About S37.50

S37.50 is the ICD-10-CM diagnosis code for unspecified injury of fallopian tube. 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 S37.5, choose S37.50 (Unspecified injury of fallopian tube) only when documentation doesn't support a more specific option: primary blast injury of fallopian tube (S37.51), contusion of fallopian tube (S37.52), laceration of fallopian tube (S37.53) and other injury of fallopian tube (S37.59).

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.
