Medicaid work
$1,519 in 2024
Medicaid paid $1,519 for 27 billed services this clinician did in 2024, up to 14 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
$6,219
Pharmacies billed $6,219 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 22% of their Part D prescriptions (90 of 414) in 2024. Above the middle of the specialty; the typical physical medicine and rehabilitation clinician is at 12%.
412 generic and fewer than 11 brand-name prescriptions · $6,219 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.
