Medicaid work

$11,734 in 2024

Medicaid paid $11,734 for 349 billed services this clinician did in 2024, up to 29 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

$1,354

Pharmacies billed $1,354 in 2024.

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

Opioids were 14% of their Part D prescriptions (20 of 139) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.

126 generic and 13 brand-name prescriptions · $1,354 in drug cost · 34 antibiotic prescriptions to 32 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.
