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

The office billed $39,983, Medicare allowed $12,362 and paid $9,817; for 111 services of 6 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.

$1,781 in 2024

Medicaid paid $1,781 for 61 billed services this clinician did in 2024, up to 14 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.
