2025 ICD-10-CM code C82
Follicular lymphoma. Includes follicular lymphoma with or without diffuse areas.
Medical necessity is based on the presence of signs, symptoms, and diagnostic findings confirming follicular lymphoma. Treatment is medically necessary when indicated based on staging and disease progression.
Diagnosis involves physical examination, lymph node biopsy, blood tests (CBC, LDH, kidney and liver function tests), and imaging studies (CT, PET). Treatment varies depending on the stage and may include watchful waiting, radiation therapy, or chemotherapy.
In simple words: Follicular lymphoma is a slow-growing blood cancer that affects the lymph nodes. It happens when white blood cells that fight infection become abnormal and multiply. It is a type of non-Hodgkin lymphoma.
Follicular lymphoma is a slow-growing subtype of non-Hodgkin lymphoma (NHL). It develops from abnormal B-cell lymphocytes, which are white blood cells that help fight infection. These abnormal cells multiply and collect in the lymph nodes, forming nodular clusters (follicles).
Example 1: A patient presents with painless, swollen lymph nodes in the neck. Biopsy reveals follicular lymphoma., A patient with fatigue and night sweats undergoes a PET scan, which reveals follicular lymphoma in multiple lymph node groups., A patient with a known history of follicular lymphoma is monitored with regular blood tests and imaging.
Documentation should include biopsy results, blood test findings, imaging reports, and clinical notes detailing symptoms, stage, and treatment plan.
