Code Description

ICD-10 C82.12 is a billable code used to indicate a diagnosis of follicular lymphoma grade ii, intrathoracic lymph nodes.

Key Diagnostic Point:

Follicular lymphoma is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. Grade II indicates an intermediate level of aggressiveness, with a higher proliferation rate than grade I but lower than grade III. When this lymphoma affects the intrathoracic lymph nodes, it typically presents with symptoms such as lymphadenopathy, which may be accompanied by B-symptoms like fever, night sweats, and weight loss. Diagnosis is often confirmed through biopsy and histological examination, which reveals the characteristic follicular architecture. Staging is crucial for treatment planning and involves imaging studies such as CT scans or PET scans to assess the extent of disease spread. Treatment options may include watchful waiting for asymptomatic patients, chemotherapy, immunotherapy, or radiation therapy, depending on the stage and symptoms. The prognosis varies based on the stage at diagnosis and the patient's overall health.
