Why are lines that are billed with the GA modifier automatically rejecting beneficiary liable?
The GA modifier has been redefined to mean “Waiver of Liability Statement Issued, as Required by Payer Policy.” This modifier is only to be used to report when a required Advance Beneficiary Notice (ABN) was issued for a service. The GA modifier should not be reported in association with any other liability-related modifier and should continue to be submitted with covered charges. Medicare systems will automatically deny these claims as a beneficiary liability (rather than subjecting them to possible medical review), and the beneficiary will have the right to appeal this determination.
