Other non-follicular lymphoma, lymph nodes of multiple sites

This code signifies a malignant lymphoma that does not originate from follicular centers, affecting multiple groups of lymph nodes throughout the body. It encompasses various rare or unspecified types of non-follicular lymphomas that are not classified elsewhere.

Use this code when documentation specifies a diagnosis of "other non-follicular lymphoma" or a similar unspecified non-follicular lymphoma, with involvement of lymph nodes in more than one region (e.g., cervical and inguinal). This code requires clear documentation of the lymphoma type as non-follicular and its multifocal lymph node involvement.

• Ensure the documentation explicitly states "non-follicular" and "multiple sites" for lymph node involvement.
• Do not use this code if a more specific type of non-follicular lymphoma (e.g., diffuse large B-cell lymphoma) is identified; instead, code to the specific type.
• Sequence this code as the primary diagnosis when the lymphoma is the reason for the encounter, followed by any associated complications or manifestations.
