$181,812

Medicare paid this office $181,812 for 380 people.

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

Who their Medicare patients are

380 Original Medicare patients in 2024. Average age 78 · Under 65 5% · 85 and older 25% · Women 45% · Also on Medicaid 14% · Health risk score 2.50. Above the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Chronic kidney disease 75% · Diabetes 52% · Coronary heart disease 38% · Heart failure 34% · Atrial fibrillation 28% · Cancer 17% · Depression 16% · COPD 13% · Stroke 10% · Dementia 9%.

The office billed $363,009, Medicare allowed $244,737 and paid $181,812; for 1,205 services of 12 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.

$98,482 in 2024

Medicaid paid $98,482 for 416 billed services this clinician did in 2024, up to 41 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.

$290,386

Pharmacies billed $290,386 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 2,241) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

2,003 generic and 238 brand-name prescriptions · $290,386 in drug cost.

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.

$1,135 in 2025

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.
