Medicaid work

$3,930 in 2024

Medicaid paid $3,930 for 54 billed services this clinician did in 2024, up to 14 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

$16,273

Pharmacies billed $16,273 in 2024.

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

Opioids were 3% of their Part D prescriptions (12 of 384) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

330 generic and fewer than 11 brand-name prescriptions · $16,273 in drug cost · 54 antibiotic prescriptions to 43 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.
