Other specified hypertrophy of vulva

This code describes an abnormal enlargement or overgrowth of the vulvar tissues that is not otherwise specified as hypertrophy of the clitoris or labia. It encompasses various forms of vulvar tissue overdevelopment beyond typical anatomical variations.

Use this code when documentation indicates hypertrophy of the vulva, but the specific anatomical structure (e.g., clitoris, labia majora/minora) is not precisely identified, or the hypertrophy affects other specified vulvar components. Supporting documentation should clearly state "vulvar hypertrophy" or a similar phrase without further anatomical detail.

• Ensure the documentation specifies "vulva" and not a more specific vulvar structure if N90.69 is chosen.
• Differentiate from N90.61 (Hypertrophy of clitoris) and N90.62 (Hypertrophy of labia) when more specific anatomical detail is provided.
• Always query the provider for greater specificity if the documentation simply states "vulvar hypertrophy" and further detail might be available.
