Medicare changed their timely filing definition for claims with dates of service beginning January 1, 2010.  Claims that are over one calendar year will now be rejected.  For the complete information on this and how transitional claims will be handled view CMS's article:

Also, myself and Teresa from our office are going to Atlanta this week for the Medisoft V17 Conference.  We will give up a complete update upon our return.

Happy Billing an Charting,
