Starfleet Medical

Starfleet Medical was a department of Starfleet that was dedicated to medical research and treatment of Starfleet crew. Based out of San Francisco on Earth, Starfleet Medical oversaw all Starfleet medical personnel and facilities.

In the 23rd century, an office existed known as the Starfleet Surgeon General which held some command authority over Starfleet Medical, including the power to relieve starship medical officers for incompetence. 

Lyran Starfleet
While the Lyran Starfleet also maintained a similar medical service to that of its counterpart, due to the Lyrans' distrust of each other for medical matters, most non-Lyrans in the Lyran Starfleet served in Starfleet Medical. As such, it employed the counselors, the doctors and the medical technicians.
