Medicaid work
$5,131 in 2023
Medicaid paid $5,131 for 43 billed services this clinician did in 2023, up to 16 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
$3,991
Pharmacies billed $3,991 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 24% of their Part D prescriptions (11 of 45) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
43 generic and fewer than 11 brand-name prescriptions · $3,991 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.
