Billable

Noninflammatory disorder of vulva and perineum, unspecified

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A non-infectious condition affecting the external female genitalia or the area between the genitals and anus, where the specific type is not identified.

Coding Tips

  • Use this code only when the specific noninflammatory disorder cannot be determined; review documentation for more specific diagnoses like vulvodynia or lichen sclerosus
  • Ensure the condition is confirmed as noninflammatory to avoid confusion with inflammatory vulvovaginitis codes (N76.x)
