$2,056,789

Medicare paid this office $2,056,789 for 401 people.

This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

The office billed $4,630,861, Medicare allowed $2,594,789 and paid $2,056,789; for 79,034 services of 90 kinds; $1,806,984 of it was for drugs given in the office and $249,805 for care.

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

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.

$6,181 in 2024

Medicaid paid $6,181 for 485 billed services this clinician did in 2024, up to 33 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.

$12,314,939

Pharmacies billed $12,314,939 in 2024.

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

296 generic and 1,539 brand-name prescriptions · $12,314,939 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.
