CMS recently issued an update to Change Request 8443: Review Timeliness Requirements for Prepay Review. CR 8443 will change the number of days MACs have to conduct complex reviews from 60 days to 30 days.
The CMS update was to chage the transmittal number from Transmitttal 566 to the correct transmittal number, Transmittal 568. The update also added language that allows certain information from CR 8802 to be included. All other information in the request remains the same.
CR 8443 was implemented March 1, 2015. Get full details on CR 8443 here.
