The office billed $11,009, Medicare allowed $4,381 and paid $3,491; for 46 services of 6 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.

Medicaid work

$1,895 in 2020

Medicaid paid $1,895 for 91 billed services this clinician did in 2020, up to 14 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

Drugs they prescribed that Part D paid

$10,569

Pharmacies billed $10,569 in 2024.

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

Opioids were 8% of their Part D prescriptions (13 of 156) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%.

132 generic and 24 brand-name prescriptions · $10,569 in drug cost · 21 antibiotic prescriptions to 17 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.
