Questions About N90Overview

What is the ICD-10 code for other noninflammatory disorders of vulva and perineum?

N90 is the ICD-10-CM category for other noninflammatory disorders of vulva and perineum, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is N90 (Other noninflammatory disorders of vulva and perineum) a billable code?

No. This is a category header that groups the codes for other noninflammatory disorders of vulva and perineum, and headers cannot be submitted on claims. Claims for other noninflammatory disorders of vulva and perineum need a more specific code from this category, such as N90.0, N90.1, and N90.3.

Can N90 be reported with A63.0?

Not as a rule. The Excludes1 note on N90 lists "anogenital (venereal) warts (A63.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
