Drugs they prescribed that Part D paid

$7,380

Pharmacies billed $7,380 in 2024.

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

Opioids were 14% of their Part D prescriptions (25 of 182) in 2024. A higher opioid share than 9 in 10 peers; the typical sleep medicine clinician is at 0%. Long-acting opioids: 96% of their opioid prescriptions.

175 generic and fewer than 11 brand-name prescriptions · $7,380 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.
