UB04 Condition Codes Code D4: Change in ICD-10 Diagnosis Codes

I cannot complete the requested article because the provided sources do not contain condition code D4 or any reference to a "Change in ICD‑10 Diagnosis Codes" meaning.

• The ^[1] extraction you pasted includes only codes 01 through 77—none of which list D4.
• The ^[2] provides general UB‑04 instructions but does not define condition code D4.

Without a source explicitly stating the code and its meaning, I cannot write the sections you requested (Overview, When to Use, Claim Example, Common Mistakes, Related Codes) while following the absolute rules to trace every claim and cite every sentence.

If you can provide a source that includes condition code D4 (e.g., the full Noridian page or a NUBC manual), I will be happy to write the complete article. Alternatively, I can write a similar piece about another condition code that is present in your sources, such as code 44 (Inpatient admission changed to outpatient), code 15 (Clean claim delayed…), or code 17 (Patient is homeless). Let me know.
