Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

Medicaid work

Drugs they prescribed that Part D paid
$358
Pharmacies billed $358 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
24 generic and fewer than 11 brand-name prescriptions · $358 in drug cost.
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.
