$4,264

Medicare paid this office $4,264 for 21 people.

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

Who their Medicare patients are

21 Original Medicare patients in 2024. Average age 71 · Health risk score 0.57. At or below the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

The office billed $35,532, Medicare allowed $6,133 and paid $4,264; for 73 services of 14 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.

$7,237

Pharmacies billed $7,237 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 87) in 2024. At or below the middle of the specialty; the typical nurse practitioner clinician is at 0%.

74 generic and 13 brand-name prescriptions · $7,237 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.

$29 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.
