$17,920

Medicare paid this office $17,920 for 111 people.

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

Who their Medicare patients are

111 Original Medicare patients in 2024. Average age 67 · Under 65 21% · Women 52% · Also on Medicaid 38% · Health risk score 2.61. Sicker patients than 9 in 10 peers; the typical pathology clinician is at 1.55.

Conditions among them: High blood pressure 75% · Chronic kidney disease 45% · Coronary heart disease 37% · Diabetes 36% · Cancer 32% · Depression 29% · Heart failure 24% · Atrial fibrillation 22% · COPD 16% · Dementia 14% · Stroke 12%.

The office billed $210,096, Medicare allowed $22,490 and paid $17,920; for 580 services of 15 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.

$27,584 in 2024

Medicaid paid $27,584 for 505 billed services this clinician did in 2024, up to 27 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.

$28 in 2025

A payment is not proof that care is biased.
