$1,745,029

Medicare paid this office $1,745,029 for 214 people.

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

The office billed $8,445,557, Medicare allowed $2,194,995 and paid $1,745,029; for 110,140 services of 102 kinds; $1,658,979 of it was for drugs given in the office and $86,050 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.

$2,361,415

Pharmacies billed $2,361,415 in 2024.

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

Opioids were 3% of their Part D prescriptions (26 of 829) in 2024. Above the middle of the specialty; the typical nurse practitioner clinician is at 0%.

615 generic and 214 brand-name prescriptions · $2,361,415 in drug cost · 12 antibiotic prescriptions.

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.

$54 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.
