About S30.13

S30.13 is the ICD-10-CM diagnosis code for contusion of flank (latus) region. It belongs to category S30 (superficial injury 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 S30.1 (contusion of abdominal wall), S30.13 is specifically for contusion of flank (latus) region. Related codes cover abdominal wall (S30.11) and groin (S30.12).

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.
