This is the CMS initiative where claims for certain defined services would result in claim denials if the ordering or referring physician or non-physician practitioner did not have an enrollment record in PECOS or had not validly opted out of Medicare. CMS noted it would advise providers of the new Phase 2 implementation date in the near future.
Prior to CMS' announcement of the implementation delay, two associations attempted to block this CMS initiative. On March 13, 2013, the Association of American Physicians & Surgeons, Inc. and the Alliance for Natural Health USA filed an emergency motion [PDF] for injunctive relief urging the court to stop the May 1, 2013 implementation of the Phase 2 edits. On April 17, 2013, the United States Circuit Court for the District of Columbia denied the motion.
