About N81.1

N81.1 is the ICD-10-CM diagnosis code for cystocele. It belongs to category N81 (female genital prolapse), block N80-N98 (noninflammatory disorders of female genital tract) 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.

Within N81 (female genital prolapse), N81.1 is specifically for cystocele. Related codes cover Urethrocele (N81.0), incomplete uterovaginal prolapse (N81.2), complete uterovaginal prolapse (N81.3), uterovaginal prolapse, unspecified (N81.4), vaginal enterocele (N81.5), rectocele (N81.6), other female genital prolapse (N81.8) and unspecified (N81.9).

To report this condition, pick the subcode that matches the documentation: N81.10 (unspecified), N81.11 (midline) and N81.12 (lateral).

Don't report N81.1 together with the conditions in its Excludes1 note: cystocele with prolapse of uterus (N81.2-N81.4).

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