Non-Hodgkin lymphoma, unsp, lymph nodes of multiple sites

This code signifies a diagnosis of non-Hodgkin lymphoma where the specific type of lymphoma is not documented, and the disease has spread to or originated in multiple lymph node regions. It indicates a systemic involvement of the lymphatic system by an undifferentiated non-Hodgkin lymphoma.

Use this code when the medical record explicitly states "non-Hodgkin lymphoma, unspecified type" with involvement of multiple lymph node sites, and no further specificity regarding the lymphoma subtype is available. This code is appropriate when the physician has not yet determined the exact histological classification of the non-Hodgkin lymphoma or when the documentation is insufficient to assign a more specific code.

• Avoid using this code if a more specific type of non-Hodgkin lymphoma (e.g., follicular, diffuse large B-cell) is documented.
• Ensure documentation clearly indicates involvement of "multiple sites" or "generalized" lymphadenopathy due to lymphoma.
• Query the provider for greater specificity regarding the lymphoma type and primary site if possible, to allow for a more precise code assignment.
