Drugs they prescribed that Part D paid
$4,283
Pharmacies billed $4,283 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 180) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.
160 generic and fewer than 11 brand-name prescriptions · $4,283 in drug cost · 82 antibiotic prescriptions to 72 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.
