S31.10Unspecified open wound of abdominal wall without penetration into peritoneal cavity

S31.10 is the ICD-10-CM diagnosis code for unspecified open wound of abdominal wall without penetration into peritoneal cavity. It belongs to category S31 (open wound of abdomen, lower back, pelvis and external genitals), 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 10 subcodes must be used instead.

Within S31.1, choose S31.10 (Unspecified open wound of abdominal wall without penetration into peritoneal cavity) only when documentation doesn't support a more specific option: laceration without foreign body of abdominal wall without penetration into peritoneal cavity (S31.11), laceration with foreign body of abdominal wall without penetration into peritoneal cavity (S31.12), puncture wound of abdominal wall without foreign body without penetration into peritoneal cavity (S31.13), puncture wound of abdominal wall with foreign body without penetration into peritoneal cavity (S31.14) and open bite of abdominal wall without penetration into peritoneal cavity (S31.15).

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.
