$94,424

Medicare paid this office $94,424 for 365 people.

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

Who their Medicare patients are

365 Original Medicare patients in 2024. Average age 75 · Under 65 9% · 85 and older 17% · Women 55% · Also on Medicaid 39% · Health risk score 2.03. At or below the middle of the specialty; the typical pulmonary disease clinician is at 2.13.

Conditions among them: High blood pressure 75% · COPD 50% · Chronic kidney disease 37% · Coronary heart disease 34% · Heart failure 33% · Atrial fibrillation 33% · Diabetes 30% · Depression 27% · Cancer 22% · Stroke 12% · Dementia 10%.

The office billed $479,296, Medicare allowed $124,694 and paid $94,424; for 897 services of 35 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.

$3,761 in 2023

Medicaid paid $3,761 for 44 billed services this clinician did in 2023, up to 15 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.

$329,774

Pharmacies billed $329,774 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 984) in 2024. At or below the middle of the specialty; the typical pulmonary disease clinician is at 0%.

352 generic and 632 brand-name prescriptions · $329,774 in drug cost · 64 antibiotic prescriptions to 46 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.

$23 in 2025

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

A payment is not proof that care is biased.
