How to fix ESF
You aren't eligible to bill this service - confirm your registration and criteria for the service date before resubmitting.
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.
