Public record actions

18 measures · 2023

Medicare asked this office to report how often certain checkups happened in 2023. This is not a grade for the doctor. A specialist’s patients may not need every screening.

These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

$103,907

Medicare paid this office $103,907 for 229 people.

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

229 Original Medicare patients in 2024. Average age 80 · 85 and older 27% · Women 87% · Also on Medicaid 5% · Health risk score 1.23. At or below the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Coronary heart disease 35% · Diabetes 33% · Chronic kidney disease 33% · Atrial fibrillation 23% · Heart failure 19% · Depression 17% · Stroke 14% · Cancer 13% · COPD 13% · Dementia 10%.

The office billed $219,323, Medicare allowed $138,404 and paid $103,907; for 1,976 services of 37 kinds; $3,289 of it was for drugs given in the office and $100,619 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.

$1,529,171

Pharmacies billed $1,529,171 in 2024.

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

Opioids were 2% of their Part D prescriptions (231 of 11,856) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

9,776 generic and 1,991 brand-name prescriptions · $1,529,171 in drug cost · 397 antibiotic prescriptions to 222 people · 57 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.
