ICD-10 Code C82.61 – Cutaneous follicle center lymphoma, lymph nodes of head, face, and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.61 – Cutaneous follicle center lymphoma, lymph nodes of head, face, and neck
What it is
This code identifies cutaneous follicle center lymphoma involving lymph nodes in the head, face, or neck. It is used when documentation specifies this lymphoma site and nodal region.
Clinical signs
Clinical features vary; refer to documentation. You may see skin or nodal masses, enlarged lymph nodes, or biopsy findings consistent with follicle center lymphoma.
When to use this code
Use this code when the provider documents cutaneous follicle center lymphoma affecting lymph nodes of the head, face, or neck. It fits pathology-confirmed or clearly documented diagnoses for this anatomic site. Check documentation if the record only says “lymphoma” or does not specify the nodal region.
Do not use for
Do not use this code for other lymphoma types, unspecified lymphoma, or cutaneous lesions without documented follicle center lymphoma. If the involved site is different or unclear, check documentation.
Coding tip
Match the exact lymphoma subtype and nodal location in the pathology or provider note before assigning C82.61.
