$86,938

Medicare paid this office $86,938 for 305 people.

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

Who their Medicare patients are

305 Original Medicare patients in 2024. Average age 78 · Under 65 10% · 85 and older 31% · Women 47% · Also on Medicaid 45% · Health risk score 2.70. Above the middle of the specialty; the typical hospitalist clinician is at 2.49.

Conditions among them: High blood pressure 75% · Diabetes 51% · Coronary heart disease 48% · Atrial fibrillation 45% · Dementia 44% · Heart failure 43% · Chronic kidney disease 41% · Depression 40% · COPD 30% · Stroke 25% · Cancer 22%.

The office billed $490,529, Medicare allowed $109,477 and paid $86,938; for 1,000 services of 8 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.

$6,796 in 2024

Medicaid paid $6,796 for 525 billed services this clinician did in 2024, up to 23 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.

$16,665

Pharmacies billed $16,665 in 2024.

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

Opioids were 5% of their Part D prescriptions (14 of 270) in 2024. Above the middle of the specialty; the typical hospitalist clinician is at 4%.

235 generic and fewer than 11 brand-name prescriptions · $16,665 in drug cost · 64 antibiotic prescriptions to 49 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.

$96 in 2024

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

A payment is not proof that care is biased.
