Oth types of non-Hodgkin lymphoma, lymph nodes mult site

This code signifies a diagnosis of non-Hodgkin lymphoma that does not fit into more specific classifications, yet has distinct characteristics documented by the physician. It specifically indicates involvement of multiple lymph node regions throughout the body, rather than a single site or a disseminated extranodal presentation.

Use this code when the medical record clearly states a diagnosis of non-Hodgkin lymphoma that is not otherwise specified (NOS) but has unique features, and the disease is present in multiple lymph node sites. Documentation should specify "other specified types" of non-Hodgkin lymphoma and confirm multifocal lymph node involvement.

• Ensure the physician's documentation explicitly states "other specified types" of non-Hodgkin lymphoma, not just "unspecified."
• Verify that the medical record confirms involvement of multiple distinct lymph node regions.
• Distinguish from codes for single lymph node involvement or extranodal sites, even if multiple.
