$20,837

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

Who their Medicare patients are

144 Original Medicare patients in 2024. Average age 77 · Under 65 10% · 85 and older 26% · Women 56% · Also on Medicaid 38% · Health risk score 2.29. Above the middle of the specialty; the typical emergency medicine clinician is at 2.01.

The office billed $217,158, Medicare allowed $26,720 and paid $20,837; for 220 services of 8 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.

$32,254 in 2024

Medicaid paid $32,254 for 586 billed services this clinician did in 2024, up to 63 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.

$1,366

Pharmacies billed $1,366 in 2024.

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

Opioids were 16% of their Part D prescriptions (11 of 70) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.

66 generic and fewer than 11 brand-name prescriptions · $1,366 in drug cost · 36 antibiotic prescriptions to 31 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.

$15 in 2025

A payment is not proof that care is biased.
