Original Medicare doctor bills

The office billed $486, Medicare allowed $295 and paid $273; for 18 services of 6 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 paid $342,902 for 4,187 billed services this clinician did in 2024, up to 171 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

$199,200

Pharmacies billed $199,200 in 2024.

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

Opioids were 3% of their Part D prescriptions (57 of 1,958) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%.

1,603 generic and 341 brand-name prescriptions · $199,200 in drug cost · 28 antibiotic prescriptions to 22 people · 12 antipsychotic prescriptions to people over 65.

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.
