K62.8Other specified diseases of anus and rectum

K62.8 is the ICD-10-CM diagnosis code for other specified diseases of anus and rectum. It belongs to category K62 (other diseases of anus and rectum), 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 K62, choose K62.8 (Other specified diseases of anus and rectum) only when documentation doesn't support a more specific option: anal polyp (K62.0), rectal polyp (K62.1), anal prolapse (K62.2), rectal prolapse (K62.3), stenosis of anus and rectum (K62.4), hemorrhage of anus and rectum (K62.5), ulcer of anus and rectum (K62.6), radiation proctitis (K62.7) and 1 more.

To report this condition, pick the subcode that matches the documentation: K62.81 ((old)), K62.82 (anus) and K62.89 (rectum).

The conditions in its Excludes2 note aren't part of K62.8, but may be coded alongside it if the patient has both: ulcerative proctitis (K51.2).

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