Medicaid work

$92,787 in 2024

Medicaid paid $92,787 for 2,140 billed services this clinician did in 2024, up to 129 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

$1,301

Pharmacies billed $1,301 in 2024.

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

Opioids were 17% of their Part D prescriptions (19 of 112) in 2024. A higher opioid share than 9 in 10 peers; the typical nurse practitioner clinician is at 0%.

108 generic and fewer than 11 brand-name prescriptions · $1,301 in drug cost · 39 antibiotic prescriptions to 36 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.
