Original Medicare doctor bills

$77,421

Medicaid work

$299 in 2023

Medicaid paid $299 for 49 billed services this clinician did in 2023, 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

$5,094,428

Pharmacies billed $5,094,428 in 2024.

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

Opioids were 2% of their Part D prescriptions (27 of 1,623) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%.

1,238 generic and 385 brand-name prescriptions · $5,094,428 in drug cost.

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.
