$176,988

Medicare paid this office $176,988 for 298 people.

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

Who their Medicare patients are

298 Original Medicare patients in 2024. Average age 77 · Under 65 12% · 85 and older 30% · Women 48% · Also on Medicaid 47% · Health risk score 3.31. Above the middle of the specialty; the typical infectious disease clinician is at 3.

Conditions among them: High blood pressure 75% · Chronic kidney disease 55% · Diabetes 51% · Heart failure 48% · Coronary heart disease 44% · Atrial fibrillation 41% · Depression 40% · COPD 33% · Dementia 32% · Cancer 22% · Stroke 20%.

The office billed $630,308, Medicare allowed $224,312 and paid $176,988; for 1,593 services of 7 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.

$19,391 in 2024

Medicaid paid $19,391 for 410 billed services this clinician did in 2024, up to 29 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.

$2,265

Pharmacies billed $2,265 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 22) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

21 generic and fewer than 11 brand-name prescriptions · $2,265 in drug cost · 13 antibiotic prescriptions.

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.

$122 in 2023

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

A payment is not proof that care is biased.
