In January, the Centers for Medicare & Medicaid Services announced that it had delayed enforcement of the required implementation of Version 5010 for 90 days. Though originally providers were expected to be in compliance with Version 5010 by Jan 1, 2012, it was projected that enforcement actions would begin on Apr 1, 2012.
In an email communication on Mar 8, CMS reported that currently, the vast majority of provider claims are being sent in 5010 format. As a result, CMS announced that effective Sun Apr 1, 2012 it will begin requiring that all Medicare Fee for Service Transactions be in submitted in Version 5010 format. CMS has provided a summary of transaction statistics confirming the use of Version 5010. CMS continues to offer a number of Version 5010 transition resources for providers.
