The Centers for Medicare & Medicaid Services has extended the deadline to review and comment on the quarterly Dialysis Facility Compare preview reports for dialysis facilities to Dec. 2 at 5:00 p.m. ET.

CMS announced Nov. 7 that it had finalized the methodology for its Dialysis Facility Compare Star Rating program and was releasing previews of ratings to individual dialysis facilities. Dialysis facilities originally had 15 days to review their ratings. CMS said it expects to post ratings to Dialysis Facility Compare in January 2015.

Kidney Care Partners, which represents patient advocates, clinicians, care professionals, dialysis providers, researchers and manufacturers, said CMS' methodology for the star rating system for dialysis providers "distorts the actual quality performance of dialysis facilities."  But CMS has stood by its rating system, which is set to go live on Dialysis Facility Compare in January.
