$97,690

Medicare paid this office $97,690 for 223 people.

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

Who their Medicare patients are

223 Original Medicare patients in 2024. Average age 75 · Under 65 7% · 85 and older 16% · Women 78% · Also on Medicaid 69% · Health risk score 1.26. At or below the middle of the specialty; the typical rheumatology clinician is at 1.38.

The office billed $260,303, Medicare allowed $129,184 and paid $97,690; for 3,238 services of 25 kinds; $24,226 of it was for drugs given in the office and $73,464 for care.

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.

$5,338 in 2024

Medicaid paid $5,338 for 906 billed services this clinician did in 2024, up to 57 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.

$4,037,963

Pharmacies billed $4,037,963 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 2,936) in 2024. At or below the middle of the specialty; the typical rheumatology clinician is at 3%.

2,029 generic and 882 brand-name prescriptions · $4,037,963 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.

$3,095 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.
