Medicaid work
$55,007 in 2024
Medicaid paid $55,007 for 1,695 billed services this clinician did in 2024, up to 95 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
$59
Pharmacies billed $59 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 13) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
13 generic and 0 brand-name prescriptions · $59 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.
