$27,546

Medicare paid this office $27,546 for 247 people.

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

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

247 Original Medicare patients in 2024. Average age 73 · Under 65 14% · 85 and older 10% · Women 39% · Also on Medicaid 36% · Health risk score 2.02. Above the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

Conditions among them: High blood pressure 75% · Chronic kidney disease 49% · Diabetes 36% · Coronary heart disease 27% · Atrial fibrillation 26% · Depression 26% · Cancer 23% · Heart failure 20% · COPD 13% · Dementia 11% · Stroke 10%.

The office billed $226,111, Medicare allowed $37,120 and paid $27,546; for 678 services of 25 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.

$1,357 in 2020

Medicaid paid $1,357 for 57 billed services this clinician did in 2020, up to 17 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.

$147,330

Pharmacies billed $147,330 in 2024.

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

Opioids were 3% of their Part D prescriptions (28 of 1,075) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%.

1,005 generic and fewer than 11 brand-name prescriptions · $147,330 in drug cost · 199 antibiotic prescriptions to 162 people.

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.

$69 in 2025

A payment is not proof that care is biased.
