The office billed $79,369, Medicare allowed $33,093 and paid $26,019; for 297 services of 20 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.

Drugs they prescribed that Part D paid

$2,501

Pharmacies billed $2,501 in 2024.

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

Opioids were 13% of their Part D prescriptions (23 of 178) in 2024. At or below the middle of the specialty; the typical plastic and reconstructive surgery clinician is at 28%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

178 generic and 0 brand-name prescriptions · $2,501 in drug cost · 37 antibiotic prescriptions to 34 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.
