CMS announced on Jan. 2, 2013, that they will not initiate enforcement action on the new Eligibility and Claims Status Operating Rules until March 31, 2013. However, the compliance date for using the operating rules remains January 1, 2013. This 90-day grace period is a result of feedback suggesting that a majority of HIPAA covered entities were unable to be in compliance with the operating rules by January 1, 2013.
