It sounds to me like the closest thing is 11- Office: Location, other than a hospital, skilled nursing facility (SNF), military treatment facility, community health center, State or local public health clinic, or intermediate care facility (ICF), where the health professional routinely provides health examinations, diagnosis, and treatment of illness or injury on an ambulatory basis.

How are you licensed? If you don't agree that 11 is appropriate, then knowing how you are licensed will help solve the puzzle.
