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
$393 in 2021
Medicaid paid $393 for 14 billed services this clinician did in 2021, up to 13 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.

| 2021 | 14 | 1 | 13 | $393 |
Drugs they prescribed that Part D paid
$70,423
Pharmacies billed $70,423 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
778 generic and fewer than 11 brand-name prescriptions · $70,423 in drug cost · 18 antibiotic prescriptions to 12 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.
