Who their Medicare patients are

116 Original Medicare patients in 2024. Average age 78 · Women 24% · Health risk score 1.12. At or below the middle of the specialty; the typical urology clinician is at 1.36.

Conditions among them: High blood pressure 75% · Diabetes 27% · Chronic kidney disease 27% · Coronary heart disease 26% · Atrial fibrillation 24% · Cancer 23% · Heart failure 16% · Depression 16% · Dementia 13% · COPD 10%.

The office billed $216,817, Medicare allowed $67,561 and paid $53,655; for 645 services of 43 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

$14,262

Pharmacies billed $14,262 in 2024.

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

Opioids were 12% of their Part D prescriptions (33 of 269) in 2024. A higher opioid share than 9 in 10 peers; the typical urology clinician is at 2%.

255 generic and fewer than 11 brand-name prescriptions · $14,262 in drug cost · 55 antibiotic prescriptions to 38 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.
