ICD-10 Code L29.3 – Anogenital pruritus, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L29.3 – Anogenital pruritus, unspecified
What it is
L29.3 identifies itching of the anogenital region when the cause is not further specified. Use it for pruritus involving the anus, genital area, or both when documentation does not name a more specific condition.
Clinical signs
Typical documentation includes persistent itching, scratching, irritation, or excoriation in the anogenital area. Clinical features vary; refer to documentation if the record also mentions rash, discharge, infection, or another defined diagnosis.
When to use this code
Use this code when the provider documents anogenital pruritus, pruritus ani, or similar itching symptoms without a more specific etiology. It also fits when the note states itching in the perineal, anal, or genital region and no other diagnosis is established.
If the chart identifies a causative condition, code that condition instead of the symptom when appropriate. Check documentation when itching is part of a broader skin, infectious, or inflammatory disorder.
Do not use for
Do not use L29.3 for generalized pruritus or itching limited to another body site. Do not assign it when the record clearly supports a specific underlying diagnosis that better explains the symptom.
Coding tip
Query for the exact site and cause of itching before defaulting to this unspecified symptom code.
