Medicaid work

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
$444,130
Pharmacies billed $444,130 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 7% of their Part D prescriptions (249 of 3,377) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%. Long-acting opioids: 4% of their opioid prescriptions.
2,806 generic and 543 brand-name prescriptions · $444,130 in drug cost · 52 antibiotic prescriptions to 39 people · 14 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.
