Drugs they prescribed that Part D paid
$175,399
Pharmacies billed $175,399 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 490) in 2024. At or below the middle of the specialty; the typical optometry clinician is at 0%.
229 generic and 261 brand-name prescriptions · $175,399 in drug cost · 23 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.
