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.

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.
Payments from drug and device companies, 2025
Drug and device makers are required by federal law (the Physician Payments
Sunshine Act) to report what they pay or give to clinicians, and CMS
publishes the reports as Open Payments. This is the 2025 program
year. A report is a record of a payment, not an allegation of anything,
and many are small items such as meals. Only general payments are listed
here; research payments and ownership or investment interests are
reported separately by CMS and are not shown.
Food and Beverage
$141 6 payments · a meal or drink at a meeting or visit, not a fee
Each amount is the sum of what companies reported for that kind of
payment in 2025, rounded to the dollar. Not all of it is income to
the clinician: a meal is not a fee, a charitable contribution goes to a
charity, and a royalty or an acquisition payment is not a salary.

Open Payments.
Corrections go through CMS’s dispute process. This site removes a
home address on request and asks for no proof, because that is privacy;
it will not remove an accurate payment report on request, because that is
a statutory public disclosure.
