About S37.409

S37.409 is the ICD-10-CM diagnosis code for unspecified injury of ovary, unspecified. It belongs to category S37 (injury of urinary and pelvic organs), 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 S37.40, choose S37.409 (unspecified) only when documentation doesn't support a more specific option: unilateral (S37.401) and bilateral (S37.402).

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.
