These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

$3,649

Medicare paid this office $3,649 for 45 people.

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

Who their Medicare patients are

45 Original Medicare patients in 2024. Average age 76 · Women 44% · Health risk score 1.46. Above the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

Conditions among them: High blood pressure 73% · Depression 36% · Diabetes 33% · Chronic kidney disease 31% · Atrial fibrillation 31% · Heart failure 29%.

The office billed $12,584, Medicare allowed $4,577 and paid $3,649; for 46 services of 6 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.

$3,567

Pharmacies billed $3,567 in 2024.

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

Opioids were 55% of their Part D prescriptions (18 of 33) in 2024. Too few prescriptions to compare fairly with other clinicians.

27 generic and fewer than 11 brand-name prescriptions · $3,567 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.

$156 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.
