Who their Medicare patients are

168 Original Medicare patients in 2024. Average age 74 · Under 65 8% · 85 and older 12% · Women 52% · Also on Medicaid 11% · Health risk score 1.43. Above the middle of the specialty; the typical otolaryngology clinician is at 1.19.

The office billed $288,541, Medicare allowed $92,283 and paid $71,437; for 430 services of 67 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.

Medicaid work

$5,001 in 2023

Medicaid paid $5,001 for 69 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.

Drugs they prescribed that Part D paid

$2,393

Pharmacies billed $2,393 in 2024.

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

Opioids were 13% of their Part D prescriptions (33 of 249) in 2024. Above the middle of the specialty; the typical otolaryngology clinician is at 4%.

246 generic and fewer than 11 brand-name prescriptions · $2,393 in drug cost · 23 antibiotic prescriptions to 13 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.
