About N71

N71 is the ICD-10-CM diagnosis code for inflammatory disease of uterus, except cervix. It belongs to block N70-N77 (inflammatory diseases of female pelvic organs) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N71.0 (uterus), N71.1 (uterus) and N71.9 (unspecified).

Don't report N71 together with the conditions in its Excludes1 note: hyperplastic endometritis (N85.0-) and infection of uterus following delivery (O85, O86.-).

Use an additional code (B95-B97), to identify infectious agent.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
