Back  RFI # 256: 2330A/C REF=SY when Medicare

Formal vs. Informal Help Informal Formal


Ginger Wright


The 2330A Other Payer Subscriber Id Number REF01 Grey Box Note states "The SSN may not be used for Medicare." The 2330C Other Payer Patient Id Number REF01 Grey Box Note states "Do not use this code for Medicare." Does the use of the term 'may not' make it allowable to submit an SSN in the 2330A REF? Or should an SSN not be allowed in the 2330A REF as is the case in the 2330C REF when the other payer is Medicare?

2330A Medicare SSN


This issue is explicitly addressed in guide 004010X096. The notes on the 2330A and 2330C REF segment, element 1, code SY both state a requirement that the Social Security Number NOT be used when the information is related to Medicare as a payer. Use of the term "may not" is conveying the same level of restriction, just in a different voice. Since these loops are part of the Other Subscriber Information loop, the exclusion relates to situations where the corresponding 2330B loop identifies Medicare as the payer. The Social Security Number information may be sent when Medicare is not the payer in the corresponding 2330B loop and the other related conditions apply.
