$84,629

Medicare paid this office $84,629 for 505 people.

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

Who their Medicare patients are

505 Original Medicare patients in 2024. Average age 80 · Under 65 4% · 85 and older 37% · Women 55% · Also on Medicaid 26% · Health risk score 2.02. Above the middle of the specialty; the typical emergency medicine clinician is at 2.01.

The office billed $717,890, Medicare allowed $106,972 and paid $84,629; for 694 services of 41 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.

$21,561 in 2024

Medicaid paid $21,561 for 538 billed services this clinician did in 2024, up to 42 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.

$2,794

Pharmacies billed $2,794 in 2024.

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

Opioids were 10% of their Part D prescriptions (12 of 118) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.

110 generic and fewer than 11 brand-name prescriptions · $2,794 in drug cost · 47 antibiotic prescriptions to 41 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.

Year by year

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