Oth types of foliclar lymph, nodes of axilla and upper limb

This code represents a specific subtype of follicular lymphoma that does not fit into the more common categories (e.g., grade 1, 2, 3) and is specifically located in the lymph nodes of the axilla and/or upper limb. Follicular lymphoma is a slow-growing non-Hodgkin lymphoma originating from B-lymphocytes.

Use this code when documentation clearly specifies a diagnosis of "other types" of follicular lymphoma, meaning it's not otherwise specified as grade 1, 2, or 3, and the primary site of involvement is the axillary or upper limb lymph nodes. Pathological reports confirming the follicular lymphoma subtype and its specific anatomical location are essential for accurate coding.

• Ensure the documentation specifies "other types" of follicular lymphoma, not just follicular lymphoma NOS or a specific grade.
• Verify the anatomical site is explicitly stated as axillary or upper limb lymph nodes.
• Do not use this code if the follicular lymphoma is specified as grade 1, 2, or 3, even if in the axilla/upper limb; use the appropriate C82.0-C82.2 codes instead.
