Medicaid work

$4,694 in 2024

Medicaid paid $4,694 for 455 billed services this clinician did in 2024, up to 19 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

$32,993

Pharmacies billed $32,993 in 2024.

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

Opioids were 4% of their Part D prescriptions (11 of 277) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

232 generic and fewer than 11 brand-name prescriptions · $32,993 in drug cost · 33 antibiotic prescriptions to 23 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.
