$21,411

Medicare paid this office $21,411 for 105 people.

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

Who their Medicare patients are

105 Original Medicare patients in 2024. Average age 72 · Women 67% · Also on Medicaid 23% · Health risk score 0.86. At or below the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

Conditions among them: High blood pressure 50% · Depression 19% · Diabetes 18% · Chronic kidney disease 16% · Cancer 13%.

The office billed $70,427, Medicare allowed $26,539 and paid $21,411; for 266 services of 33 kinds; $4,948 of it was for drugs given in the office and $16,463 for care.

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.

$44,476

Pharmacies billed $44,476 in 2024.

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

Opioids were 5% of their Part D prescriptions (39 of 781) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%.

694 generic and fewer than 11 brand-name prescriptions · $44,476 in drug cost · 21 antibiotic prescriptions to 15 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.
