NM102 qualifies NM103.

1.

NM110 and NM111 further define the type of entity in NM101.

Notes:

1. When there is only one referral on the claim, use “DN - Referring Provider”. When more than one referral exists and there is a requirement to report the additional referral, use code “DN” in the first iteration of this loop to indicate the referral received by the rendering provider on this claim. Use code “P3 - Primary Care Provider” in the second iteration of the loop to indicate the initial referral from the primary care provider or whatever provider wrote the initial referral for this patient’s episode of care being billed/reported in this transaction.
2. Because the usage of this segment is “situational” this is not a syntatically required loop. If the loop is used, then it is a “required” segment. See Appendix A for further details on ASC X12 nomenclature X12 syntax rules.
3. Required if claim involved a referral.

Example:
