Medicaid work

$3,448 in 2024

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

$26,756

Pharmacies billed $26,756 in 2024.

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

Opioids were 9% of their Part D prescriptions (26 of 307) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%.

274 generic and fewer than 11 brand-name prescriptions · $26,756 in drug cost · 47 antibiotic prescriptions to 35 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.

Largest Part D drug costs
Prednisone23$102$4
Oxycodone21$79$4
