These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

$26,873

Medicare paid this office $26,873 for 279 people.

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

Who their Medicare patients are

279 Original Medicare patients in 2024. Average age 75 · Under 65 6% · 85 and older 14% · Women 46% · Also on Medicaid 21% · Health risk score 1.49. At or below the middle of the specialty; the typical cardiology clinician is at 1.71.

Conditions among them: High blood pressure 75% · Coronary heart disease 59% · Atrial fibrillation 37% · Heart failure 34% · Chronic kidney disease 33% · Diabetes 32% · Depression 20% · Cancer 16% · COPD 14% · Stroke 13% · Dementia 8%.

The office billed $145,263, Medicare allowed $35,958 and paid $26,873; for 373 services of 17 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.

$276 in 2024

Medicaid paid $276 for 35 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.

$188,014

Pharmacies billed $188,014 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 965) in 2024. At or below the middle of the specialty; the typical cardiology clinician is at 0%.

792 generic and fewer than 11 brand-name prescriptions · $188,014 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.

$13,032 in 2025

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