The office billed $35,307, Medicare allowed $3,693 and paid $2,701; for 33 services of 15 kinds.

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

Drugs they prescribed that Part D paid

$4,057

Pharmacies billed $4,057 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 30) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

23 generic and fewer than 11 brand-name prescriptions · $4,057 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.
