We are getting close to the end of the clearinghouse migration from BCBSM. BCBSM is hoping to complete and end their transition and claim submissions by the end of October. If you haven’t started your move from BCBSM, you are already late. Their service could end at any time and you need to change clearinghouses immediately if you haven’t already done so.
