About N90.8

N90.8 is the ICD-10-CM diagnosis code for other specified noninflammatory disorders of vulva and perineum. It belongs to category N90 (other noninflammatory disorders of vulva and perineum), 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 2 subcodes must be used instead.

Within N90, choose N90.8 (Other specified noninflammatory disorders of vulva and perineum) only when documentation doesn't support a more specific option: mild vulvar dysplasia (N90.0), moderate vulvar dysplasia (N90.1), dysplasia of vulva, unspecified (N90.3), leukoplakia of vulva (N90.4), atrophy of vulva (N90.5), hypertrophy of vulva (N90.6), vulvar cyst (N90.7) and noninflammatory disorder of vulva and perineum, unspecified (N90.9).

To report this condition, pick the subcode that matches the documentation: N90.81 (status) and N90.89 (perineum).

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