Benign neoplasm of appendix

This code represents a non-cancerous growth originating from the tissues of the appendix. These benign tumors are typically slow-growing and do not spread to other parts of the body. They are distinct from malignant (cancerous) neoplasms of the appendix.

Use this code when documentation clearly indicates a benign neoplasm of the appendix, often identified incidentally during imaging studies or appendectomy. Supporting documentation should specify the benign nature of the tumor, usually confirmed by pathology reports.

• Always review pathology reports to confirm the benign nature and specific location within the appendix.
• Do not use this code if the pathology report identifies a carcinoid tumor of the appendix; refer to the Excludes1 note.
• Ensure the documentation differentiates between a benign neoplasm and an inflammatory condition of the appendix, such as appendicitis.
