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

$65,834

Medicare paid this office $65,834 for 256 people.

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

Who their Medicare patients are

256 Original Medicare patients in 2024. Average age 74 · Under 65 15% · 85 and older 22% · Women 54% · Also on Medicaid 56% · Health risk score 2.70. Sicker patients than 9 in 10 peers; the typical family practice clinician is at 1.13.

Conditions among them: High blood pressure 75% · Chronic kidney disease 50% · Depression 45% · Diabetes 40% · Heart failure 36% · Coronary heart disease 30% · Atrial fibrillation 30% · Dementia 27% · COPD 25% · Stroke 23% · Cancer 22%.

The office billed $250,343, Medicare allowed $84,762 and paid $65,834; for 611 services of 10 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.

$2,372 in 2024

Medicaid paid $2,372 for 111 billed services this clinician did in 2024, up to 25 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.

$14,146

Pharmacies billed $14,146 in 2024.

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

Opioids were 9% of their Part D prescriptions (14 of 149) in 2024. A higher opioid share than 9 in 10 peers; the typical family practice clinician is at 2%.

127 generic and fewer than 11 brand-name prescriptions · $14,146 in drug cost · 41 antibiotic prescriptions to 25 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.

$211 in 2025

A payment is not proof that care is biased.
