Drugs they prescribed that Part D paid
$135,219
Pharmacies billed $135,219 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
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.
