Year by year

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.

$698

Pharmacies billed $698 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

43 generic and fewer than 11 brand-name prescriptions · $698 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.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
