Follicular lymphoma, unsp, lymph nodes of multiple sites

This code signifies a diagnosis of follicular lymphoma, a slow-growing type of non-Hodgkin lymphoma, when the specific subtype is not documented. It indicates that the disease is present in multiple lymph node regions throughout the body, without further specification of the exact sites.

Use this code when the medical record confirms a diagnosis of follicular lymphoma affecting multiple lymph node sites, but the pathologist or clinician has not specified the grade or a more precise subtype. This code is appropriate when documentation indicates widespread lymphadenopathy due to follicular lymphoma without further anatomical detail.

• Ensure documentation explicitly states "follicular lymphoma" and "multiple sites" or "widespread" lymph node involvement.
• Avoid using this code if a specific grade (e.g., grade I, II, III) or a more precise anatomical location of the affected lymph nodes is documented.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless another condition directly impacts the treatment of the lymphoma.
