$9,565

Medicare paid this office $9,565 for 71 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

71 Original Medicare patients in 2024. Average age 75 · Women 63% · Health risk score 1.00. At or below the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

Conditions among them: High blood pressure 52% · Chronic kidney disease 23% · Diabetes 18% · Coronary heart disease 18% · Cancer 15%.

The office billed $35,814, Medicare allowed $12,789 and paid $9,565; for 109 services of 15 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.

$0 in 2018

Medicaid paid $0 for 58 billed services this clinician did in 2018, up to 24 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.

$7,570

Pharmacies billed $7,570 in 2024.

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

109 generic and 25 brand-name prescriptions · $7,570 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.
