$189,440

Medicare paid this office $189,440 for 282 people.

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

Procedures Medicare counted

Who their Medicare patients are

282 Original Medicare patients in 2024. Average age 74 · Under 65 6% · 85 and older 12% · Women 43% · Also on Medicaid 21% · Health risk score 1.61. Above the middle of the specialty; the typical otolaryngology clinician is at 1.19.

Conditions among them: High blood pressure 65% · Diabetes 26% · Chronic kidney disease 22% · Coronary heart disease 21% · Atrial fibrillation 17% · Cancer 15% · Depression 15% · COPD 14% · Heart failure 13% · Stroke 10% · Dementia 6%.

The office billed $1,649,959, Medicare allowed $240,378 and paid $189,440; for 1,042 services of 83 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.

$2,733 in 2024

Medicaid paid $2,733 for 41 billed services this clinician did in 2024, up to 16 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.

$885

Pharmacies billed $885 in 2024.

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

65 generic and fewer than 11 brand-name prescriptions · $885 in drug cost · 23 antibiotic prescriptions to 18 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.

$21,768 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.
