Blue Cross Blue Shield of Michigan retiring its local system

As a result of the migration of local groups to the NASCO platform, which was completed in 2012, there’s no longer a need for the local system. Therefore, the Blues will retire the local system, effective Oct. 31, 2014, and claims will no longer be processed on that system.

All claims filed on the local system must be submitted and received by Sept. 15, 2014, in order to be processed.

It’s imperative that all health care providers follow claim-filing deadlines. If you submit a claim after the filing limits, Blue Cross Blue Shield of Michigan will not offer any special handling or filing extensions, and no payment will be due from BCBSM or the subscriber.

To help you identify local group numbers, the formats on the ID card are typically as follows:

  • Local and Medicare Advantage group numbers: Five digits
  • MOS group numbers: Nine digits
  • NASCO group numbers: Five digits, usually starting with a seven or eight
  • BCN group numbers: Eight digits
