctly indicated?

Was it performed according to accepted medical standards?

Were reasonable precautions taken to reduce the risk?

Was the patient properly informed about the relevant complication before treatment?

Was the complication recognised promptly?

Was it managed appropriately after it occurred?

Did a delay or other medical failure make the damage more serious?

Is there a causal connection between the alleged failure and the patient’s final injury?

And, in purely aesthetic procedures, did the provider fulfil the separately promised result-oriented contractual obligation?

These questions explain why two patients who suffer the same medical complication may receive completely different legal outcomes.

In one case, a complication may occur despite impeccable medical treatment, proper informed consent and prompt management. There may be no malpractice liability.

In another case, the original complication may have been unavoidable, but delayed recognition or poor treatment may convert the subsequent damage into a compensable malpractice claim.

A third case may involve no technical medical error at all, yet liability may still arise because the patient was not adequately informed of the relevant risk.

Recent Turkish Court of Cassation decisions illustrate all three possibilities.

In Yargıtay 3rd Civil Chamber, E. 2025/6156, K. 2026/2829, dated 6 May 2026, the Court accepted that a bowel injury arising after surgery was a foreseeable complication, that the medical treatment and complication management were appropriate and that there was no sufficient causal connection between the alleged shortcomings and the claimed loss. The compensation claim therefore failed.

By contrast, in Yargıtay 3rd Civil Chamber, E. 2026/87, K. 2026/3186, dated 20 May 2026, expert reports found no technical medical malpractice, yet compensation was upheld because the informed-consent documentation was inadequate and the defendants could not prove that the patient had been properly informed orally about the procedure and risks.

And in aesthetic surgery, the Court of Cassation has taken an additional approach. In Yargıtay 6th Civil Chamber, E. 2024/1507, K. 2025/1137, dated 19 March 2025, the Court held that simply characterising postoperative scarring and asymmetry as complications was insufficient because the aesthetic procedure was legally treated as a result-oriented contract for work. The promised aesthetic result also had to be examined.

For foreign patients who received treatment in Turkey, understanding this distinction is essential before accepting a clinic’s statement that:

“Nothing can be done because it was a complication.”

What Is a Medical Complication?

In medical terms, a complication is generally an adverse event that can occur during or after a medical procedure even where proper professional care has been exercised.

Examples can include:

• postoperative infection;
• bleeding;
• thrombosis;
• nerve injury;
• organ perforation;
• wound-healing problems;
• implant failure;
• scarring;
• anaesthesia-related adverse events.

The fact that an event appears in medical literature as a recognised complication is relevant.

However, recognition in medical literature does not automatically resolve legal responsibility.

A court normally needs to know not only what happened, but also how and why it happened.

The same bowel perforation, for example, could arise:

• despite technically appropriate surgery;
• because of negligent surgical technique;
• or as an unavoidable complication that later became catastrophic because the hospital failed to recognise it promptly.

Those scenarios are legally different.

What Is Medical Malpractice?

Medical malpractice generally involves a legally relevant failure by a healthcare professional or healthcare institution to comply with the required standard of medical, professional, contractual or organisational care.

It can arise from an affirmative error or from failing to do something necessary.

Examples include:

• incorrect diagnosis;
• unreasonable diagnostic delay;
• inappropriate treatment selection;
• operating without proper indication;
• technical surgical error;
• failure to order necessary tests;
• negligent postoperative monitoring;
• failure to recognise deterioration;
• delayed treatment of a complication;
• inadequate hospital organisation;
• failure to obtain valid informed consent.

The key difference is therefore not simply:

complication = no fault

versus

malpractice = bad result.

The real distinction is whether the injury occurred despite appropriate care or because a legally required standard was breached.

Turkish Courts Usually Examine the Entire Treatment Process

A medical malpractice case should not be reduced to one moment inside the operating room.

Turkish courts may examine:

1. the decision to perform the intervention;
2. preoperative assessment;
3. information given to the patient;
4. technical performance of the intervention;
5. postoperative monitoring;
6. recognition of complications;
7. treatment of complications;
8. causal connection with the final injury.

This means that an operation can be technically correct while the overall medical care remains legally defective.

For example:

A surgical complication develops without negligence.

The patient repeatedly reports severe pain and fever.

The hospital fails to investigate for twelve hours.

The patient’s condition deteriorates.

Emergency surgery eventually becomes necessary and permanent organ damage results.

The initial complication may have been unavoidable.

The delayed management may not have been.

That distinction is frequently central to malpractice litigation.

First Test: Was the Medical Procedure Properly Indicated?

Before analysing the complication itself, experts may ask whether the medical intervention should have been performed at all.

A known complication is not necessarily an acceptable defence where:

• the procedure was medically unnecessary;
• the patient was not an appropriate candidate;
• contraindications were ignored;
• safer alternatives were available and not considered where the applicable standard required consideration.

Suppose a doctor performs a high-risk elective procedure on a patient with clear contraindications.

A recognised complication then occurs.

The healthcare provider cannot necessarily defend the case simply by proving that the event was listed as a possible complication.

The original treatment decision may itself have been negligent.

Second Test: Was the Procedure Performed According to Accepted Medical Standards?

This is usually an expert medical question.

Courts rely heavily on:

• medical records;
• operative reports;
• radiological images;
• laboratory findings;
• specialist expert reports;
• Adli Tıp Kurumu assessments;
• other court-appointed expert panels.

The expert analysis should determine whether the doctor used medically acceptable technique and appropriate professional care.

The 2026 Court of Cassation decision concerning postoperative bowel injury provides a useful example.

Expert evidence established that the operation was performed according to medical technique and that the bowel injury was a foreseeable complication. The Court also relied on findings that complication management was appropriate and that certain alleged losses lacked the required causal link. On those facts, liability was rejected.

The decision demonstrates that a properly established complication can defeat a malpractice claim where:

medical technique was appropriate + complication management was appropriate + causation for the alleged damage was not established.

Another 2026 Example: Complication Without Professional Fault

In Yargıtay 3rd Civil Chamber, E. 2025/1657, K. 2026/257, the Court reviewed claims arising following caesarean delivery and subsequent abdominal complications.

The medical expert reports concluded that the relevant conditions could occur despite appropriate care and that there was no negligence, lack of care or improper medical practice in diagnosis, follow-up and treatment.

The Court upheld dismissal of the claim.

This decision reinforces an important principle:

The existence of serious injury alone is not sufficient.

The patient must establish a legally relevant deficiency in care and, where required, the causal connection between that deficiency and the damage claimed.

Third Test: Was the Complication Managed Correctly?

This is perhaps the most misunderstood part of the distinction.

A complication can initially be unavoidable but subsequently be managed negligently.

When Turkish courts and medical experts examine complication management, relevant questions may include:

• When did the first warning signs appear?
• When was the doctor informed?
• Were appropriate tests ordered?
• Was imaging performed in time?
• Was another specialist consulted?
• Was the patient transferred where necessary?
• Was emergency revision surgery performed promptly?
• Were vital signs monitored adequately?

A provider cannot necessarily rely on the defence:

“Perforation is a known risk of the operation.”

if the real allegation is:

“You failed to recognise and treat the perforation for twenty-four hours.”

The first statement concerns the occurrence of the complication.

The second concerns its management.

They are legally distinct.

A Complication Can Become a Malpractice Case Through Delay

Consider a hypothetical foreign patient undergoing abdominal surgery in Turkey.

At 10:00 a.m. the patient develops severe abdominal pain.

At 12:00 p.m. blood pressure begins falling.

At 2:00 p.m. laboratory results show deterioration.

At 7:00 p.m. the surgeon is finally informed.

At midnight imaging is performed.

At 3:00 a.m. emergency surgery identifies bowel perforation and widespread infection.

The hospital may prove that bowel perforation is a recognised surgical complication.

But that does not answer whether:

the twelve-to-seventeen-hour delay in diagnosis and treatment worsened the injury.

An expert must examine whether a competent healthcare team should have reacted earlier and whether earlier treatment would probably have produced a better outcome.

This is how complication management becomes a causation issue.

Causation Is Essential

Even where a medical shortcoming is identified, the patient must generally establish the required connection between that shortcoming and the damage claimed.

This is one reason the 6 May 2026 Court of Cassation decision is particularly instructive.

The case included allegations concerning early discharge.

However, expert evidence concluded that even if the patient had not been discharged early and the complication had been discovered at that stage, the same treatment would have been required. The Court therefore found the necessary causal connection lacking for the claimed consequences.

This demonstrates that malpractice litigation involves two different questions:

Was something done incorrectly?

and

Did that error cause the damage for which compensation is claimed?

Both can matter.

Informed Consent Is a Completely Separate Question

Perhaps the most important rule for foreign patients is that:

A complication can be medically unavoidable and still create liability if the patient was not properly informed about the risk.

Turkish patient-rights legislation requires patients to receive information about, among other matters:

• the nature of the medical intervention;
• alternatives;
• benefits and risks;
• possible complications;
• consequences of refusing treatment.

The information must be provided in an understandable manner, and except in emergencies, the patient should be given reasonable time to consider it.

This legal obligation exists because a patient has the right to decide whether to accept a medical risk.

The question is not:

“Could the complication occur?”

It is also:

“Did the patient knowingly agree to face that risk?”

A Signature Is Not Necessarily Enough

Foreign patients frequently sign forms immediately before treatment.

A patient may be given:

• a general admission form;
• anaesthesia consent;
• procedure consent;
• personal-data forms;
• payment documents.

The existence of a signature does not automatically prove adequate informed consent.

The form should relate to the actual medical intervention and relevant risks.

The patient should also have been meaningfully informed.

This principle was confirmed in the important 20 May 2026 Court of Cassation decision, E. 2026/87, K. 2026/3186.

The patient suffered serious injury following a thyroid-related radiofrequency ablation procedure.

Medical expert reports found no technical error in the treatment.

Nevertheless, the courts concluded that the informed-consent forms were inadequate for the procedure and that the defendants failed to prove that proper oral information had been provided.

The Court of Cassation upheld the award of material and non-material compensation.

This decision is critical because it demonstrates:

No technical malpractice does not necessarily mean no liability.

Who Must Prove Informed Consent?

Current Turkish case law places significant evidential responsibility on the healthcare defendants in this area.

In the 2026 decision, the Court specifically referred to the defendants’ inability to prove that the patient had been orally informed.

For foreign patients, this issue can become especially important where:

• the consent form was only in Turkish;
• the patient did not speak Turkish;
• no interpreter was provided;
• the form was generic;
• the relevant complication was not identified;
• the patient signed immediately before anaesthesia.

Each factor should be assessed together with the broader evidence.

Language Barriers Matter for Foreign Patients

A patient cannot make an informed medical decision about a risk that he or she does not understand.

Turkey’s Patient Rights Regulation requires medical information to be communicated as clearly as possible and in a way that the patient can understand. It also makes clear that the patient should generally be informed by the healthcare professional responsible for the intervention.

This means that a clinic coordinator saying:

“Everything is fine, just sign here”

should not automatically be treated as equivalent to proper medical information.

International patients should therefore preserve:

• consent documents;
• translations;
• interpreter records;
• WhatsApp communications;
• preoperative consultation records.

What If the Patient Was Properly Warned About the Complication?

Proper warning can substantially strengthen the healthcare provider’s defence, but it does not give the provider unlimited immunity.

Imagine the consent form clearly states:

“Bowel perforation is a recognised risk.”

The patient understands this and accepts the procedure.

A bowel perforation then occurs.

The healthcare provider still needs to establish, where disputed, that:

• the procedure was properly indicated;
• technique was appropriate;
• complication management was appropriate.

Consent to a risk is not consent to negligence.

A patient who knowingly accepts the risk of bleeding does not thereby consent to negligent failure to treat the bleeding.

Consent Does Not Waive the Right to Safe Treatment

This principle should be made very clear.

A patient who signs a consent form does not waive the right to expect professionally competent healthcare.

The patient accepts recognised risks inherent in a properly performed procedure.

The patient does not ordinarily accept:

• negligent surgical technique;
• inadequate monitoring;
• preventable delay;
• defective hospital organisation.

Accordingly:

known complication + valid consent ≠ automatic defence to every allegation.

The quality of medical performance and complication management still matter.

When Does a Complication Clearly Favour the Doctor or Hospital?

A healthcare provider’s defence will generally be strongest where expert evidence establishes the following chain:

1. The procedure was medically appropriate.
2. The patient was an appropriate candidate.
3. The procedure was performed according to accepted standards.
4. The event was a recognised unavoidable or reasonably unavoidable complication.
5. The patient was adequately informed about that material risk.
6. The complication was recognised and treated appropriately.
7. No separate organisational negligence occurred.
8. The alleged additional losses cannot be causally attributed to negligent conduct.

The 2026 Court of Cassation decisions provide examples of cases where medical expert evidence supporting this type of structure resulted in dismissal.

When Does a “Complication” Defence Become Weak?

The defence becomes much weaker where evidence suggests:

• the intervention was unnecessary;
• medical technique departed from accepted standards;
• the risk was never properly disclosed;
• the complication was discovered late;
• treatment was delayed;
• required transfer was not organised;
• hospital systems were inadequate;
• records are missing or contradictory;
• the clinic’s own communications contradict its legal defence.

In such circumstances, the court should investigate the entire medical process rather than accepting the label “complication.”

Cosmetic Surgery Requires a Different Analysis

The distinction becomes even more important in purely aesthetic procedures.

Turkish Court of Cassation jurisprudence frequently characterises result-oriented aesthetic procedures as contracts for work — eser sözleşmesi rather than ordinary therapeutic mandate relationships.

This means that the healthcare provider may have undertaken not merely to exercise medical care but to achieve an agreed aesthetic result.

In Yargıtay 6th Civil Chamber, E. 2024/1507, K. 2025/1137, the patient underwent elective eyelid surgery.

Medical expert evidence regarded postoperative scars and asymmetry as complications that could occur despite appropriate care.

The lower court dismissed the case based on that assessment.

The Court of Cassation disagreed with the legal analysis.

It held that because the treatment was a result-oriented aesthetic intervention, the court also had to analyse the promised outcome under the rules governing contracts for work.

The fact that an adverse aesthetic result could medically be called a complication was therefore not sufficient by itself to defeat the claim.

Why Aesthetic Procedures Are Different

Compare two patients.

Patient A: undergoes emergency surgery to remove a life-threatening tumour.

Patient B: undergoes elective cosmetic eyelid surgery purely to achieve a better appearance.

In the first case, the doctor normally promises professionally appropriate treatment, not a guaranteed cure or perfect result.

In the second, the Court of Cassation may identify an additional result obligation arising from the aesthetic works-contract relationship.

This does not mean every dissatisfied cosmetic patient automatically wins.

The court must still determine:

• what result was promised;
• the patient’s original condition;
• whether the final outcome is objectively defective;
• whether biological factors or patient conduct affect responsibility.

But calling the result a “complication” may not end the case.

Another Aesthetic Example: Treatment Costs Caused by Complications

The Court of Cassation’s approach can also affect damages.

In Yargıtay 6th Civil Chamber decision K. 2025/2009, the Court considered expenses incurred following complications from aesthetic treatment.

It held that the patient’s physical therapy, rehabilitation, psychological treatment and other relevant treatment expenses associated with the resulting condition required proper examination rather than restricting the analysis to a narrow corrective-procedure cost.

For foreign patients, this can be relevant where failed aesthetic treatment in Turkey requires extensive corrective treatment abroad.

What About Dental Aesthetic Treatment?

The same distinction can arise in procedures such as:

• veneers;
• crowns;
• aesthetic implant treatment;
• smile-design procedures.

Where treatment is substantially result-oriented, Turkish courts can examine works-contract principles.

A clinic cannot necessarily answer an objectively defective aesthetic dental result merely by saying:

“Complications can happen.”

The promised result and quality of completed work may also be legally relevant.

What About Hair Transplantation?

Hair transplant cases can also involve overlapping questions.

Possible complications may include:

• infection;
• scarring;
• donor-area damage;
• poor graft survival.

The legal analysis may examine:

• whether the procedure was performed by appropriately authorised healthcare personnel;
• promised graft numbers or technique;
• professional medical performance;
• complication management;
• informed consent;
• agreed aesthetic result.

A patient should therefore avoid treating “poor growth” and “medical malpractice” as automatically identical.

Objective medical and contractual evidence is required.

Medical Tourism Patients Have an Additional Regulatory Framework

Foreign patients receiving treatment under international health tourism are also covered by Turkey’s updated International Health Tourism and Tourist Health Regulation, effective from 26 April 2025.

The Regulation requires healthcare facilities performing surgical and interventional procedures in an operating-room setting within international health tourism to maintain complication insurance.

This is particularly important for foreign patients undergoing:

• cosmetic surgery;
• bariatric surgery;
• other qualifying surgical or interventional treatment.

However, complication insurance should not be confused with malpractice liability.

The existence of insurance does not automatically prove negligence.

Likewise, a complication being covered by insurance does not necessarily mean the patient has no separate malpractice claim.

The policy, event and legal responsibility must be analysed individually.

Why Complication Insurance Matters

Suppose a foreign patient suffers a recognised postoperative complication.

There is no negligence.

But the complication requires substantial additional treatment.

The compulsory complication-insurance framework may become relevant even though malpractice liability is difficult to establish.

In another case, the same complication may have been negligently managed.

The patient may then need to examine both:

• potential insurance coverage;
• malpractice compensation.

These are distinct legal questions.

The Role of Medical Records

The distinction between complication and malpractice is usually impossible to analyse properly without the medical file.

Important records can include:

• preoperative assessment;
• operative report;
• anaesthesia records;
• nursing observations;
• vital-sign charts;
• laboratory results;
• radiological images;
• consultation records;
• medication charts;
• discharge documentation;
• consent forms.

These records allow experts to reconstruct exactly what occurred.

A hospital saying:

“It was a complication”

should be able to support that statement with medical evidence.

A Timeline Can Be Decisive

Foreign patients should create a chronology.

For example:

Day 1 — surgery performed.

Day 2 — severe pain begins.

Day 2, 14:00 — patient informs nurse.

Day 2, 18:00 — fever develops.

Day 3, 02:00 — surgeon contacted.

Day 3, 09:00 — CT ordered.

Day 3, 13:00 — perforation identified.

Day 3, 16:00 — revision surgery.

The medical expert can then determine whether complication management complied with accepted standards.

Without chronology, both patient and provider may simply argue about labels.

WhatsApp Messages Can Be Important

Medical tourism providers frequently communicate postoperatively through WhatsApp.

Messages can become extremely important where the patient reports symptoms after leaving the hospital.

For example:

Patient: “I have a fever of 39°C.”

Clinic: “This is normal.”

Patient: “I cannot breathe properly.”

Clinic: “Wait until tomorrow.”

If later expert evidence establishes that these were warning signs requiring emergency assessment, the messages may help prove delayed complication management.

Patients should preserve complete conversations rather than isolated screenshots wherever possible.

A Foreign Doctor’s Report Can Challenge the “Complication” Defence

After returning home, a foreign patient may receive a second opinion.

A specialist may conclude:

“This is not an unavoidable surgical complication. The implant was incorrectly positioned.”

Or:

“The complication itself was recognised, but treatment was delayed and the delay caused permanent injury.”

Such a report can be valuable in preparing the Turkish case.

The Turkish court will still evaluate the evidence according to Turkish procedural rules and may obtain its own expert report.

But foreign medical evidence can help identify the precise allegation and challenge an overly general complication defence.

Expert Reports Must Answer the Correct Question

An inadequate expert report may say only:

“This event is a known complication.”

That may not be enough.

A proper malpractice assessment should generally address:

1. Was the procedure indicated?
2. Was medical technique correct?
3. Was the event a recognised complication?
4. Was it preventable?
5. Was informed consent adequate?
6. Was the complication detected promptly?
7. Was management appropriate?
8. Did any delay worsen the damage?
9. Is there causation between the alleged deficiency and final injury?

If the expert report does not answer these questions where they are genuinely disputed, legal objections may be necessary.

The Patient’s Own Conduct Can Also Matter

Complication management sometimes depends on the patient returning for follow-up.

For example:

A patient develops symptoms but refuses medical review.

Or leaves Turkey against medical advice.

Or fails to follow critical postoperative instructions.

These facts can affect causation and responsibility.

The 2025 aesthetic eyelid decision noted that the patient had not returned to the treating physician after surgery, meaning the physician did not have an opportunity to manage the complication. Nevertheless, because the procedure was a result-oriented aesthetic contract, the Court still held that the broader contractual result required examination.

This demonstrates that patient conduct matters but does not always automatically eliminate every claim.

Can a Complication Case Still Produce Moral Damages?

Potentially, if another legally actionable violation exists.

The clearest modern example is inadequate informed consent.

In the 20 May 2026 Court of Cassation case, there was no technical medical error, yet the lack of adequately proven informed consent resulted in compensation liability.

Therefore:

“No technical malpractice” does not always equal “no compensation.”

The legal basis of the claim matters.

Who Bears the Burden of Proof?

The burden of proof depends on the particular disputed issue.

As a general principle, the patient alleging malpractice must provide a legal and evidential basis for the claim, and expert medical evidence plays a central role in establishing professional fault and causation.

But informed consent is different.

Current Constitutional Court and Court of Cassation jurisprudence places the burden of proving adequate informed consent on the relevant healthcare defendants.

The 2026 Court of Cassation decision is a strong recent example: the defendants could not prove adequate oral information and compensation was upheld despite the absence of technical malpractice.

Practical Decision Tree: Complication or Malpractice?

Foreign patients can use the following questions as an initial framework.

Question 1: Is the event a medically recognised complication?

If no, malpractice suspicion increases.

If yes, continue.

Question 2: Was the operation performed correctly?

If no, there may be medical malpractice.

If yes, continue.

Question 3: Was the patient informed about this material risk?

If no, informed-consent liability may arise.

If yes, continue.

Question 4: Was the complication recognised promptly?

If no, malpractice may arise from delayed diagnosis.

If yes, continue.

Question 5: Was the complication managed appropriately?

If no, malpractice may arise from poor complication management.

If yes, continue.

Question 6: Did a hospital organisational failure worsen the outcome?

If yes, hospital liability may arise.

Question 7: Was the procedure purely aesthetic and result-oriented?

If yes, the promised result must also be examined under the Court of Cassation’s works-contract approach.

Only after answering these questions can a reliable legal distinction normally be made.

Example 1: Genuine Complication, No Liability

A patient undergoes medically indicated surgery.

The procedure is performed correctly.

The patient had been informed about a recognised bleeding risk.

Bleeding occurs.

The hospital detects it quickly and performs emergency treatment.

The patient unfortunately requires additional recovery time but no additional injury was caused by negligent conduct.

This is the strongest example of a genuine complication without malpractice.

Example 2: Complication Plus Negligent Management

A recognised postoperative leak occurs.

The patient repeatedly reports severe symptoms.

The hospital ignores warning signs for two days.

Sepsis develops and permanent organ damage follows.

The original leak may be a complication.

The resulting severe injury may still involve malpractice because of negligent complication management.

Example 3: No Technical Error but No Informed Consent

A known nerve injury occurs despite technically proper treatment.

The patient was never informed of the risk and the provider cannot prove adequate information.

This can create liability even without technical malpractice, as confirmed by the Court of Cassation’s May 2026 informed-consent judgment.

Example 4: Cosmetic Complication and Failed Promised Result

A patient undergoes elective aesthetic eyelid surgery.

Postoperative asymmetry and scarring arise.

Experts classify those outcomes as possible complications.

However, the aesthetic result promised by the provider was not achieved.

Turkish Court of Cassation jurisprudence requires the works-contract result obligation to be examined separately from the complication label.

Example 5: No Causation

A minor delay occurs in postoperative care.

However, medical experts conclude that the same treatment and final result would have occurred even without the delay.

Even if the hospital process was imperfect, the compensation claim may fail where the necessary causal connection to the alleged damage cannot be established.

The 6 May 2026 Court of Cassation decision illustrates the importance of this causation analysis.

What Should a Foreign Patient Do After Being Told “It Was Just a Complication”?

Do not immediately assume the clinic is correct.

But do not automatically assume malpractice either.

Instead:

1. Request the complete medical record.
2. Obtain the operative report.
3. Obtain all consent forms.
4. Request anaesthesia records.
5. Obtain radiological images and laboratory results.
6. Preserve WhatsApp communications.
7. Create a symptom timeline.
8. Obtain an independent specialist assessment.
9. Identify whether the procedure was therapeutic or purely aesthetic.
10. Have Turkish legal counsel analyse medical fault, consent, causation and limitation periods separately.

The word “complication” should be the beginning of the legal analysis, not the end.

Frequently Asked Questions

What is the difference between a complication and medical malpractice in Turkey?

A complication can occur despite appropriate medical care. Medical malpractice involves a legally relevant breach of the required medical, professional or organisational standard.

Does a known complication mean the doctor cannot be sued?

No. Courts may still examine whether the procedure was properly performed, whether the patient was informed and whether the complication was appropriately managed.

Can a doctor be liable for failing to treat a complication?

Yes, potentially. Even an unavoidable complication can lead to liability where it is negligently recognised or managed.

What if the complication was listed in the consent form?

That strengthens the informed-consent defence, but it does not excuse negligent medical treatment or negligent complication management.

What if the surgery was technically correct?

There may still be liability where informed consent was inadequate. The Court of Cassation confirmed this in E. 2026/87, K. 2026/3186.

Can a Turkish hospital be liable even if the surgeon made no mistake?

Potentially, where hospital organisation, monitoring, transfer, emergency response or other institutional systems were deficient.

Does infection automatically mean malpractice?

No. Infection can be a recognised complication. The legal question is whether proper preventive, diagnostic and treatment standards were followed.

Does bowel perforation automatically mean malpractice?

No. Turkish Court of Cassation decisions recognise that bowel injury can in appropriate circumstances be a foreseeable complication where medical technique and subsequent management were appropriate.

What if the hospital discharged me too early?

The legal question includes causation. If earlier inpatient detection would probably have changed the outcome, early discharge may become significant. If expert evidence establishes that the same treatment and outcome would have occurred, liability may not arise.

Are cosmetic surgery complications treated differently?

Potentially, yes. Result-oriented aesthetic interventions can be treated as contracts for work. The Court may therefore examine whether the promised aesthetic result was achieved even where an adverse result is medically characterised as a complication.

Can I claim compensation if I was never warned about the complication?

Potentially. Turkish law requires patients to be informed about possible complications, and recent Court of Cassation authority confirms that inadequate informed consent can create liability even without technical malpractice.

Who must prove that I was informed?

Current case law places the burden of proving adequate informed consent on the relevant healthcare defendants.

Does a Turkish-language consent form protect the hospital against a foreign patient?

Not automatically. The information must be communicated in a way the patient can understand.

Do foreign medical tourists have complication insurance protection?

Turkey’s 2025 International Health Tourism Regulation requires healthcare facilities to maintain complication insurance for international health-tourism surgical and interventional procedures performed in operating-room settings. Coverage and entitlement still depend on the policy and circumstances.

Does complication insurance mean malpractice occurred?

No. Insurance coverage and malpractice liability are separate issues.

What evidence is most important?

Medical records, operative reports, postoperative records, consent forms, radiological images, WhatsApp communications and independent specialist reports can all be important.

Conclusion: “Complication” Is a Medical Description, Not an Automatic Legal Defence

The most important lesson for foreign patients is that Turkish law does not treat the word “complication” as a magic phrase that automatically eliminates medical liability.

A complication may indeed occur despite flawless treatment.

Where:

the procedure was correctly indicated,

medical technique was appropriate,

the patient was adequately informed,

the complication was recognised promptly,

management complied with medical standards,

and

no negligent conduct caused additional damage,

the healthcare provider may have a strong defence.

Recent Court of Cassation decisions confirm this.

In E. 2025/6156, K. 2026/2829, the Court relied on expert findings showing that the surgical event was a foreseeable complication, treatment was appropriate and the alleged deficiencies did not have the necessary causal relationship with the claimed loss. Liability was rejected.

Similarly, in E. 2025/1657, K. 2026/257, medical expert findings supported the conclusion that the patient’s adverse condition was a complication that could arise despite proper care and that no relevant negligence or lack of professional care had been established. The dismissal was upheld.

But those decisions represent only one side of the legal distinction.

The Court of Cassation’s 20 May 2026 informed-consent judgment demonstrates the opposite possibility.

There, experts found no technical medical error.

Nevertheless, compensation remained payable because the consent documentation was inadequate and the relevant defendants could not prove that the patient had been properly informed.

The legal lesson is significant:

A medically unavoidable complication does not automatically cure an informed-consent violation.

Patient-rights legislation expressly requires information concerning possible complications and requires the information to be presented in a manner the patient can understand.

For foreign patients, this means language barriers must be taken seriously.

A patient who cannot understand Turkish cannot necessarily be treated as adequately informed merely because a Turkish-language form contains a signature.

A second major exception concerns complication management.

A healthcare provider may not be responsible for causing the original complication but may be responsible for failing to recognise or treat it properly.

The central chronology becomes critical:

When did symptoms appear?

When was the healthcare team informed?

When were tests performed?

When was the complication diagnosed?

When was corrective treatment provided?

A delay can transform an otherwise unavoidable complication into a malpractice dispute where expert evidence establishes that earlier action would probably have prevented or reduced the final injury.

Causation remains essential.

An imperfect hospital process does not automatically justify compensation if medical evidence establishes that the final injury would have occurred regardless.

This is why Turkish malpractice litigation frequently turns on expert analysis rather than labels.

The expert should not merely write:

“This was a complication.”

A useful assessment should explain:

why it was a complication,

whether it was avoidable,

whether treatment met professional standards,

whether management was timely,

and

whether any identified failure caused additional damage.

Aesthetic procedures introduce an additional legal dimension.

The Court of Cassation’s 19 March 2025 aesthetic eyelid decision demonstrates that in result-oriented cosmetic treatment, simply identifying postoperative asymmetry or scarring as a recognised complication may not be sufficient.

Because the relationship can constitute a contract for work, the court must also examine the promised aesthetic result.

The Court expressly found it incorrect to rely only on an expert report stating that the result could occur as a complication without analysing whether the agreed contractual result had been delivered.

This distinction is highly relevant to foreign patients travelling to Turkey for:

rhinoplasty,

breast surgery,

facelift procedures,

eyelid surgery,

aesthetic dental treatment,

and other result-oriented interventions.

Foreign medical tourists also benefit from a new regulatory development.

Turkey’s International Health Tourism and Tourist Health Regulation, effective from 26 April 2025, requires complication insurance for qualifying surgical and interventional procedures carried out in operating-room settings for international health tourists.

This does not replace malpractice law.

It creates an additional issue that should be checked where a complication leads to further medical treatment or expense.

Accordingly, when a Turkish doctor, hospital or clinic tells a foreign patient:

“It was only a complication, so we are not responsible,”

the appropriate legal response is not automatically to reject or accept that statement.

The correct questions are:

Was it genuinely an unavoidable complication?

Was the treatment technically appropriate?

Was I properly informed about this specific risk?

Did the hospital recognise the complication in time?

Was it managed properly?

Did a delay make my injury worse?

Was the procedure purely aesthetic and was a particular result promised?

What do the medical records and independent experts show?

Only after these questions are answered can the line between complication and medical malpractice be drawn reliably.

Foreign patients should therefore preserve:

• complete medical records;
• consent forms;
• operative reports;
• anaesthesia records;
• postoperative observations;
• laboratory results;
• scans;
• WhatsApp communications;
• photographs;
• corrective-treatment records.

These documents allow a Turkish lawyer and medical expert to reconstruct the treatment process and determine whether the provider’s “complication” explanation is medically and legally sustainable.

If you suffered serious injury after medical treatment in Turkey, do not assume that a hospital’s description of the event as a “known complication” automatically eliminates your right to compensation. Turkish courts distinguish between an unavoidable complication, negligent creation of a complication, negligent management of a complication, inadequate informed consent and—particularly in aesthetic procedures—failure to achieve an agreed result. The legal outcome depends on which of these categories the evidence supports.

Legal Disclaimer

This article provides general information concerning the distinction between medical complications and medical malpractice under Turkish law as of September 2026. It does not constitute individual legal advice.

Whether a medical event constitutes an unavoidable complication or actionable malpractice depends on the treatment, medical standards applicable at the time, informed-consent process, complication management, hospital organisation, expert medical evidence and causal relationship between any identified breach and the patient’s injury.

Aesthetic interventions and international health-tourism procedures can also involve additional contractual and regulatory rules.

Each medical malpractice case should therefore be individually assessed using the complete medical records and appropriate specialist evidence.
