About S39.021

S39.021 is the ICD-10-CM diagnosis code for laceration of muscle, fascia and tendon of abdomen. It belongs to category S39 (other and unspecified injuries 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 S39.02 (laceration of muscle, fascia and tendon of abdomen, lower back and pelvis), S39.021 is specifically for laceration of muscle, fascia and tendon of abdomen. Related codes cover lower back (S39.022) and pelvis (S39.023).

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.
