If you have Medicare Fee-For-Service claims with service dates from Oct 1, 2009, through Dec 31, 2009, those claims MUST be filed by Dec 31, 2010, or Medicare will deny those claims. Claims with service dates from Jan 1, 2009, to Oct 1, 2009, keep their original Dec 31, 2010 deadline for filing.
Claims for services that require reporting a line item date of service, the line item date will be used to determine the date of service. For other claims, the claim statement’s “From” date is used to determine the date of service.
For additional information about the new maximum period for claims submission filing dates, contact your Medicare contractor, or review the MLN Matters articles listed below related to this subject:
