Medicaid work

$5,469 in 2023

Medicaid paid $5,469 for 51 billed services this clinician did in 2023, up to 13 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

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

Opioids were 0% of their 15 Part D prescriptions in 2016. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
