Drugs they prescribed that Part D paid

$121,442

Pharmacies billed $121,442 in 2024.

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

Opioids were 1% of their Part D prescriptions (15 of 1,944) in 2024. At or below the middle of the specialty; the typical geriatric medicine clinician is at 2%.

1,777 generic and fewer than 11 brand-name prescriptions · $121,442 in drug cost · 20 antibiotic prescriptions to 19 people · 64 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.
