Insurance Claim Denied in Turkey? How to Appeal
Learn how to appeal a denied insurance claim in Turkey through SEDDK, Sigorta Tahkim Komisyonu arbitration, and navigating SGK vs. private Özel Sağlık insurance.
Turkey operates a two-tier insurance system — the public SGK (Sosyal Güvenlik Kurumu) health scheme for employed residents alongside a growing private özel sağlık sigortası market. If your claim has been denied, Turkey's Sigorta Tahkim Komisyonu (STK) offers a free, binding arbitration pathway that is faster and more consumer-friendly than the courts and is specifically designed for exactly this situation.
Why Insurers Deny Claims in Turkey
Turkish policyholders face denial reasons that span both the public and private systems, each with its own regulatory framework.
Private health insurance (özel sağlık): out-of-network or non-covered treatment. Policies operated by Allianz Türkiye, AXA Sigorta, Anadolu Sigorta, and others cover treatment only at contracted hospitals. Claims for non-network care without emergency justification are routinely denied. Similarly, treatments not listed in the policy's covered services schedule are excluded regardless of clinical necessity.
Non-disclosure under Turkish Commercial Code Article 1435. Insurers frequently deny claims citing undisclosed pre-existing conditions. However, Article 1435 of the Turkish Commercial Code limits this remedy to willful and material non-disclosure — innocent non-disclosure of a condition the policyholder was unaware of is not a valid ground for full denial. Minor non-material omissions may result only in proportional reduction of coverage.
Missing prior notification for planned hospitalization. Most tamamlayıcı policies require the insurer to be notified before a planned hospital admission. Failure to notify can trigger denial, but for emergencies the urgency must be documented and can be raised as a defense in any appeal.
SGK catalog and referral system disputes. SGK covers only treatments on the national formulary at contracted facilities. Using a non-designated hospital or skipping the fenzhen jiuyi tiered referral sequence can result in full or partial denial. Administrative appeals through SGK follow a separate path from private insurance disputes.

Compulsory Trafik Sigortası and Kasko motor claims. Road accident disputes, including questions of fault attribution, documentation failures, or damage scope disputes, are common in both compulsory MTPL and optional comprehensive motor policies.
How to Appeal a Denied Claim in Turkey
Step 1: Submit a Formal Written Complaint to the Insurer
Contact your insurer's complaints unit (şikayet birimi) in writing. Request the full denial reason citing the specific policy clause. Under SEDDK regulations, insurers must acknowledge within five business days and respond substantively within 15 working days. Document your submission with a delivery timestamp.
Step 2: File a Regulatory Complaint with SEDDK
If the insurer's response is inadequate or regulatory obligations were violated, file a complaint with SEDDK (the Insurance and Private Pension Regulation and Supervision Agency) at seddk.gov.tr (444 7 734). SEDDK investigates market conduct and can impose sanctions on licensed insurers. This step can run concurrently with the STK arbitration process.
Step 3: File an Application with the Sigorta Tahkim Komisyonu (STK)
The STK is Turkey's independent insurance arbitration body. It is funded by insurer contributions and operates entirely separately from the courts. Participation is mandatory for all SEDDK-licensed insurers. File online at sigortatahkim.org.tr — free for small claims, with modest fees for larger disputes. The process is conducted in Turkish. An arbitrator (hakem) is assigned, and decisions are typically issued within 90 to 180 days. STK decisions are final and binding with the same legal force as court judgments.
Step 4: Appeal to the Üst Tahkim Kurumu (for eligible cases)
For cases meeting the value threshold, the Higher Arbitration Panel (Üst Tahkim Kurumu) provides a second-tier review. This appeal must be filed within 10 days of the STK decision.
Step 5: Civil Court as a Final Option
For disputes outside STK jurisdiction, or after all arbitration options are exhausted, the Asliye Ticaret Mahkemesi (Commercial Court of First Instance) handles insurance contract disputes under standard civil procedure.
