$3,381

Medicare paid this office $3,381 for 36 people.

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

Who their Medicare patients are

36 Original Medicare patients in 2024. Average age 67 · Women 67% · Also on Medicaid 50% · Health risk score 2.31. Above the middle of the specialty; the typical pathology clinician is at 1.55.

Conditions among them: High blood pressure 58% · Depression 39% · Chronic kidney disease 36% · Diabetes 31%.

The office billed $22,655, Medicare allowed $4,352 and paid $3,381; for 97 services of 14 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.

$19,942 in 2024

Medicaid paid $19,942 for 554 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.
