$102,920

Medicare paid this office $102,920 for 8,228 people.

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

Who their Medicare patients are

8,228 Original Medicare patients in 2024. Average age 75 · Under 65 9% · 85 and older 16% · Women 49% · Also on Medicaid 27% · Health risk score 1.94. Above the middle of the specialty; the typical cardiology clinician is at 1.71.

Conditions among them: High blood pressure 75% · Coronary heart disease 42% · Atrial fibrillation 38% · Chronic kidney disease 37% · Diabetes 35% · Heart failure 34% · Cancer 23% · Depression 22% · COPD 17% · Stroke 14% · Dementia 13%.

The office billed $904,212, Medicare allowed $134,759 and paid $102,920; for 13,914 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.

$78,401 in 2024

Medicaid paid $78,401 for 7,407 billed services this clinician did in 2024, up to 676 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.

$17,469

Pharmacies billed $17,469 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 50) in 2024. At or below the middle of the specialty; the typical cardiology clinician is at 0%.

23 generic and 27 brand-name prescriptions · $17,469 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.

$172 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.

Medicare did not publish checkup rates for this clinician.
