Original Medicare doctor bills
This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.
Procedures Medicare counted
| Coronary artery bypass graft (CABG) | 1-10 | None |
| Leg revascularization (restoring blood flow) | 13 | More than 62% of doctors who do this |
| Varicose vein removal | 1-10 | None |
Drugs they prescribed that Part D paid
$976
Pharmacies billed $976 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 17) in 2024. Too few prescriptions to compare fairly with other clinicians.
16 generic and fewer than 11 brand-name prescriptions · $976 in drug cost.
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.
| Clopidogrel | 11 | $87 | $8 |
Year by year
| 2024 | 17 | None | 0% (0) | None | $976 |
| 2021 | 28 | 27 | 86% (24) | 0% | $95 |
Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
