S36.490Other injury of duodenum

S36.490 is the ICD-10-CM diagnosis code for other injury of duodenum. 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 3 subcodes must be used instead.

Within S36.49 (other injury of small intestine), S36.490 is specifically for other injury of duodenum. Related codes cover other part of small intestine (S36.498) and unspecified part of small intestine (S36.499).

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.
