Diffuse follicle center lymphoma, unspecified site

This code signifies a diagnosis of diffuse follicle center lymphoma, a specific subtype of non-Hodgkin lymphoma characterized by a diffuse growth pattern and follicular center cell morphology. It indicates that the primary anatomical site of the lymphoma has not been specified in the medical record.

Use this code when the physician's documentation confirms a diagnosis of diffuse follicle center lymphoma, but the exact location (e.g., lymph nodes, extranodal sites) is not documented or is unknown. This code is appropriate when the pathology report specifies "diffuse follicle center lymphoma" without further site detail.

• Do not use this code if a specific anatomical site for the diffuse follicle center lymphoma is documented; instead, use a more specific code from the C82.5 series.
• Always review the pathology report and physician's notes for any mention of the primary site to ensure the most specific code is selected.
• This code is for the diagnosis of the lymphoma itself; codes for associated symptoms or complications should be reported separately.
