S39.9Unspecified injury of abdomen, lower back, pelvis and external genitals

S39.9 is the ICD-10-CM diagnosis code for unspecified injury of abdomen, lower back, pelvis and external genitals. 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 4 subcodes must be used instead.

Within S39, choose S39.9 (Unspecified injury of abdomen, lower back, pelvis and external genitals) only when documentation doesn't support a more specific option: injury of muscle, fascia and tendon of abdomen, lower back and pelvis (S39.0) and other specified injuries of abdomen, lower back, pelvis and external genitals (S39.8).

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.
