$10,442

Medicare paid this office $10,442 for 115 people.

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

Who their Medicare patients are

115 Original Medicare patients in 2024. Average age 70 · Women 57% · Also on Medicaid 24% · Health risk score 0.96. At or below the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 57% · Depression 20% · Diabetes 18% · Coronary heart disease 18% · Cancer 13% · Chronic kidney disease 12% · Atrial fibrillation 10%.

The office billed $65,104, Medicare allowed $14,775 and paid $10,442; for 227 services of 34 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.

$20,663 in 2024

Medicaid paid $20,663 for 147 billed services this clinician did in 2024, up to 22 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.

$3,679

Pharmacies billed $3,679 in 2024.

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

56 generic and 12 brand-name prescriptions · $3,679 in drug cost · 16 antibiotic prescriptions to 14 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.

$19 in 2025

A payment is not proof that care is biased.
