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

$397,363

Pharmacies billed $397,363 in 2024.

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

Opioids were 1% of their Part D prescriptions (27 of 3,718) in 2024. At or below the middle of the specialty; the typical geriatric medicine clinician is at 2%.

3,211 generic and 487 brand-name prescriptions · $397,363 in drug cost · 73 antibiotic prescriptions to 43 people · 39 antipsychotic prescriptions to people over 65.

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.
