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

$52,060

Medicare paid this office $52,060 for 313 people.

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

Who their Medicare patients are

313 Original Medicare patients in 2024. Average age 77 · Under 65 5% · 85 and older 18% · Women 55% · Also on Medicaid 32% · Health risk score 2.25. Above the middle of the specialty; the typical pulmonary disease clinician is at 2.13.

Conditions among them: High blood pressure 75% · Coronary heart disease 48% · COPD 48% · Diabetes 40% · Heart failure 40% · Chronic kidney disease 38% · Atrial fibrillation 35% · Cancer 31% · Depression 23% · Stroke 19% · Dementia 15%.

The office billed $248,152, Medicare allowed $68,803 and paid $52,060; for 454 services of 20 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.

$362 in 2023

Medicaid paid $362 for 14 billed services this clinician did in 2023, 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.

$128,433

Pharmacies billed $128,433 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 501) in 2024. At or below the middle of the specialty; the typical pulmonary disease clinician is at 0%.

286 generic and 215 brand-name prescriptions · $128,433 in drug cost · 66 antibiotic prescriptions to 17 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.

$212 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.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.

Medicare did not publish checkup rates for this clinician.
