4 hospitals

These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

$130,516

Medicare paid this office $130,516 for 1,210 people.

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

Who their Medicare patients are

1,210 Original Medicare patients in 2024. Average age 75 · Under 65 11% · 85 and older 17% · Women 52% · Also on Medicaid 52% · Health risk score 2.58. Sicker patients than 9 in 10 peers; the typical diagnostic radiology clinician is at 1.7.

Conditions among them: High blood pressure 75% · Chronic kidney disease 49% · Diabetes 43% · Heart failure 38% · Coronary heart disease 35% · Atrial fibrillation 30% · Depression 30% · Cancer 25% · COPD 25% · Stroke 21% · Dementia 20%.

The office billed $1,661,385, Medicare allowed $164,387 and paid $130,516; for 2,514 services of 232 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.

$854 in 2024

Medicaid paid $854 for 198 billed services this clinician did in 2024, up to 33 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.

$4,330

Pharmacies billed $4,330 in 2024.

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

Opioids were 27% of their Part D prescriptions (11 of 41) in 2024. Too few prescriptions to compare fairly with other clinicians.

37 generic and fewer than 11 brand-name prescriptions · $4,330 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.

$2,592 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.

Medicare did not publish checkup rates for this clinician.
