The aim of this study is to identify the legal characteristics of contracts for the health care services provided by a public payer, i.e. the National Health Fund (NFZ) as part of treatment covered by universal health insurance, as compared to those provided by the health care providers with public or private legal status. This issue is discussed in relation to the legal conditions for the treatment of patients on a commercial basis in those institutions (private or public) which have contracts for the provision of healthcare services under the general health insurance (so-called contracts). The discussion is presented based on author’s own observations, resulting both from his scientific studies in the field of medical law and his work in various entities operating in the health care system.
