Drugs they prescribed that Part D paid

$8,072

Pharmacies billed $8,072 in 2024.

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

Opioids were 8% of their Part D prescriptions (15 of 183) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%.

167 generic and fewer than 11 brand-name prescriptions · $8,072 in drug cost · 41 antibiotic prescriptions to 39 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.
