Other types of follicular lymphoma, intrapelvic lymph nodes

This code signifies a diagnosis of follicular lymphoma that does not fit into the more common categories (e.g., grade I, II, III) and is specifically located within the intrapelvic lymph nodes. It indicates a less common or unspecified variant of follicular lymphoma affecting lymph nodes situated within the pelvic cavity.

Use this code when documentation specifies follicular lymphoma of an "other" or "unspecified" type, and the primary site of involvement is clearly identified as the intrapelvic lymph nodes. This applies when pathology reports confirm follicular lymphoma but do not provide a specific grade (e.g., grade 1, 2, 3) or subtype, and imaging or surgical reports localize the disease to the intrapelvic region.

• Ensure documentation explicitly states "follicular lymphoma" and specifies "intrapelvic lymph nodes" as the site.
• Do not use this code if a specific grade (e.g., grade I, II, III) of follicular lymphoma is documented; use the more specific code for that grade.
• Verify that the lymphoma is primary to the intrapelvic nodes, not metastatic from another site.
