Medicare’s tentative timeline for implementing the revised CMS 1500 claim form (version 02/12) for Medicare Claims is as follows:
• January 6, 2014: Medicare begins receiving and processing paper claims submitted on the revised CMS 1500 claim form (version 02/12).
• January 6 through March 31, 2014: Dual use period during which Medicare continues to receive and process paper claims submitted on the old CMS 1500 claim form (version 08/05).
• April 1, 2014: Medicare receives and processes paper claims submitted only on the revised CMS 1500 claim form (version 02/12).
These dates are tentative and subject to change. CMS will provide more information as it is available.
