Back  RFI # 1694: Medi-Cal ERA

Formal vs. Informal Help Informal Formal


Kim Walker


A payer is returning ERA files to providers without a name in Loop 2100-NM1 Patient Name segment. Although the loop is required, NM103, NM104 and NM105 are marked as Situational, but noted that they are required when the patient has a last, first name.The payer is instead returning the patient's name in Loop 2100-NM1 Corrected Patient/Insured Name only.

Ex: NM1*QC*1~NM1*74*1*Last*First*D***C*policy no~

Can I have an interpretation of the usage of this Loop and Segment and specifically data elements NM103, NM104, NM105, please?

ERA Medi-Cal NM1*QC


The 5010 TR3 explicitly states that the Patient Name segment is required and MUST be sent. Elements NM101 , NM102 are required and NM103 is required for ALL claims that are not Retail Pharmacy. Elements NM104 and NM105 are situational, but the payer is required to send this information if it was received on the claim or if it is known.

The use of the Corrected Patient/Insured is for situations where the claim information is different than the information that the payer knows or has from their system or files. In those cases, the payer would supply the Corrected Patient/Insured segment (with the information from their files) along with the Patient Name segment (with the information from the claim). There is no situation in which the Patient Segment is not sent.
