S36.9Injury of unspecified intra-abdominal organ

S36.9 is the ICD-10-CM diagnosis code for injury of unspecified intra-abdominal organ. 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 4 subcodes must be used instead.

Within S36, choose S36.9 (unspecified intra-abdominal organ) only when documentation doesn't support a more specific option: spleen (S36.0), liver and gallbladder and bile duct (S36.1), pancreas (S36.2), stomach (S36.3), small intestine (S36.4), colon (S36.5), rectum (S36.6) and other intra-abdominal organs (S36.8).

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.

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