2026 ICD-10-CM Diagnosis Code C82.64 – Cutaneous follicle center lymphoma, lymph nodes of axilla and upper limb
What it is
C82.64 identifies cutaneous follicle center lymphoma involving lymph nodes of the axilla and upper limb. Use it when the record specifies this lymphoma subtype and anatomic location.
Clinical signs
Clinical features vary; refer to documentation. Records may describe persistent lymph node enlargement, skin-related lesions, or biopsy findings consistent with cutaneous follicle center lymphoma.
When to use this code
Use this code when the provider documents cutaneous follicle center lymphoma in axillary or upper-limb lymph nodes. It is appropriate for confirmed diagnoses, problem lists, and encounters focused on this specific site. Check documentation if the site or subtype is unclear.
Do not use for
Do not use it for other non-Hodgkin lymphomas, unspecified lymphoma, or skin lesions without a confirmed lymphoma diagnosis. If the record does not specify axilla or upper limb, check documentation.
Coding tip
Verify both the lymphoma subtype and the involved lymph node region before assigning C82.64.
