$279

Medicare paid this office $279 for 25 people.

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

Who their Medicare patients are

25 Original Medicare patients in 2024. Average age 76 · Under 65 0% · Women 48% · Also on Medicaid 100% · Health risk score 1.06. At or below the middle of the specialty; the typical family practice clinician is at 1.13.

Conditions among them: High blood pressure 75% · Diabetes 64%.

The office billed $2,781, Medicare allowed $473 and paid $279; for 27 services of 1 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.

$307,170 in 2024

Medicaid paid $307,170 for 3,642 billed services this clinician did in 2024, up to 141 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.

$136,095

Pharmacies billed $136,095 in 2024.

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

1,739 generic and fewer than 11 brand-name prescriptions · $136,095 in drug cost · 47 antibiotic prescriptions to 32 people · 11 antipsychotic prescriptions to people over 65.

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.

$63 in 2025

A payment is not proof that care is biased.
