On May 9, 2013, CMS announced a 60-day comment period on gapfill payment amounts for new molecular pathology codes under the Clinical Laboratory Fee Schedule (CLFS) for 2013 and 2014. The data includes Medicare Administrative Carrier (MAC) payment amounts and the MACs’ rationale for certain tests. CMS invites the public to submit specific cost, test methodology, and any other information relevant to the pricing review. CMS will post the final gapfill pricing decisions in September 2013, which will apply to payments for these test codes in 2013 and 2014. The public will have an additional 30 days to request reconsideration of decisions in the September file.
