Who their Medicare patients are

96 Original Medicare patients in 2024. Average age 73 · Women 58% · Also on Medicaid 27% · Health risk score 1.32. Above the middle of the specialty; the typical otolaryngology clinician is at 1.19.

Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

Drugs they prescribed that Part D paid

$4,205

Pharmacies billed $4,205 in 2024.

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

Opioids were 4% of their Part D prescriptions (13 of 296) in 2024. Above the middle of the specialty; the typical otolaryngology clinician is at 4%.

294 generic and fewer than 11 brand-name prescriptions · $4,205 in drug cost · 63 antibiotic prescriptions to 53 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.
