C82.5 is the ICD-10-CM diagnosis code for diffuse follicle center lymphoma. It belongs to category C82 (follicular lymphoma), block C81-C96 (malignant neoplasms of lymphoid, hematopoietic and related tissue) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 11 subcodes must be used instead.
