Benign neoplasm of skin of lip

This code signifies a non-cancerous growth originating from the skin tissue of the lip. These benign lesions are typically slow-growing and do not metastasize to other parts of the body. They can include various types of benign tumors such as nevi, seborrheic keratoses, or fibromas located on the external lip surface.

Apply this code when documentation clearly indicates a benign neoplasm affecting the skin of the lip, confirmed by pathology or clinical assessment. This is appropriate for initial diagnosis, follow-up, or removal of such a lesion. Ensure the documentation specifies the benign nature and the lip as the anatomical site.

• Differentiate from malignant neoplasms of the lip (170-173 series) or benign neoplasms of other oral structures.
• Confirm the lesion is on the skin of the lip, not the vermilion border or internal mucosa, which would fall under other categories.
• Always seek pathology confirmation for definitive benign diagnosis if available.
