According to a recent alert on the Centers for Medicare and Medicaid Services (CMS) website, physicians and other providers are required to begin using a new ABN form when services are expected to not be covered by medicare. According to the alert, beginning Monday, March 3, 2008, physicians may use the revised ABN for all situations where Medicare payment is expected to be denied. The revised ABN replaces the existing ABN-G (Form CMS-R-131G), ABN-L (Form CMS-R-131L), and NEMB (Form CMS-20007). CMS will allow a 6-month transition period from the date of implementation for use of the revised form and instructions. Accordingly providers and suppliers must begin using the revised ABN no later than September 1, 2008.
