About K63.8

K63.8 is the ICD-10-CM diagnosis code for other specified diseases of intestine. It belongs to category K63 (other diseases 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 3 subcodes must be used instead.

Within K63, choose K63.8 (Other specified diseases of intestine) only when documentation doesn't support a more specific option: abscess of intestine (K63.0), perforation of intestine (nontraumatic) (K63.1), fistula of intestine (K63.2), ulcer of intestine (K63.3), Enteroptosis (K63.4), polyp of colon (K63.5) and disease of intestine, unspecified (K63.9).

To report this condition, pick the subcode that matches the documentation: K63.81 (intestine), K63.82 (overgrowth) and K63.89 (intestine).

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