Original Medicare doctor bills

$61,726

Medicare paid this office $61,726 for 133 people. Most of that is long return visits and Botox.

This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

Drugs they prescribed that Part D paid

$134,662

Pharmacies billed $134,662 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 1% of their Part D prescriptions (13 of 1,835) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

1,652 generic and fewer than 11 brand-name prescriptions · $134,662 in drug cost · 20 antibiotic prescriptions to 18 people.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.
