Nevus, non-neoplastic

This code describes a non-cancerous, non-vascular birthmark or skin lesion that is not further specified as a melanocytic, blue, or other specific type of nevus. It represents a benign skin anomaly present at birth or developing early in life, distinct from neoplastic growths.

Use this code when documentation clearly states "nevus, non-neoplastic" without further specificity regarding its cellular origin (e.g., melanocytic) or vascular nature. It is appropriate for benign nevi that do not fall into the categories of melanocytic or vascular malformations.

• Always review documentation for specific nevus types (e.g., blue, melanocytic, vascular) as these have more specific codes in D22.- or Q82.5.
• Avoid using this code if the nevus is described as "vascular" or "NOS" (not otherwise specified) as these direct to Q82.5 or D22.- respectively.
• Ensure the physician's documentation explicitly rules out a neoplastic process to support "non-neoplastic."
