Set your calendars for the new CERT timeline, or lose you reimbursement. "Effective for all initial documentation request letters sent on or after January 1, 2014, providers and suppliers will have 60 days to submit medical documentation in response to initial documentation requests for claims selected by the Comprehensive Error Rate Testing (CERT) program," Medicare Administrative Contractors Palmetto GBA and CGS say on their websites. "If no documentation is received by the 60th day, the claim will be considered a ‘no documentation’ error and recoupment will be pursued."
