Code Description

ICD-10 C82.18 is a billable code used to indicate a diagnosis of follicular lymphoma grade ii, lymph nodes of multiple sites.

Key Diagnostic Point:

Follicular lymphoma grade II is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. This malignancy typically presents in the lymph nodes but can also involve other extranodal sites. Grade II indicates an intermediate level of aggressiveness, with a higher proliferation rate than grade I but lower than grade III. Patients may present with painless lymphadenopathy, and the disease can be indolent or aggressive, necessitating careful evaluation. Staging is crucial, often utilizing the Ann Arbor system, which considers the number of lymph node regions involved and the presence of B-symptoms such as fever, night sweats, and weight loss. Treatment protocols may include watchful waiting for asymptomatic patients, chemotherapy, immunotherapy, or a combination of these, depending on the stage and symptoms. The prognosis varies, with factors such as age, performance status, and response to initial therapy influencing outcomes.

Frequently Asked Questions

What is the significance of grading in follicular lymphoma?

Grading in follicular lymphoma indicates the aggressiveness of the disease and helps guide treatment decisions. Grade II indicates an intermediate level of aggressiveness, which may require more intensive treatment compared to grade I.
