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

$287,136

Pharmacies billed $287,136 in 2024.

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

Opioids were 2% of their Part D prescriptions (56 of 2,595) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%. Long-acting opioids: 23% of their opioid prescriptions.

2,183 generic and 387 brand-name prescriptions · $287,136 in drug cost · 44 antibiotic prescriptions to 34 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.
