$37,680

Medicare paid this office $37,680 for 298 people.

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

Who their Medicare patients are

298 Original Medicare patients in 2024. Average age 73 · Under 65 14% · 85 and older 19% · Women 56% · Also on Medicaid 32% · Health risk score 1.99. At or below the middle of the specialty; the typical emergency medicine clinician is at 2.01.

Conditions among them: High blood pressure 75% · Diabetes 48% · Coronary heart disease 38% · Chronic kidney disease 35% · Depression 31% · Heart failure 30% · COPD 28% · Atrial fibrillation 27% · Stroke 20% · Dementia 19% · Cancer 12%.

The office billed $430,554, Medicare allowed $49,513 and paid $37,680; for 319 services of 16 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.

$57,368 in 2024

Medicaid paid $57,368 for 903 billed services this clinician did in 2024, up to 34 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.

$1,389

Pharmacies billed $1,389 in 2024.

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

153 generic and fewer than 11 brand-name prescriptions · $1,389 in drug cost · 72 antibiotic prescriptions to 66 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.

$23 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.
