Medicaid work
$2,603 in 2021
Medicaid paid $2,603 for 214 billed services this clinician did in 2021, up to 19 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
$1,173,123
Pharmacies billed $1,173,123 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 1% of their Part D prescriptions (16 of 1,751) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.
1,384 generic and fewer than 11 brand-name prescriptions · $1,173,123 in drug cost · 19 antibiotic prescriptions to 11 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.
