1.

REF04 contains data relating to the value cited in REF02.

Notes:

1. Numbers at this position apply to the entire claim unless they are overridden in the REF segment in Loop ID-2400. A reference identification is considered to be overridden if the value in REF01 is the same in both the Loop ID-2300 REF segment and the Loop ID-2400 REF segment. In that case, the Loop ID-2400 REF applies only to that specific line.
2. Required where services on this claim were preauthorized or where a referral is involved. Generally, preauthorization/referral numbers are those numbers assigned by the payer/UMO to authorize a service prior to its being performed. The UMO (Utilization Management Organization) is generally the entity empowered to make a decision regarding the outcome of a health services review or the owner of information. The referral or prior authorization number carried in this REF is specific to the destination payer reported in the 2010BB loop. If other payers have similar numbers for this claim, report that information in the 2330 loop REF which holds that payer’s information.
