ICD-10 Code L29.0 – Pruritus ani (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L29.0 – Pruritus ani
What it is
Use this code for itching localized to the anal area. It describes a symptom diagnosis, not a cause such as hemorrhoids, dermatitis, or infection.
Clinical signs
Typical documentation includes anal itching, scratching, irritation, or discomfort around the anus. Clinical features vary; refer to documentation.
When to use this code
Assign L29.0 when the provider documents pruritus ani as the reason for the visit or as an active problem. Use it when the record identifies anal itching without a more specific underlying diagnosis. If another condition explains the itching, code that condition instead when documented.
Do not use for
Do not use this code for generalized pruritus or itching of other body sites. Do not use it when the chart documents a specific anal disorder that better explains the symptom.
Coding tip
Check the note for a documented cause, because L29.0 is often secondary to another confirmed diagnosis.
