Unimed Health Insurance Service

Unimed is the largest healthcare cooperative system in the world and the largest medical network in Brazil. It was founded in 1967 in Santos, São Paulo, by Dr. Edmundo Castilho. Unlike centralized corporations, Unimed operates as a federation of medical cooperatives, allowing local physicians to manage their own regional units while staying under a unified national brand.

The specific document shown represents an online request protocol from Unimed Leste Paulista, a regional branch of the system. This cooperative model ensures that services are adapted to local needs while maintained by the administrative structure of the Unimed National Confederation. The brand is strictly Brazilian in origin and operations, representing a unique model of cooperative private healthcare.
