$24,508

Medicare paid this office $24,508 for 212 people. Most of that is long return visits and Botox.

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

Who their Medicare patients are

212 Original Medicare patients in 2024. Average age 72 · Women 52% · Also on Medicaid 16% · Health risk score 1.41. At or below the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

Conditions among them: High blood pressure 75% · Depression 32% · Diabetes 24% · Coronary heart disease 24% · Chronic kidney disease 20% · Atrial fibrillation 14% · COPD 13% · Cancer 12% · Heart failure 10% · Stroke 8%.

The office billed $175,573, Medicare allowed $31,771 and paid $24,508; for 283 services of 13 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.

$78,394 in 2022

Medicaid paid $78,394 for 1,058 billed services this clinician did in 2022, up to 124 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.

$2,773

Pharmacies billed $2,773 in 2024.

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

Opioids were 21% of their Part D prescriptions (50 of 234) in 2024. A higher opioid share than 9 in 10 peers; the typical nurse practitioner clinician is at 0%.

230 generic and fewer than 11 brand-name prescriptions · $2,773 in drug cost · 38 antibiotic prescriptions to 26 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.

$59 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.
