Drugs they prescribed that Part D paid

$1,407

Pharmacies billed $1,407 in 2024.

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

Opioids were 17% of their Part D prescriptions (11 of 64) in 2024. At or below the middle of the specialty; the typical pain management clinician is at 44%.

63 generic and fewer than 11 brand-name prescriptions · $1,407 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.
