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
$156,077
Pharmacies billed $156,077 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 3% of their Part D prescriptions (38 of 1,387) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.
1,170 generic and 193 brand-name prescriptions · $156,077 in drug cost · 37 antibiotic prescriptions to 27 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.
