Follicular lymphoma (C82)
ICD-10 code C82 represents follicular lymphoma, a type of non-Hodgkin lymphoma characterized by cancerous growth in lymphatic tissue. These codes are used to specify the grade and exact location of follicular lymphoma to ensure accurate diagnosis and treatment planning.
Follicular lymphoma codes cover various grades, from grade I to IIIb, reflecting the tumor's aggressiveness, including unspecified and remission statuses (e.g., C82.0 for grade I and C82.1A for grade II in remission). The subcodes detail lymphoma locations such as lymph nodes in the head, neck, axilla, intra-abdominal areas, or extranodal sites. Synonyms like "Follicular non-Hodgkin's lymphoma, small cleaved cell (clinical)" correspond to C82.00, aiding coders identifying the ICD-10 code for this condition. Other specialized types include diffuse follicle center lymphoma and cutaneous follicle center lymphoma, each with specific anatomical distinctions. Understanding these distinctions within the C82 series helps healthcare professionals capture the lymphoma's specific type and location for better clinical and administrative accuracy.

Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- follicular lymphoma with or without diffuse areas
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
