Answer: According to Dorland's Medical Dictionary, a diffuse, large cell lymphoma is a type of non-Hodgkin's lymphoma composed of large cleaved and noncleaved cells in a diffuse pattern of infiltration; it is similar to the diffuse mixed variety and has an intermediate grade of malignancy.

Based on this definition, 200.70 (Large cell lymphoma; unspecified site, extranodal and solid organ sites) isn't your most accurate choice. Instead, report diagnosis 202.8x (Other malignant neoplasms of lymphoid and histiocytic tissue; other lymphomas). Code the fifth digit according to the neoplasm's location.
