Medicaid work

$3,948 in 2019

Medicaid paid $3,948 for 188 billed services this clinician did in 2019, 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

$154,416

Pharmacies billed $154,416 in 2024.

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

Opioids were 2% of their Part D prescriptions (30 of 1,841) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

1,643 generic and fewer than 11 brand-name prescriptions · $154,416 in drug cost · 40 antibiotic prescriptions to 26 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.
