Exact listed ZIP, not distance. State, city and specialty match the same source practice; current offices and appointments still need confirmation.

CMS-reported procedure activity spans the doctor’s locations and Medicare patients. It does not establish quality or that this service is offered at the listed office.

How to read these results
