Oth malignant neoplasm skin/ right lower eyelid, inc canthus

This code signifies a malignant tumor of the skin located on the right lower eyelid, specifically including the inner or outer corner (canthus) of the eye. This diagnosis refers to a primary cancer that is not a basal cell carcinoma, squamous cell carcinoma, or melanoma, but rather another specified type of skin malignancy.

Use this code when documentation clearly identifies a primary malignant neoplasm of the skin of the right lower eyelid, including the canthus, that is not otherwise specified as basal cell, squamous cell, or melanoma. This code is appropriate for diagnoses such as Merkel cell carcinoma, sebaceous carcinoma, or other rare skin malignancies in this specific anatomical location.

• Ensure the pathology report specifies a malignant neoplasm other than basal cell, squamous cell, or melanoma.
• Verify the laterality (right) and specific anatomical site (lower eyelid, including canthus) are explicitly documented.
• Do not use this code for benign neoplasms, carcinoma in situ, or secondary malignant neoplasms.
