The Insurance and Private Pension Regulation and Supervision Agency of Türkiye published amendments to the Private Health Insurances Regulation, introducing revised requirements for lifetime renewal guarantees, waiting periods, switching between insurers and policyholder disclosure. The amendments enter into force on 1 January 2026. The framework for the lifetime renewal guarantee (ÖBYG) is standardised across insurers and cannot be changed to the detriment of the insured, with the right defined and monitored via a central system and usable with any insurer once obtained. Eligibility is tied to three years of uninterrupted cover and a claims-to-premium ratio below 80% at the end of that period, and the option is available to policyholders who are not older than 60 at policy inception; insurers must also present the ÖBYG option at the offer stage. Waiting periods are limited to the initial entry period into the system and are no longer applied at renewal (except in cases of interruption), and accrued waiting time is preserved when switching insurers through the central system. Additional measures require timely, complete and accurate information to policyholders on coverage, pricing and other terms that may affect their choices.
