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

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

Procedures Medicare counted

Who their Medicare patients are

35 Original Medicare patients in 2024. Average age 75 · Women 43% · Also on Medicaid 37% · Health risk score 1.87. Sicker patients than 9 in 10 peers; the typical otolaryngology clinician is at 1.19.

Conditions among them: High blood pressure 71%.

The office billed $195,677, Medicare allowed $34,053 and paid $26,418; for 93 services of 36 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.

$505 in 2020

Medicaid paid $505 for 89 billed services this clinician did in 2020, up to 17 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.

$176 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.

Medicare did not publish checkup rates for this clinician.
