Benign neoplasm of eyelid, including canthus

This code signifies a non-cancerous growth originating from the tissues of the eyelid, including the inner or outer corner (canthus) of the eye. These lesions are typically slow-growing and do not metastasize, but may require removal due to cosmetic concerns, irritation, or obstruction of vision.

Apply this code when documentation clearly identifies a benign tumor or mass located on any part of the eyelid or canthus. This includes common benign lesions such as papillomas, nevi, or sebaceous cysts of the eyelid. Supporting documentation should specify the benign nature of the growth, often confirmed by biopsy or clinical assessment.

• Differentiate carefully between benign and malignant eyelid neoplasms; malignant lesions are coded to the 173.1 series.
• Avoid using this code for inflammatory conditions or cysts not explicitly identified as neoplastic, such as chalazion or styes.
• Ensure the physician's documentation specifies "benign" or provides pathology results confirming the non-malignant nature of the eyelid lesion.
