ICD-10 Code L29.9 – Pruritus, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L29.9 – Pruritus, unspecified
What it is
L29.9 identifies itching when the cause or site is not specified. Use it for nonspecific pruritus documented without a clearer diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record notes generalized or localized itching, scratching, or skin irritation, without a confirmed underlying cause.
When to use this code
Use L29.9 when the clinician documents pruritus and does not identify a more specific type, cause, or body site. It also fits cases where itching is the main problem but the chart lacks enough detail for a more precise code.
Do not use for
Do not use this code if the record specifies a cause such as dermatitis, urticaria, or another diagnosed skin disorder. Check documentation when itching is limited to a defined site or linked to another condition.
Coding tip
Before assigning L29.9, look for a documented underlying diagnosis or anatomic location that may support a more specific code.
