$104,651

Medicare paid this office $104,651 for 405 people.

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

Who their Medicare patients are

405 Original Medicare patients in 2024. Average age 76 · Under 65 9% · 85 and older 23% · Women 54% · Also on Medicaid 33% · Health risk score 2.57. Above the middle of the specialty; the typical hospitalist clinician is at 2.49.

Conditions among them: High blood pressure 75% · Chronic kidney disease 48% · Depression 43% · Diabetes 42% · Heart failure 40% · Coronary heart disease 39% · Atrial fibrillation 35% · COPD 28% · Dementia 27% · Cancer 26% · Stroke 25%.

The office billed $370,720, Medicare allowed $132,533 and paid $104,651; for 1,289 services of 9 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.

$3,665 in 2024

Medicaid paid $3,665 for 71 billed services this clinician did in 2024, up to 14 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.

$28,229

Pharmacies billed $28,229 in 2024.

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

Opioids were 6% of their Part D prescriptions (15 of 254) in 2024. Above the middle of the specialty; the typical hospitalist clinician is at 4%.

209 generic and fewer than 11 brand-name prescriptions · $28,229 in drug cost · 79 antibiotic prescriptions to 48 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.

$25 in 2019

A payment is not proof that care is biased.
