Original Medicare doctor bills

$9,897

Medicare paid this office $9,897 for 54 people. Most of that is long return visits and Botox.

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

Largest Original Medicare bills
Long return visit (40+ min)41$7,700$145
Return visit (30+ min)16$1,856$103

Who their Medicare patients are

54 Original Medicare patients in 2024. Average age 73 · Women 78% · Also on Medicaid 22% · Health risk score 1.67. Above the middle of the specialty; the typical nurse practitioner clinician is at 1.42.

Conditions among them: Cancer 69% · High blood pressure 56% · Depression 26%.

The office billed $52,434, Medicare allowed $12,444 and paid $9,897; for 82 services of 8 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.

Drugs they prescribed that Part D paid

$11,434

Pharmacies billed $11,434 in 2024.

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

135 generic and 14 brand-name prescriptions · $11,434 in drug cost · 25 antibiotic prescriptions to 23 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.
