Diffuse large B-cell lymph of extrnod and solid organ sites

This code signifies a diagnosis of diffuse large B-cell lymphoma (DLBCL) that originates in or has spread to extranodal sites other than those specifically classified elsewhere, or to solid organs. This aggressive non-Hodgkin lymphoma involves mature B-lymphocytes and can manifest in various locations outside of lymph nodes, bone marrow, or spleen.

Use this code when documentation specifies DLBCL affecting sites such as the gastrointestinal tract (excluding stomach or intestine specified elsewhere), central nervous system, skin, breast, or other solid organs not otherwise specified. The medical record should clearly indicate the extranodal or solid organ involvement and confirm the DLBCL subtype.

• Differentiate from DLBCL of lymph nodes (C83.30-C83.38) or spleen (C83.3A).
• Ensure the documentation specifies "diffuse large B-cell lymphoma" and the "other extranodal" or "solid organ" site.
• Code additional manifestations or complications of the lymphoma as appropriate.
