ICD-10 Code L82.1 – Other seborrheic keratosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L82.1 – Other seborrheic keratosis
What it is
L82.1 identifies a benign seborrheic keratosis that does not fit another specified type. You use it for a common, noncancerous skin growth when documentation supports this exact diagnosis.
Clinical signs
These lesions are usually well-defined, waxy or “stuck-on” papules or plaques with variable color and surface texture. Clinical features vary; refer to documentation.
When to use this code
Use L82.1 when the provider documents “other seborrheic keratosis,” “seborrheic keratosis NOS,” or an equivalent nonspecific benign keratosis. Apply it when the note clearly distinguishes the lesion from actinic keratosis, irritated seborrheic keratosis, or other coded variants.
Do not use for
Do not assign this code for actinic keratosis, skin tags, or lesions documented as irritated or inflamed seborrheic keratosis unless the record supports L82.1. Check documentation if the diagnosis is uncertain.
Coding tip
Code from the provider’s exact wording, and query if the lesion type is described only as “keratosis” without a seborrheic diagnosis.
