Drugs they prescribed that Part D paid

$714,485

Pharmacies billed $714,485 in 2024.

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

Opioids were 4% of their Part D prescriptions (28 of 663) in 2024. Above the middle of the specialty; the typical hematopoietic cell transplantation and cellular therapy clinician is at 3%.

598 generic and 65 brand-name prescriptions · $714,485 in drug cost · 96 antibiotic prescriptions to 26 people.

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.
