# of Mastectomy Procedures Billed to Medicare

1-10

Total number of mastectomy procedures this clinician billed to Medicare in the most recent 12-month claims period, according to CMS.

Why is it showing a range? To protect patient privacy, CMS reports a "1-10" range for the number of procedures when a clinician bills Medicare only one to ten times for qualifying procedures.

Percentile Rank (%)

56% or below

A range of 1-10 procedures places a clinician at or below the 56th percentile.

The figures above reflect only procedures that this clinician billed to Medicare, according to CMS. Therefore, they may not reflect the total number of procedures this clinician performed during the 12-month reporting period. See Understanding CMS Data below.

Sara Wilson's Mastectomy Billing Volume Compared to Peers

CMS reports this clinician's count as a range rather than an exact number, so no single point can be marked. Every clinician CMS reports as 1-10 sits below every clinician with an exact count above that range, which puts them at or below the 56th percentile: the highlighted block. The shaded block covers the 3,027 clinicians CMS reports as 1-10, because CMS suppresses counts below 11.

Understanding CMS Data

This count includes partial removal of the breast (lumpectomy), removal of the whole breast, breast reconstruction after mastectomy, and the other breast procedures CMS lists in its "Mastectomy" category. CMS reports only procedures that clinicians billed to Original Medicare and Medicare Advantage. Therefore, CMS's procedure volume data does not include procedures that clinicians may have performed on patients who have other health care coverage (e.g., commercial insurance, self-pay, or the VA). Billing variation and coding errors can also affect CMS's data. Therefore, the number of procedures that CMS reports for a clinician may be higher or lower than the actual number of mastectomy procedures a clinician performed during the reporting period. Lastly, only clinicians with a primary specialty of General Surgery or Surgical Oncology (as reported to Medicare) are presented.

We use CMS's percentile formula with a narrower comparison group than CMS's own, so our percentile can differ from the one CMS publishes.
