$5,928

Medicare paid this office $5,928 for 17 people.

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

Who their Medicare patients are

17 Original Medicare patients in 2024. Average age 71 · Health risk score 2.78. Above the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

Conditions among them: High blood pressure 71%.

The office billed $40,951, Medicare allowed $7,440 and paid $5,928; for 100 services of 5 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.

$1,318

Pharmacies billed $1,318 in 2024.

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

11 generic and 0 brand-name prescriptions · $1,318 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.

$220 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.
