ICD-10 Code L82.0 – Inflamed seborrheic keratosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L82.0 – Inflamed seborrheic keratosis
What it is
L82.0 identifies a seborrheic keratosis that is inflamed. It is a benign skin growth with irritation or inflammation noted in the diagnosis.
Clinical signs
Clinical features vary; refer to documentation. You may see a raised, waxy, or “stuck-on” lesion with redness, tenderness, or crusting when inflammation is present.
When to use this code
Use L82.0 when the provider documents an inflamed seborrheic keratosis, including a lesion described as irritated, reddened, or inflamed. Code this when the note clearly identifies the keratosis itself, not just a nonspecific skin lesion. Check documentation if the record only says “seborrheic keratosis” without inflammation.
Do not use for
Do not use this code for ordinary, non-inflamed seborrheic keratosis. Avoid it when the diagnosis is uncertain or when another benign or malignant skin lesion is documented instead.
Coding tip
Code L82.0 only when inflammation is specifically documented; otherwise, use the more general seborrheic keratosis code.
