Procedures Medicare counted

Who their Medicare patients are

818 Original Medicare patients in 2024. Average age 77 · Under 65 3% · 85 and older 18% · Women 49% · Also on Medicaid 4% · Health risk score 1.15. At or below the middle of the specialty; the typical internal medicine clinician is at 1.76.

The office billed $832,926, Medicare allowed $325,650 and paid $262,140; for 3,526 services of 41 kinds; $48,232 of it was for drugs given in the office and $213,908 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.

$593,890

Pharmacies billed $593,890 in 2024.

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

Opioids were 6% of their Part D prescriptions (443 of 7,849) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%. Long-acting opioids: 15% of their opioid prescriptions.

6,994 generic and 837 brand-name prescriptions · $593,890 in drug cost · 149 antibiotic prescriptions to 95 people · 28 antipsychotic prescriptions to people over 65.

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.
