Nevus, non-neoplastic

This code identifies a non-cancerous birthmark or mole that is not a tumor. These are benign skin lesions resulting from an overgrowth of melanocytes or other skin cells, present at birth or developing early in life. They are typically stable in appearance and do not exhibit malignant characteristics.

Apply this code for documentation of a benign nevus explicitly stated as non-neoplastic. This is appropriate when a dermatologist or other clinician has evaluated a skin lesion and confirmed its non-malignant nature, often through visual inspection or dermoscopy, without suspicion of atypical features.

• Differentiate from malignant melanoma (172.xx) or other benign neoplasms of the skin (216.xx).
• Ensure documentation clearly states "non-neoplastic" or "benign nevus" without any qualifiers suggesting malignancy or atypicality.
• Avoid using this code if there is any suspicion of dysplasia or malignancy; further investigation or a more specific code would be warranted.
