Medicaid work

$5,424 in 2021

Medicaid paid $5,424 for 236 billed services this clinician did in 2021, up to 25 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

$295,374

Pharmacies billed $295,374 in 2024.

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

Opioids were 1% of their Part D prescriptions (18 of 2,852) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

2,563 generic and 274 brand-name prescriptions · $295,374 in drug cost · 39 antibiotic prescriptions to 24 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.
