$178,265

Medicare paid this office $178,265 for 663 people.

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

Procedures Medicare counted

Who their Medicare patients are

663 Original Medicare patients in 2024. Average age 76 · Under 65 5% · 85 and older 14% · Women 59% · Also on Medicaid 20% · Health risk score 1.13. At or below the middle of the specialty; the typical otolaryngology clinician is at 1.19.

Conditions among them: High blood pressure 72% · Diabetes 28% · Coronary heart disease 21% · Chronic kidney disease 21% · Atrial fibrillation 19% · Depression 19% · Cancer 16% · Heart failure 13% · COPD 13% · Stroke 9% · Dementia 7%.

The office billed $684,060, Medicare allowed $237,484 and paid $178,265; for 1,916 services of 60 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.

$23,405 in 2024

Medicaid paid $23,405 for 274 billed services this clinician did in 2024, up to 31 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.

$12,266

Pharmacies billed $12,266 in 2024.

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

Opioids were 4% of their Part D prescriptions (27 of 623) in 2024. Above the middle of the specialty; the typical otolaryngology clinician is at 4%.

584 generic and 39 brand-name prescriptions · $12,266 in drug cost · 37 antibiotic prescriptions to 31 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.

$1,137 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.

18 measures · 2023

Medicare asked this office to report how often certain checkups happened in 2023. This is not a grade for the doctor. A specialist’s patients may not need every screening.
