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

Location and specialty options come from the full directory; matching doctors are counted below. Clear the ZIP field to broaden the search, or choose Any procedure in More filters to remove that filter.

Procedure records cover Original Medicare and Medicare Advantage patients. Exact counts may be withheld for privacy or unavailable; missing activity does not mean no experience.
