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

Procedures Medicare counted

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

256 Original Medicare patients in 2024. Average age 77 · Under 65 6% · 85 and older 23% · Women 50% · Also on Medicaid 42% · Health risk score 1.44. 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 41% · Chronic kidney disease 34% · Depression 24% · Coronary heart disease 23% · Heart failure 21% · Atrial fibrillation 18% · Cancer 15% · COPD 13% · Dementia 8% · Stroke 6%.

The office billed $320,308, Medicare allowed $177,782 and paid $130,778; for 1,384 services of 23 kinds; $2,203 of it was for drugs given in the office and $128,575 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.

$2,051 in 2024

Medicaid paid $2,051 for 27 billed services this clinician did in 2024, up to 15 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.

$987,903

Pharmacies billed $987,903 in 2024.

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

Opioids were 1% of their Part D prescriptions (85 of 7,342) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

6,282 generic and 983 brand-name prescriptions · $987,903 in drug cost · 71 antibiotic prescriptions to 51 people · 73 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.
