Medicaid work
$1,970 in 2023
Medicaid paid $1,970 for 586 billed services this clinician did in 2023, up to 51 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
$5,413
Pharmacies billed $5,413 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 30) in 2024. Too few prescriptions to compare fairly with other clinicians.
0 generic and 20 brand-name prescriptions · $5,413 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.
