N81 — Female genital prolapse

Non-billable headerICD-10-CM

N81 is a non-billable header ICD-10-CM code for female genital prolapse. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

genital prolapse complicating pregnancy, labor or delivery (O34.5-)
prolapse and hernia of ovary and fallopian tube (N83.4-)
prolapse of vaginal vault after hysterectomy (N99.3)

Other codes that can never be billed with N81

These codes carry an Excludes1 note pointing at N81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N81 alone.

N36.8Other specified disorders of urethra
N81.0Urethrocele
N81.1Cystocele
N81.2Incomplete uterovaginal prolapse
N81.5Vaginal enterocele
N81.6Rectocele
N85Other noninflammatory disorders of uterus, except cervix
N89.8Other specified noninflammatory disorders of vagina

Risk adjustment

N81 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead N81

9 child codes. Green means billable.
