Drugs they prescribed that Part D paid

$647,559

Pharmacies billed $647,559 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 817) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

519 generic and fewer than 11 brand-name prescriptions · $647,559 in drug cost · 16 antibiotic prescriptions.

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.
