Drugs they prescribed that Part D paid

$44,051

Pharmacies billed $44,051 in 2024.

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

Opioids were 40% of their Part D prescriptions (205 of 508) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%. Long-acting opioids: 34% of their opioid prescriptions.

459 generic and 49 brand-name prescriptions · $44,051 in drug cost.

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.
