Medicaid work
$14,180 in 2024
Medicaid paid $14,180 for 199 billed services this clinician did in 2024, up to 24 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
$116
Pharmacies billed $116 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 17) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
14 generic and fewer than 11 brand-name prescriptions · $116 in drug cost · 14 antibiotic prescriptions to 11 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.
