$32,090

Medicare paid this office $32,090 for 246 people.

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

Who their Medicare patients are

246 Original Medicare patients in 2024. Average age 74 · Under 65 11% · 85 and older 11% · Women 69% · Also on Medicaid 17% · Health risk score 1.37. At or below the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

The office billed $238,417, Medicare allowed $41,898 and paid $32,090; for 472 services of 8 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.

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.

$146,479

Pharmacies billed $146,479 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 844) in 2024. At or below the middle of the specialty; the typical nurse practitioner clinician is at 0%.

657 generic and fewer than 11 brand-name prescriptions · $146,479 in drug cost · 12 antibiotic prescriptions.

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.

$98 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.

Medicare did not publish checkup rates for this clinician.
