K63.0: Abscess of intestine

Clinical notes

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

abscess of intestine with Crohn's disease (K50.014, K50.114, K50.814, K50.914,)
abscess of intestine with diverticular disease (K57.0, K57.2, K57.4, K57.8)
abscess of intestine with ulcerative colitis (K51.014, K51.214, K51.314, K51.414, K51.514, K51.814, K51.914)

Excludes2 (not included here)

An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.

abscess of anal and rectal regions (K61.-)
abscess of appendix (K35.3-)
