Medicaid work

Medicaid paid $8,964 for 519 billed services this clinician did in 2024, up to 24 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

$16,411

Pharmacies billed $16,411 in 2024.

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

Opioids were 7% of their Part D prescriptions (18 of 264) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%.

223 generic and fewer than 11 brand-name prescriptions · $16,411 in drug cost · 41 antibiotic prescriptions to 28 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.
