Drugs they prescribed that Part D paid
$62,210
Pharmacies billed $62,210 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 339) in 2024. At or below the middle of the specialty; the typical infectious disease clinician is at 0%.
316 generic and 23 brand-name prescriptions · $62,210 in drug cost · 277 antibiotic prescriptions to 69 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.
