There is some good news about the Medicare program's new requirement that claims must be filed within 12 months of the date of service. The one-calendar-year deadline applies only to claims with dates of service on or after Jan. 1, 2010, CMS says in a new MLN Matters article about the requirement. More details about the new requirement are in the article at www.cms.gov/MLNMattersArticles/downloads/MM6960.pdf.
