ICD-10 Code C82.6 – Cutaneous follicle center lymphoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.6 – Cutaneous follicle center lymphoma
What it is
C82.6 identifies cutaneous follicle center lymphoma, a low-grade B-cell lymphoma that primarily involves the skin. Use it when documentation specifies this skin-based follicular lymphoma diagnosis.
Clinical signs
Typical findings include one or more slowly growing skin nodules, plaques, or tumors, often on the head, neck, or trunk. Clinical features vary; refer to documentation.
When to use this code
Use C82.6 when the provider documents cutaneous follicle center lymphoma, primary cutaneous follicle center lymphoma, or a clearly equivalent diagnosis. It is appropriate when the record shows lymphoma limited to the skin or described as cutaneous. Check documentation if the site, subtype, or primary versus secondary involvement is unclear.
Do not use for
Do not use this code for nonspecific skin lesions, benign follicular disorders, or other lymphoma subtypes without explicit documentation. If the record does not confirm cutaneous follicle center lymphoma, check documentation.
Coding tip
Code the diagnosis only when the pathology or provider note clearly names the cutaneous follicle center lymphoma subtype.
