Drugs they prescribed that Part D paid

$62,098

Pharmacies billed $62,098 in 2024.

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

Opioids were 2% of their Part D prescriptions (26 of 1,411) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

1,336 generic and 75 brand-name prescriptions · $62,098 in drug cost · 26 antibiotic prescriptions to 18 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.
