Medicaid work

$13,926 in 2024

Medicaid paid $13,926 for 1,109 billed services this clinician did in 2024, up to 57 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

$36,075

Pharmacies billed $36,075 in 2024.

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

Opioids were 6% of their Part D prescriptions (21 of 332) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

269 generic and fewer than 11 brand-name prescriptions · $36,075 in drug cost · 35 antibiotic prescriptions to 30 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.
