Medicaid work

$105,478 in 2024

Medicaid paid $105,478 for 916 billed services this clinician did in 2024, up to 49 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

$202,963

Pharmacies billed $202,963 in 2024.

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

Opioids were 4% of their Part D prescriptions (12 of 296) in 2024. A higher opioid share than 9 in 10 peers; the typical neurology clinician is at 0%. Long-acting opioids: 100% of their opioid prescriptions.

258 generic and 38 brand-name prescriptions · $202,963 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.
