Drugs they prescribed that Part D paid

$1,054,270

Pharmacies billed $1,054,270 in 2024.

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

1,525 generic and 409 brand-name prescriptions · $1,054,270 in drug cost · 119 antibiotic prescriptions to 82 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.
