Follicular lymphoma grade I, intra-abdominal lymph nodes

This code signifies a slow-growing type of non-Hodgkin lymphoma, specifically follicular lymphoma, that is classified as Grade I. The disease is located within the lymph nodes inside the abdominal cavity. This grade indicates a less aggressive form of the cancer.

Use this code when documentation confirms a diagnosis of follicular lymphoma, explicitly graded as Grade I, and the primary site of involvement is intra-abdominal lymph nodes. This diagnosis is typically established through biopsy and pathology reports. Ensure the physician's documentation clearly specifies both the grade and the intra-abdominal location.

• Always verify the grade of follicular lymphoma; different grades have distinct codes.
• Confirm the specific anatomical site of involvement; "intra-abdominal" is crucial for this code.
• Do not use this code if the documentation indicates a different grade (e.g., Grade II, III) or a different primary site of involvement.
