Procedures
From CMS Care Compare, which counts the procedures a clinician billed to
Original Medicare and Medicare Advantage over a recent 12-month period.
CMS reports a fixed list of common procedures, so this is not everything
the clinician does. Counts of 10 or fewer are given as a range, because
CMS withholds small numbers.
Melanoma (skin cancer) excision
1–10 times
Removal of tissue
1–10 times
The percentile compares how often this clinician performed the procedure
with other clinicians who performed it, as CMS calculates it. It measures
volume, not outcomes or skill.
Medicare patients and services, 2024
From the CMS Medicare Physician & Other Practitioners file for calendar
year 2024. It counts Original Medicare patients only, so a practice that
mostly sees Medicare Advantage or privately insured patients looks smaller
here than it is.
Medicare patients

Services billed
422

Dollar amounts are not shown. What Medicare pays a practice is gross
billings, before staff, premises and tax and including the cost of any
drugs it administers, so it is not what a clinician earns.
