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

$100,948

Medicare paid this office $100,948 for 419 people.

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

Who their Medicare patients are

419 Original Medicare patients in 2024. Average age 77 · Under 65 8% · 85 and older 26% · Women 60% · Also on Medicaid 42% · Health risk score 2.29. Above the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Chronic kidney disease 68% · Coronary heart disease 46% · Heart failure 42% · Diabetes 40% · Atrial fibrillation 36% · Depression 36% · Dementia 28% · COPD 27% · Stroke 22% · Cancer 21%.

The office billed $444,723, Medicare allowed $128,798 and paid $100,948; for 946 services of 11 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.

$12,967 in 2024

Medicaid paid $12,967 for 414 billed services this clinician did in 2024, up to 32 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.

$20,903

Pharmacies billed $20,903 in 2024.

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

166 generic and fewer than 11 brand-name prescriptions · $20,903 in drug cost · 45 antibiotic prescriptions to 34 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.

$38 in 2024

A payment is not proof that care is biased.
