CGM was only approved for 1 month....need support to fight Horizon BCBS of NJ

So I just found out that my CGM sensors may no longer be covered...I only had 1 month worth of sensors covered by my health insurance. I am interested in filing a class action law suit against Horizon Blue Cross and Blue Shield of NJ because I believe that it is illegal to approve coverage for an item and then deny coverage immediately after approval. If there is anyone who has this insurance and is interested in joining my law suit, please contact me!

Thanks, Paula
