Mantle cell lymphoma, lymph nodes of head, face, and neck

This code signifies a diagnosis of mantle cell lymphoma (MCL) specifically affecting the lymph nodes located in the head, face, or neck regions. MCL is an aggressive, non-Hodgkin B-cell lymphoma characterized by the translocation t(11;14)(q13;q32).

Use this code when documentation confirms a pathological diagnosis of mantle cell lymphoma and explicitly states involvement of lymph nodes in the head, face, or neck. This is typically supported by biopsy results and imaging studies identifying affected lymph nodes in these anatomical areas.

• Ensure the documentation clearly specifies "mantle cell lymphoma" and not another subtype of non-Hodgkin lymphoma.
• Verify that the affected lymph nodes are explicitly located in the head, face, or neck; avoid using this code for generalized or unspecified lymph node involvement.
• Code any associated symptoms or complications separately, if applicable and supported by documentation.
