Drugs they prescribed that Part D paid

$111,803

Pharmacies billed $111,803 in 2024.

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

Opioids were 2% of their Part D prescriptions (11 of 617) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

541 generic and 76 brand-name prescriptions · $111,803 in drug cost · 35 antibiotic prescriptions to 19 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.
