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
$49,944
Pharmacies billed $49,944 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 699) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.
633 generic and 66 brand-name prescriptions · $49,944 in drug cost · 12 antibiotic prescriptions.
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.
