About K60

K60 is the ICD-10-CM diagnosis code for fissure and fistula of anal and rectal regions. It belongs to 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K60.0 (fissure), K60.1 (fissure), K60.2 (unspecified), K60.3 (fistula), K60.4 (fistula) and K60.5 (fistula).

The conditions in its Excludes2 note aren't part of K60, but may be coded alongside it if the patient has both: abscess or cellulitis of anal and rectal regions (K61.-) and anal sphincter tear (healed) (nontraumatic) (old) (K62.81).

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