Medicaid work
$2,229 in 2021
Medicaid paid $2,229 for 42 billed services this clinician did in 2021, up to 15 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
$126
Pharmacies billed $126 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 19) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
19 generic and 0 brand-name prescriptions · $126 in drug cost · 16 antibiotic prescriptions to 12 people.
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.
