Other types of follicular lymphoma, unspecified site

This code signifies a diagnosis of follicular lymphoma that does not fit into the more common categories (e.g., grades 1, 2, 3) and where the specific anatomical location of the lymphoma is not documented. It represents a less common or atypical presentation of follicular lymphoma.

Apply this code when the pathology report confirms follicular lymphoma, but the specific subtype is described as "other" or "unspecified," and the physician documentation does not indicate a primary site. This code is appropriate when the documentation lacks the detail to assign a more specific follicular lymphoma code.

• Ensure the documentation explicitly states "other types" or an equivalent phrase, and that no specific site is identified.
• Avoid using this code if a specific grade (e.g., grade 1, 2, 3) or a specific anatomical site is documented; instead, use the more precise C82.0-C82.7 series.
• Always review the complete pathology report and physician notes for any additional information that might allow for a more specific code assignment.
