Drugs they prescribed that Part D paid
$18,433
Pharmacies billed $18,433 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 4% of their Part D prescriptions (14 of 402) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.
363 generic and 39 brand-name prescriptions · $18,433 in drug cost · 85 antibiotic prescriptions to 68 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.
