Benign neoplasm of ear and external auditory canal

This code represents a non-cancerous growth originating from the tissues of the ear, including the auricle and the external auditory canal. These benign neoplasms are typically localized and do not metastasize.

Assign this code when documentation clearly indicates a benign tumor, such as an osteoma, chondroma, or papilloma, affecting the external ear or ear canal. Supporting documentation includes pathology reports confirming benign status or physician notes describing a non-malignant lesion.

• Differentiate carefully between benign and malignant neoplasms; a different code series applies for malignancy.
• Ensure the documentation specifies the external ear or auditory canal, as other ear structures have distinct codes.
• Do not use for inflammatory polyps or cysts, which have separate classifications.
