K57.8 vs K63.0
K57.8 (Diverticulitis of intestine, part unspecified, with perforation and abscess) compared with K63.0 (Abscess of intestine), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. K63.0 carries an Excludes1 note covering K57.8: “abscess of intestine with diverticular disease (K57.0, K57.2, K57.4, K57.8)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
