$81,630

Medicare paid this office $81,630 for 138 people.

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

Who their Medicare patients are

138 Original Medicare patients in 2024. Average age 79 · Women 73% · Also on Medicaid 85% · Health risk score 1.29. At or below the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Diabetes 36% · Chronic kidney disease 30% · Dementia 18% · Coronary heart disease 13% · Atrial fibrillation 13% · Depression 13% · Heart failure 12% · Cancer 12% · COPD 12%.

The office billed $199,574, Medicare allowed $111,373 and paid $81,630; for 1,238 services of 27 kinds; $7,933 of it was for drugs given in the office and $73,698 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.

$41,388 in 2024

Medicaid paid $41,388 for 437 billed services this clinician did in 2024, up to 37 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.

$645,179

Pharmacies billed $645,179 in 2024.

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

Opioids were 0% of their Part D prescriptions (16 of 5,588) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

4,894 generic and 656 brand-name prescriptions · $645,179 in drug cost · 48 antibiotic prescriptions to 33 people · 20 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.
