Form CMS – 1500 Revised Timeline

The Centers for Medicare and Medicaid Services (CMS) has revised the Form CMS-1500 (12/90) to accommodate the reporting of the National Provider Identifier (NPI) which is scheduled for mandatory implementation on May 23, 2007. The revised Form CMS-1500 is the 08/05 version. The new version will be implemented January 2, 2007. Providers will not be mandated to use the revised Form CMS-1500 (08/05) until April 02, 2007.

The following is the Form CMS-1500 (08/05) version implementation timeline (revised June 30, 2006):

• January 02, 2007: Health plans, clearinghouses, and other information support vendors should be ready to handle and accept the revised Form CMS-1500 (08/05).
• January 02, 2007 – March 30, 2007: Providers can use either the current Form CMS-1500 (12/90) version or the revised Form CMS-1500 (08/05) version.
• April 02, 2007: The current Form CMS-1500 (12/90) version is discontinued; only the revised Form CMS-1500 (08/05) will be accepted. All claims re-billed on/after 4/2/07 must be submitted on the revised Form CMS-1500 (08/05).

To prevent the return of your paper claims:

• Do not submit your NPI on the current Form CMS-1500 (12/90)
