$299,171

Medicare paid this office $299,171 for 408 people.

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

Procedures Medicare counted

Who their Medicare patients are

408 Original Medicare patients in 2024. Average age 74 · Under 65 8% · 85 and older 8% · Women 47% · Also on Medicaid 20% · Health risk score 1.39. Above the middle of the specialty; the typical orthopedic surgery clinician is at 1.13.

Conditions among them: High blood pressure 75% · Diabetes 27% · Coronary heart disease 27% · Chronic kidney disease 26% · Depression 23% · Atrial fibrillation 21% · Cancer 18% · Heart failure 15% · COPD 13% · Stroke 8% · Dementia 7%.

The office billed $1,888,481, Medicare allowed $380,101 and paid $299,171; for 1,310 services of 75 kinds.

Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

Year by year

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.

$1,422 in 2024

Medicaid paid $1,422 for 24 billed services this clinician did in 2024, up to 12 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

$2,871

Pharmacies billed $2,871 in 2024.

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

Opioids were 23% of their Part D prescriptions (32 of 139) in 2024. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 31%.

135 generic and fewer than 11 brand-name prescriptions · $2,871 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.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.

$53,653 in 2025

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.

Medicare did not publish checkup rates for this clinician.
