Medicaid paid $10,243 for 320 billed services this clinician did in 2023, up to 17 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

$30,113

Pharmacies billed $30,113 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 7% of their Part D prescriptions (23 of 342) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%.

291 generic and fewer than 11 brand-name prescriptions · $30,113 in drug cost · 62 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.
