Code Description

ICD-10 C82.50 is a billable code used to indicate a diagnosis of diffuse follicle center lymphoma, unspecified site.

Key Diagnostic Point:

Diffuse follicle center lymphoma (DFCL) is a subtype of non-Hodgkin lymphoma characterized by the proliferation of B-lymphocytes in the follicle center of lymphoid tissue. This condition is often classified under the broader category of follicular lymphomas, which are known for their indolent nature but can transform into more aggressive forms. DFCL typically presents with lymphadenopathy, which may be localized or generalized, and can involve extranodal sites. Patients may also exhibit B-symptoms, including fever, night sweats, and weight loss, which are indicative of systemic involvement. Diagnosis is confirmed through histopathological examination and immunophenotyping, revealing the presence of CD10, BCL6, and BCL2 markers. Treatment protocols often involve a combination of chemotherapy, immunotherapy, and, in some cases, radiation therapy, depending on the stage of the disease and the patient's overall health. Staging is crucial for determining the appropriate treatment approach and involves imaging studies and bone marrow biopsies to assess the extent of disease spread.
