Original Medicare doctor bills

$9,566

Medicare paid this office $9,566 for 49 people.

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

Who their Medicare patients are

Conditions among them: High blood pressure 71% · Diabetes 31% · Depression 29% · Cancer 27% · Chronic kidney disease 24%.

The office billed $74,467, Medicare allowed $11,998 and paid $9,566; for 65 services of 32 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

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

Opioids were 0% of their 38 Part D prescriptions in 2020. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
