ICD-10 Code L82 – Seborrheic keratosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L82 – Seborrheic keratosis
What it is
L82 identifies seborrheic keratosis, a common benign skin growth. It is used when the chart documents this noncancerous lesion by name.
Clinical signs
These lesions are usually well-circumscribed, waxy, and “stuck-on” in appearance. They may be tan, brown, or black, and can be flat or raised; clinical features vary, so refer to documentation.
When to use this code
Use L82 when the provider documents seborrheic keratosis, including single or multiple lesions. It is appropriate for routine dermatology visits, lesion checks, or excision notes when the diagnosis is clearly stated. If the record is unclear, check documentation.
Do not use for
Do not use L82 for malignant skin tumors, actinic keratosis, or other unspecified pigmented lesions. If the lesion type is not confirmed, check documentation before coding.
Coding tip
Code the documented diagnosis exactly; do not infer seborrheic keratosis from appearance alone.
