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

Procedures Medicare counted

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

431 Original Medicare patients in 2024. Average age 76 · Under 65 3% · 85 and older 15% · Women 62% · Also on Medicaid 7% · Health risk score 1.07. At or below the middle of the specialty; the typical general practice clinician is at 1.33.

Conditions among them: High blood pressure 69% · Diabetes 26% · Chronic kidney disease 23% · Coronary heart disease 18% · Depression 15% · Cancer 14% · Atrial fibrillation 14% · Heart failure 12% · COPD 7% · Stroke 7% · Dementia 5%.

The office billed $262,813, Medicare allowed $126,385 and paid $96,325; for 1,015 services of 29 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.

$5,047 in 2023

Medicaid paid $5,047 for 79 billed services this clinician did in 2023, up to 18 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.

$52,320

Pharmacies billed $52,320 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 615) in 2024. At or below the middle of the specialty; the typical general practice clinician is at 0%.

398 generic and 217 brand-name prescriptions · $52,320 in drug cost · 23 antibiotic prescriptions to 23 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.

$61 in 2024

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

A payment is not proof that care is biased.
