Oth non-follic lymphoma, extranodal and solid organ sites

This code signifies a malignant lymphoma that does not originate from follicular centers and is found in locations outside of the lymph nodes or in solid organs. It represents a diverse group of non-Hodgkin lymphomas with varying prognoses and treatment approaches, excluding those specifically classified elsewhere.

Use this code when documentation specifies a non-follicular lymphoma that is extranodal (e.g., gastrointestinal tract, skin, central nervous system) or involves a solid organ (e.g., liver, spleen, bone marrow). This code is appropriate when the specific subtype of non-follicular lymphoma is not otherwise specified or classifiable to a more precise code within the C83 category.

• Ensure the documentation clearly states "non-follicular" and specifies an extranodal or solid organ site.
• Avoid using this code if a more specific subtype of non-follicular lymphoma (e.g., mantle cell, diffuse large B-cell) is identified and has its own distinct code.
• Always review the pathology report for definitive diagnosis and site specificity to ensure accurate coding.
