Drugs they prescribed that Part D paid

$2,366

Pharmacies billed $2,366 in 2024.

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

66 generic and fewer than 11 brand-name prescriptions · $2,366 in drug cost · 50 antibiotic prescriptions to 19 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.

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.
