Pruritus ani

This code signifies the symptom of itching specifically around the anus. It indicates discomfort and irritation in the perianal region, which can be acute or chronic. This condition is a symptom, not a definitive diagnosis of an underlying cause.

Use this code when documentation clearly states "pruritus ani" as the patient's chief complaint or a significant symptom. It is appropriate when the provider is treating the symptom itself or investigating its cause. Supporting documentation would include patient complaints of anal itching and physical exam findings consistent with perianal irritation.

• Always look for a more specific underlying cause if documented (e.g., hemorrhoids, fungal infection, pinworms).
• This code is for the symptom; if a definitive diagnosis for the cause of the pruritus ani is established, code the definitive diagnosis first, and this code may be used as a secondary diagnosis if the pruritus is still a significant clinical issue.
• Do not confuse with generalized pruritus (698.9) or other localized itching not specifically perianal.
