How to fix A3G
The fee submitted is below the Schedule amount - bill the correct (full) fee for the code and resubmit.
These codes relate to the fee schedule code, diagnosis code, fee amount, or service limits in the Schedule of Benefits. The fix usually starts with re-reading the code's payment rules — effective dates, age/sex limits, maximums, and combinations — for the date of service.
