S31.65Open bite of abdominal wall with penetration into peritoneal cavity

S31.65 is the ICD-10-CM diagnosis code for open bite of abdominal wall with 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 S31.6 (open wound of abdominal wall with penetration into peritoneal cavity), S31.65 is specifically for open bite of abdominal wall with penetration into peritoneal cavity. Related codes cover unspecified open wound of abdominal wall with penetration into peritoneal cavity (S31.60), laceration without foreign body of abdominal wall with penetration into peritoneal cavity (S31.61), laceration with foreign body of abdominal wall with penetration into peritoneal cavity (S31.62), puncture wound without foreign body of abdominal wall with penetration into peritoneal cavity (S31.63) and puncture wound with foreign body of abdominal wall with penetration into peritoneal cavity (S31.64).

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.

Don't report S31.65 together with the conditions in its Excludes1 note: superficial bite of abdominal wall (S30.861, S30.871).

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