Erroneous Reimbursement Denials “Exceeds Auth” When All Are Not Used

BCBSM System Still Not Fixed - Keep Sending Us Your Denials!

BCBSM is denying claims for exceeds authorization when authorizations are not used up.  For example, AIM authorizes 6 treatments, the claim is submitted by NDC where the same HCPCS code can appear more than once on a claim.  Claims are processed without a problem the first couple of times, then denials are received stating you have exceeded your authorization limit. Why? This is occurring because the BCBSM system is processing each claim line as an authorized treatment day. You are left trying to contact AIM for additional authorizations or appeal your claims. 

This problem initially became apparent with drugs such as Vectibix, Zirabev, and Kadcyla, however, we’ve recently learned that this could happen on any drug where you use multiple vials or bill waste on a separate line.

Working with MSHO, BCBSM has been able to uncover the system issue and is currently working on a fix. In the meantime, BCBSM has agreed to manually process any claim denial for this system error MSHO members have received.  You do not have to appeal these claims or contact AIM for additional prior authorizations. 

Is this happening to you? What you need to do to have your claims manually addressed:

  1. Create a list of your denied claims and include the ICN number, date of service, and your NPI Number for each affected claim.
  2. Send this list to MSHO at We will immediately get them to BCBSM to have them processed promptly.  Turn around time should be quick (a week or two). 
  3. Please be sure not to include any other types of denials with your list.
  4. Please NEVER send patient names to MSHO.
