UB04 Condition Codes Code A1: EPSDT/CHAP

Overview

The provided sources do not contain any information about UB‑04 Condition Code A1 (EPSDT/CHAP). The Noridian Condition Codes list explicitly covers only numeric codes 01 through 77 and includes no alphanumeric codes such as A1. The excerpt from the MassHealth UB-04 Billing Guide does not reproduce the actual condition code set; it only provides front‑matter and a table of contents.

Because the instructions require that every statement be traced to the supplied source text and that no detail be written unless it appears in those sources, it is impossible to generate the required sections (Overview, When to Use, Step‑by‑Step Claim Example, Common Mistakes & Audit Red Flags, Related Codes/Fields) for code A1.

What the Sources Actually Say

• Noridian Condition Codes – The full extracted list shows only codes 01 through 77 (e.g., “01: Military service related”, “77: Provider accepts primary payer payment as pa…”). No code A1 or any letter‑based condition code appears.
  ^[1]

• MassHealth UB-04 Guide – The provided excerpt (pages 1‑4 and table of contents) does not include the condition code table or any mention of EPSDT/CHAP or code A1.

Conclusion

To write a valid article on Condition Code A1, one would need a source that defines it (e.g., the NUBC Official UB-04 Data Specifications Manual or a payer‑specific appendix). Since neither of the supplied sources addresses code A1, no content can be produced that complies with the absolute rule to only use provided sources.

If you can provide a source that includes the definition of Code A1 (e.g., “EPSDT/CHAP”), the article can be written immediately. Otherwise, the request cannot be fulfilled.
