Diffuse follicle center lymphoma, lymph nodes mult site

This code signifies a diagnosis of diffuse follicle center lymphoma, a type of non-Hodgkin lymphoma, that has spread to or originated in multiple lymph node regions throughout the body. It indicates a more widespread presentation of this specific B-cell lymphoma.

Apply this code when documentation explicitly states diffuse follicle center lymphoma affecting multiple lymph node sites. This diagnosis is typically confirmed by biopsy and pathology reports. Use when the physician's final diagnosis specifies both the histological subtype and the multi-site involvement of lymph nodes.

• Ensure the pathology report confirms "diffuse follicle center lymphoma" and not another subtype of follicular lymphoma or diffuse large B-cell lymphoma.
• Verify that documentation specifies involvement of "multiple sites" or clearly lists involvement in more than one distinct lymph node region.
• Do not use if the lymphoma is localized to a single lymph node region or if the histological subtype is not precisely diffuse follicle center.
