How to fix ESD

This Emergency Department is under an Alternate Funding (APP) agreement for the service date - bill through the AFA arrangement instead of fee-for-service.

Referral and provider codes relate to the referring or rendering provider number, specialty restrictions, or referral requirements attached to the fee code. Verify the provider numbers on the claim and whether the code requires a valid referral.
