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
$78,823
Pharmacies billed $78,823 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 2% of their Part D prescriptions (23 of 952) in 2024. Above the middle of the specialty; the typical family practice clinician is at 2%.
792 generic and 143 brand-name prescriptions · $78,823 in drug cost · 58 antibiotic prescriptions to 51 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.
