$274,523

Medicare paid this office $274,523 for 2,871 people.

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

Procedures Medicare counted

Who their Medicare patients are

2,871 Original Medicare patients in 2024. Average age 76 · Under 65 4% · 85 and older 16% · Women 47% · Also on Medicaid 11% · Health risk score 1.35. At or below the middle of the specialty; the typical undefined physician type clinician is at 1.67.

Conditions among them: High blood pressure 65% · Coronary heart disease 25% · Chronic kidney disease 23% · Cancer 22% · Diabetes 21% · Atrial fibrillation 19% · Heart failure 15% · Depression 14% · COPD 11% · Stroke 8% · Dementia 6%.

The office billed $3,437,264, Medicare allowed $362,164 and paid $274,523; for 8,616 services of 39 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.

$46,965 in 2024

Medicaid paid $46,965 for 1,250 billed services this clinician did in 2024, up to 95 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.

$147,992

Pharmacies billed $147,992 in 2024.

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

105 generic and fewer than 11 brand-name prescriptions · $147,992 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.

$11,750 in 2023

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

A payment is not proof that care is biased.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.

Medicare did not publish checkup rates for this clinician.
