About S31.815

S31.815 is the ICD-10-CM diagnosis code for open bite of right buttock. 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 S31.81 (open wound of right buttock), S31.815 is specifically for open bite of right buttock. Related codes cover laceration without foreign body of right buttock (S31.811), laceration with foreign body of right buttock (S31.812), puncture wound without foreign body of right buttock (S31.813), puncture wound with foreign body of right buttock (S31.814) and unspecified open wound of right buttock (S31.819).

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 S31.815 together with the conditions in its Excludes1 note: superficial bite of buttock (S30.870).

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