Medicaid paid $9,147 for 228 billed services this clinician did in 2024, up to 25 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

$24,045

Pharmacies billed $24,045 in 2024.

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

Opioids were 6% of their Part D prescriptions (16 of 274) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

233 generic and fewer than 11 brand-name prescriptions · $24,045 in drug cost · 29 antibiotic prescriptions to 25 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.

Largest Part D drug costs
Pantoprazole12$75$6
Atorvastatin13$65$5
Amoxicillin-Clavulanate Potass11$52$5
