SGK Health Claim Denied in Turkey: How to Appeal

SGK (Sosyal Güvenlik Kurumu) — Turkey's Social Security Institution — is the backbone of the country's universal health coverage. When SGK denies a claim, refuses to reimburse a treatment, or excludes a medication from coverage, millions of Turkish citizens are left to navigate a bureaucratic appeal process. This guide explains that process step by step.

What SGK Covers

SGK provides health coverage to nearly all Turkish residents through formal employment, voluntary participation, and government-funded programs for low-income individuals (Yeşil Kart and its successors under the General Health Insurance/Genel Sağlık Sigortası scheme).

Covered services include:

• Inpatient hospital care at contracted hospitals
• Outpatient consultations at contracted facilities
• Laboratory tests, imaging, and diagnostics
• Surgical procedures
• Medications on the SGK reimbursable drug list (Geri Ödeme Listesi)
• Maternity care and pediatric services
• Mental health services at contracted facilities
• Physical therapy and rehabilitation

Common SGK Denial Reasons

Understanding why SGK denied your claim is the first step to appealing it effectively.

Treatment at a non-contracted hospital — SGK reimburses care only at hospitals that have signed contracts with SGK (Anlaşmalı Hastane). If you received elective care at a private hospital without an SGK contract, the claim will be denied. Exceptions apply to genuine emergencies — if you were treated at an SGK non-contracted hospital due to an emergency, documentation of the emergency is critical.

Referral system not followed — SGK requires patients to access care through a graduated system: first a family physician (Aile Hekimi), then a specialist if referred, then a tertiary hospital if needed. Bypassing this system (going directly to a specialist without a referral) can result in denial or reduced reimbursement.

Drug not on the reimbursable list — SGK covers only medications on its official reimbursable drug list. Prescriptions for drugs not on the list, or for off-label uses of listed drugs, will be denied.

Medical necessity not established — SGK's reviewing physicians (Sosyal Güvenlik Kurumu Sağlık Kurulu) may determine that a procedure or medication is not medically necessary for the diagnosed condition, or that a less expensive alternative exists that SGK considers equivalent.

Documentation incomplete — Diagnosis codes, physician notes, or itemized billing documentation missing from the submitted claim.

SGK coverage not active — Gaps in premium payments, employer failure to register an employee, or delays in registration can result in a period of inactive SGK coverage during which claims are denied.

Step 1: Contact ALO 170

ALO 170 is SGK's free public assistance and complaint hotline. It is the starting point for any SGK dispute and is available in Turkish. Call ALO 170 to:

• Confirm the specific reason for your denial
• Request information about the appeals process
• Report administrative errors (e.g., an employer who failed to properly register you)
• Log a formal complaint that creates a record in SGK's system

Always write down the call reference number provided by the ALO 170 operator.

Step 2: Obtain Written Denial Documentation

Before filing any formal appeal, request the full written denial decision from SGK. The decision should specify:

• The legal or regulatory basis for the denial (which SGK regulation, which provision of the reimbursable drug list, etc.)
• The specific diagnosis, treatment, or medication denied
• The date of the denial and the review period

If the denial was communicated verbally or through a simple system notification, request the formal written decision from your local SGK provincial directorate (İl Müdürlüğü).

Step 3: Administrative Objection (İtiraz)

The formal internal appeal within the SGK system is the administrative objection (itiraz). This is a written challenge to the denial, filed with the relevant SGK authority.

Where to file: The SGK provincial directorate (İl Müdürlüğü) in your province, or the SGK district office (İlçe Müdürlüğü) for local matters.

Time limit: You must file the itiraz within 60 days of the date of the denial decision. Missing this window forecloses your internal appeal rights.

What to include:

• Your name, Turkish ID number (TC Kimlik No), and SGK registration number
• The denial decision reference number and date
• A clear statement of the grounds for your objection — why the denial is incorrect
• Medical documentation: physician notes, hospital records, diagnosis confirmation, specialist opinions
• For drug denials: physician letter explaining why the specific medication is clinically necessary for your condition

SGK is required to review and issue a written decision on your itiraz. The review process may involve SGK's health board.

Step 4: SGK Health Board Review

For medically complex cases, your case may be referred to (or you can request referral to) the SGK Sağlık Kurulu — the Health Board that reviews clinical coverage disputes. The Health Board consists of physicians and can overturn administrative denials based on medical evidence.

A strong physician opinion letter, ideally from a specialist at a recognized Turkish teaching hospital, is the most effective tool at this stage.

Step 5: Administrative Court (İdare Mahkemesi)

If the internal itiraz process is exhausted without resolution, you can file a case with the Administrative Court (İdare Mahkemesi) in your province. SGK decisions are administrative acts and are reviewable by the administrative judiciary.

Administrative court cases involving SGK:

• Must be filed within a specific timeframe after the final SGK decision (typically 60 days after the final administrative ruling)
• Involve written submissions by both parties
• May take 6–18 months to resolve
• Can result in orders requiring SGK to pay, cover, or reinstate coverage

For significant claims — high-cost surgeries, expensive medications, or long-term treatment denials — the administrative court route is well-established in Turkey and produces favorable outcomes for patients with strong documentation.

Tips for Success

• Speed matters. SGK deadlines for appeals are strict. File your itiraz promptly after receiving the denial.
• Documentation is decisive. SGK health board reviewers respond to medical evidence. Get your physician to write a targeted letter.
• Keep copies of everything. Every document you submit to SGK should be copied and retained, along with proof of submission (postal receipts, delivery confirmation, or office stamps).
• Know your coverage status. Verify your SGK registration and premium payment status before appealing — some denials stem from administrative errors in registration that are easily corrected.
