K57.2Diverticulitis of large intestine with perforation and abscess

K57.2 is the ICD-10-CM diagnosis code for Diverticulitis of large intestine with perforation and abscess. It belongs to category K57 (Diverticular disease of intestine), block K55-K64 (other diseases of intestines) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within K57 (Diverticular disease of intestine), K57.2 is specifically for Diverticulitis of large intestine with perforation and abscess. Related codes cover Diverticulitis of small intestine with perforation and abscess (K57.0), Diverticular disease of small intestine without perforation or abscess (K57.1), Diverticular disease of large intestine without perforation or abscess (K57.3), Diverticulitis of both small and large intestine with perforation and abscess (K57.4), Diverticular disease of both small and large intestine without perforation or abscess (K57.5), Diverticulitis of intestine, part unspecified, with perforation and abscess (K57.8) and part unspecified, without perforation or abscess (K57.9).

To report this condition, pick the subcode that matches the documentation: K57.20 (without bleeding) and K57.21 (with bleeding).

Don't report K57.2 together with the conditions in its Excludes1 note: diverticulitis of both small and large intestine with perforation and abscess (K57.4-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
