The Private Healthcare Facilities Ordinance (the Ordinance) (Cap. 633), which was gazetted on 30 November 2018, introduced a new regulatory regime for private healthcare facilities (PHFs) in Hong Kong. Under the Ordinance, all PHFs where registered medical practitioners and/or registered dentists practise must obtain a licence or a letter of exemption. The Government has been implementing the Ordinance in phases based on the risk level of various types of PHFs. Application for clinic licence and request for letter of exemption for small practice clinic will start on 13 October 2025.
