Original Medicare doctor bills
This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.
Procedures Medicare counted
| Hip replacement | 1-10 | None |
| Knee replacement | 1-10 | None |
Year by year
| 2023 | 90 | 109 | 74 | 1.51 | $228,776 | $16,469 |
| 2022 | 47 | 49 | 72 | 1.51 | $120,081 | $8,613 |
Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

Drugs they prescribed that Part D paid
$3,571
Pharmacies billed $3,571 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 36% of their Part D prescriptions (106 of 298) in 2024. Above the middle of the specialty; the typical orthopedic surgery clinician is at 31%.
296 generic and fewer than 11 brand-name prescriptions · $3,571 in drug cost · 125 antibiotic prescriptions to 90 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.
