Medicaid work

$1,520 in 2023

Medicaid paid $1,520 for 40 billed services this clinician did in 2023, up to 15 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

$80,081

Pharmacies billed $80,081 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 82) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

66 generic and 16 brand-name prescriptions · $80,081 in drug cost.

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.
