I will just start by saying always bill Medicare electronically (even secondary claims) if at all possible and then you won't run into this issue:
Back in 2006 Medicare released the first version of CMS 1500 forms (12-90) and recently came out with a newer version of CMS 1500 forms (08-05). On January 1st CMS began accepting the new CMS 1500 forms (08-05) with a planned cut off date of the old forms scheduled for April 1st 2007. CMS then identified formatting issues with the new CMS 1500 forms (08-05) but decided that as of July 2nd 2007 they were still no longer going to accept CMS 1500 (12-90) forms.
