The office billed $472,983, Medicare allowed $65,806 and paid $51,455; for 443 services of 40 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.

20231923711.83$4,342$1,720

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.

Medicaid work

$1,392 in 2024

Medicaid paid $1,392 for 31 billed services this clinician did in 2024, 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.

Drugs they prescribed that Part D paid

$4,941

Pharmacies billed $4,941 in 2024.

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

Opioids were 9% of their Part D prescriptions (12 of 138) in 2024. Above the middle of the specialty; the typical otolaryngology clinician is at 4%.

136 generic and fewer than 11 brand-name prescriptions · $4,941 in drug cost · 33 antibiotic prescriptions to 27 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.

Largest Part D drug costs
Amoxicillin-Clavulanate Potass21$672$32
Azelastine29$574$20
Ipratropium20$566$28
Mupirocin15$162$11
