Drugs they prescribed that Part D paid
$46,070
Pharmacies billed $46,070 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 2% of their Part D prescriptions (13 of 683) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.
613 generic and fewer than 11 brand-name prescriptions · $46,070 in drug cost · 13 antibiotic prescriptions to 11 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.
