S36.5Injury of colon

S36.5 is the ICD-10-CM diagnosis code for injury of colon. It belongs to category S36 (injury of intra-abdominal organs), block S30-S39 (injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within S36 (injury of intra-abdominal organs), S36.5 is specifically for injury of colon. Related codes cover spleen (S36.0), liver and gallbladder and bile duct (S36.1), pancreas (S36.2), stomach (S36.3), small intestine (S36.4), rectum (S36.6), other intra-abdominal organs (S36.8) and unspecified intra-abdominal organ (S36.9).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

The conditions in its Excludes2 note aren't part of S36.5, but may be coded alongside it if the patient has both: injury of rectum (S36.6-).

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