Healthcare is one of the fundamental human rights. Croatian helathcare system is organized as a public service in three levels: primary, secondary and tertiary. The basic regulation that governs the issue of healthcare, and thus the establishment of private practice offices, which is the subject of this paper, is the Health Care Act adopted in 2018, which is still in force, and has undergone four changes since today. This paper presents the procedure for establishing private practice offices. In the beginning, the Croatian health care system as a public service and the legal framework is presented, followed by a presentation of primary health care. The paper focuses on the procedure for establishing practices in the City of Zagreb in fouru areas – family medicine, pediatrics, gynaecology and dental medicine. In the last chapter, the supervision of private health care practices is presented. The surgeries are a novelty that is governed by the Health Care Act from 2018, and it replaces the previous provision of health care under lease or concession. The establishment and opening of a private practice office is carried out through a prescribed procedure that requires the healthcare worker to collect certain documentation that he is obliged to submit with the application, and not on the basis of the decision issued by the Ministry of Health approving the conduct of private practice in the office. Practises in the sense of Health Care Act led to an increase in the number of practices in private practice, which is shown in the paper.
