Before you start

A residence or work permit application in progress (the permit is what unlocks SGK and an MHRS-eligible foreigner ID number)
A Yabancı Kimlik Numarası (foreigner ID / YKN), issued with your residence permit — needed for e-Devlet, MHRS and e-Nabız
A Turkish address and phone number (for insurer paperwork, e-Devlet SMS and hospital registration)
Funds for a private health-insurance policy before your first permit appointment (no policy = no permit)

Step-by-step

1
Buy private health insurance (required for your first permit)
Every first-year resident must show a valid private policy at the residence-permit appointment — SGK does not count for the initial permit, and the permit will not be issued or renewed without it. Since April 2025 the policy must meet raised minimums (roughly 15,000 TRY outpatient / 150,000 TRY inpatient cover) and explicitly state it is valid for residence-permit applications. Buy a 'yabancı ikamet' compliant plan from a Turkish insurer (Allianz, Axa, Anadolu, Aksigorta) online or via a broker in minutes.

2
Understand your SGK eligibility (employee = automatic, others = wait 1 year)
If a Turkish company employs you and you hold a work permit, your employer enrolls you in SGK from your first working day — no waiting period — and it also covers your spouse and children under 18. The self-employed pay into SGK via Bağ-Kur. If you are not employed, you can only opt into SGK voluntarily after you have lived in Turkey continuously on a residence permit for one full year; before that, private insurance is your only route.

Choose public vs private hospitals and register (MHRS / e-Nabız)
With SGK you can use state hospitals (devlet hastanesi) and family health centres almost free, plus SGK-contracted private hospitals for a top-up fee. Book public appointments through MHRS (Merkezi Hekim Randevu Sistemi) via mhrs.gov.tr, the MHRS app, or the ALO 182 call centre, and view your records on e-Nabız — both accessed with your foreigner ID through e-Devlet, available in English. For faster, English-speaking care most expats go straight to private hospitals and either pay cash or claim on private insurance.

Know emergencies (112) and pharmacies (eczane)
Dial 112, Turkey's single emergency number, for an ambulance — emergency care (acil) at state hospitals is provided to everyone, including tourists, regardless of insurance. Pharmacies (eczane) are everywhere, pharmacists advise on minor ailments, and many medicines are inexpensive and sold over the counter (a foreign prescription is not legally valid). Outside normal hours, a rotating nöbetçi eczane (on-duty night/weekend pharmacy) is always open — find the nearest one by searching 'nöbetçi eczane' plus your district.

Optional: enroll in SGK once you're eligible
After one year of legal residence (and if not covered through work), you can voluntarily join SGK at your local Social Security office (Sosyal Güvenlik Kurumu / SGK). The monthly premium is set as a percentage of the minimum wage and is modest in hard-currency terms; one premium also covers a spouse and children under 18. Note that new residence-permit applicants are still generally expected to hold private insurance for the permit, so many residents keep a private policy alongside SGK.

Documents you’ll need

Passport and residence/work permit (or in-progress permit application)
Yabancı Kimlik Numarası (foreigner ID number)
Valid private health-insurance policy marked 'valid for residence-permit applications' (for the permit)
Proof of Turkish address and a Turkish mobile number (for e-Devlet/SGK and hospital registration)

Things most newcomers don’t know

For your FIRST residence permit, SGK does not qualify — you must buy private insurance, even though SGK is the cheaper long-term option.

Since ~2018, new residence-permit applicants must present a private policy (with raised April-2025 coverage minimums) for the permit; SGK is only acceptable later, so newcomers can't skip the private step.

You can only opt into SGK voluntarily after one continuous year of residence — but if a Turkish employer hires you, you're in SGK from day one with no wait.

Employees are auto-enrolled and contributions are payroll-deducted by the employer; the 12-month rule only bites for the non-employed who want to join voluntarily.

Istanbul's private hospitals are genuinely excellent and cheap — the same quality that makes the city a top medical-tourism hub for residents' everyday care.

Turkey has 40+ JCI-accredited facilities (around 29 in Istanbul); groups like Acıbadem, Memorial and the American Hospital are multilingual and treat patients from 160+ countries, with prices far below US/UK private rates.

Public (state) hospitals are nearly free with SGK but come with crowds and a real language barrier — budget for private care or an English-speaking facilitator.

SGK covers almost the whole population and public facilities are heavily used, so waits are long and English is patchy; expats routinely use private hospitals (cash or private insurance) for speed and language.

Common mistakes to avoid

Buying a cheap policy that isn't marked 'valid for residence-permit applications' or misses the April-2025 coverage minimums — the permit office will reject it.
Assuming SGK alone gets you the first permit; it doesn't — you still need a private policy until you're eligible to rely on SGK.
Letting your private policy lapse before a permit renewal — a gap can block the renewal even if you're otherwise compliant.
Trying to fill a foreign prescription as-is — it's not legally valid; you need a Turkish doctor's prescription (though many medicines are sold over the counter cheaply).
