Drugs they prescribed that Part D paid

$135,219

Pharmacies billed $135,219 in 2024.

Opioids were 0% of their Part D prescriptions (0 of 235) in 2024. At or below the middle of the specialty; the typical pain management clinician is at 44%.

127 generic and 108 brand-name prescriptions · $135,219 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.
