$84,829

Medicare paid this office $84,829 for 598 people.

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

Who their Medicare patients are

598 Original Medicare patients in 2024. Average age 75 · Under 65 6% · 85 and older 11% · Women 66% · Also on Medicaid 13% · Health risk score 1.10. At or below the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

The office billed $379,624, Medicare allowed $108,388 and paid $84,829; for 5,142 services of 56 kinds; $4,831 of it was for drugs given in the office and $79,998 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.

$1,691 in 2024

Medicaid paid $1,691 for 16 billed services this clinician did in 2024, up to 16 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.

$2,781

Pharmacies billed $2,781 in 2024.

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

Opioids were 6% of their Part D prescriptions (27 of 457) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%.

456 generic and fewer than 11 brand-name prescriptions · $2,781 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.

$74 in 2025

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.
