REF04 contains data relating to the value cited in REF02.

Notes:

1. Use this only if the subscriber is the patient.
2. This is the payer’s assigned control number, also known as, Internal Control Number (ICN), Document Control Number (DCN), or Claim Control Number (CCN). This should be sent on claim inquiries when the number is known.
3. The authors recommend sending this segment on claim inquires when the information is known. It will provide a direct look up key into the payer’s adjudication system and will reduce the possibility of returning more claim status information than was intended. For example, when a claim status inquiry is performed and many claims meet the conditions of the inquiry all will be returned. By providing the information within this particular segment the search criteria is narrowed to the specific claim in question.
4. The total number of REF segments in the 2200 Loop cannot exceed 3.
