Non-follic lymphoma, unsp, extrnod and solid organ sites

This code signifies a malignant lymphoma that does not originate from follicular centers and is found outside of the lymphatic system, affecting solid organs or other extranodal sites. The specific type of non-follicular lymphoma is not identified in the pathology report.

Use this code when documentation confirms a diagnosis of diffuse lymphoma, explicitly stating it is extranodal or affecting a solid organ, but the specific histological subtype (e.g., DLBCL, peripheral T-cell lymphoma) is not yet determined or specified. This is often an interim diagnosis or used when pathology is inconclusive regarding the exact subtype.

• Ensure documentation clearly states "extranodal" or specifies a solid organ site.
• Avoid using this code if a more specific subtype of non-follicular lymphoma (e.g., C83.3- for diffuse large B-cell lymphoma) is identified.
• Always query the provider for a more definitive diagnosis if the pathology report is incomplete or ambiguous.
