Medicaid work
$1,812 in 2024
Medicaid paid $1,812 for 497 billed services this clinician did in 2024, up to 33 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
$1,012,203
Pharmacies billed $1,012,203 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 2% of their Part D prescriptions (391 of 23,344) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%. Long-acting opioids: 5% of their opioid prescriptions.
21,190 generic and 2,135 brand-name prescriptions · $1,012,203 in drug cost · 713 antibiotic prescriptions to 124 people · 592 antipsychotic prescriptions to people over 65.
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.
