Anogenital pruritus, unspecified

This code signifies itching in the anogenital region, encompassing the perineum, anus, and external genitalia, without a more specific underlying cause identified. It represents a symptom rather than a definitive diagnosis of a specific dermatological or systemic condition.

This code is appropriate when a patient presents with anogenital itching, and the provider has not yet determined a specific etiology (e.g., fungal infection, contact dermatitis, pinworms, lichen sclerosus). It should be used when documentation indicates "anogenital pruritus, unspecified" or "itching of the perineum, NOS."

• Avoid using this code if a more specific cause for the pruritus is documented (e.g., candidiasis, contact dermatitis).
• Always review documentation for any mention of a specific site within the anogenital area or an underlying condition to allow for more precise coding.
• Consider sequencing this code as a secondary diagnosis if the primary reason for the encounter is related to investigation of the pruritus's cause.
