Total number of varicose vein removal procedures this clinician billed to Medicare in the most recent 12-month claims period, according to CMS.
Percentile rank of 21 procedures compared to every other clinician CMS reports in this category, of any primary specialty, who has billed Medicare for at least one varicose vein removal procedure in the same period.
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.

David Rigberg's Varicose Vein Removal Billing Volume Compared to Peers
Reading the curve: find a volume along the bottom, and the line gives the percentile of every clinician CMS reports in this category, of any primary specialty at or below it. The marked point is this clinician. The shaded block covers the 3,160 clinicians CMS reports as 1-10, because CMS suppresses counts below 11.

CMS does not publish the start and end dates of the window behind any release, and consecutive releases may cover overlapping periods, or the same period with later-arriving claims added.
Understanding CMS Data
This count includes heat (radiofrequency or laser) ablation, medical adhesive closure, mechanochemical ablation, and sclerotherapy injections, and a patient who has treatment in more than one session contributes to the total each time. 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 varicose vein removal procedures a clinician performed during the reporting period. Lastly, we apply no specialty filter in this category, so this page includes clinicians of every primary specialty.
We apply CMS's percentile formula to the same pool CMS uses.
