GY and GZ modifiers, Advance Notice of Member Responsibility required for all claims that BCBSM is expected to reject

Beginning Sept. 1, 2014, all professional, non-Medicare claims that include the modifiers GY or GZ, along with modifier GA, will be rejected. The member will be responsible for paying for the services provided. Blue Cross Blue Shield of Michigan is adopting Medicare’s Advance Beneficiary Notice policy and refers to it as Advance Notice of Member Responsibility. Health care providers should include the GA modifier on all claims billed with a GY or GZ modifier. If providers don’t include the GA modifier on claims appended with a GY or GZ modifier, they will be held responsible for the cost of the services.
