ICD-10 Code L29 – Pruritus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L29 – Pruritus
What it is
L29 identifies pruritus, which means itching. Use it when the record documents itching as the main reason for care or as a significant diagnosis.
Clinical signs
Patients may report an urge to scratch, with or without visible skin changes. Clinical features vary; refer to documentation.
When to use this code
Use L29 when the provider documents pruritus without a more specific underlying diagnosis. It may apply to generalized itching or itching of an unspecified cause. If the note identifies a separate condition causing the itch, code that condition first when appropriate.
Do not use for
Do not use L29 for localized itching that is better described by a more specific code, or when the itching is clearly part of another documented disorder. Check documentation.
Coding tip
Code the documented cause of itching when available; use L29 only when pruritus is the documented diagnosis.
