S31.136Puncture wound of abdominal wall without foreign body, right flank without penetration into peritoneal cavity

S31.136 is the ICD-10-CM diagnosis code for puncture wound of abdominal wall without foreign body, right flank 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 3 subcodes must be used instead.

Within S31.13, choose S31.136 (right flank without penetration into peritoneal cavity) only when documentation doesn't support a more specific option: right upper quadrant without penetration into peritoneal cavity (S31.130), left upper quadrant without penetration into peritoneal cavity (S31.131), epigastric region without penetration into peritoneal cavity (S31.132), right lower quadrant without penetration into peritoneal cavity (S31.133), left lower quadrant without penetration into peritoneal cavity (S31.134), periumbilic region without penetration into peritoneal cavity (S31.135), left flank without penetration into peritoneal cavity (S31.137), unspecified quadrant without penetration into peritoneal cavity (S31.139) and 1 more.

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.
