Question: Are ASCs still required to append modifier SG to all claims?
Arkansas Subscriber
Answer: As of January 2008, Medicare no longer requires that you append modifier SG (Ambulatory surgical center facility service) for place of service (POS) 24 (Ambulatory surgical center). You can find these instructions on pages 10 and 15 of MLN Matters article MM5680, available on the CMS Web site at http://www.cms.hhs.gov/MLNMattersArticles/downloads/MM5680.pdf.
