Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

Year by year

20231113721.29$72,236$4,203

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.

Drugs they prescribed that Part D paid

$6,424

Pharmacies billed $6,424 in 2024.

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

12 generic and fewer than 11 brand-name prescriptions · $6,424 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.
