K35.200

Billable

Acute appendicitis with generalized peritonitis, without perforation or abscess

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Acute inflammation of the appendix with infection spreading throughout the abdominal lining, without the appendix rupturing or forming a contained infection pocket.

Coding Tips

  • This code requires documentation of generalized peritonitis; ensure the clinical record confirms infection has spread beyond the appendix
  • Verify that perforation and abscess are both absent; if either is present, use a different K35.2 code
