This paper surveys public-private interfaces within the health insurance market in Brazil, seeking to question the relationships of autonomy and dependence between the supplementary health care enterprises and SUS, as well as some aspects conditioning government regulation. The analysis of this market is referenced on the related literature and on information provided by official sources, consulting businesses, health plans and insurances enterprises and their owners' accounts. One suggests the need for broadening the agenda on the public-private mosaic structuring the Brazilian health system.
