Melanocytic nevi, unspecified

This code represents a benign proliferation of melanocytes, commonly known as a mole, when its specific type or location is not documented. These lesions are typically small, pigmented skin growths that can vary in color, shape, and size. They are generally harmless but are routinely monitored for changes that might indicate malignancy.

Use this code when the medical record documents the presence of a melanocytic nevus without further specification of its type (e.g., intradermal, junctional, compound) or its anatomical site. This is appropriate for general screening or follow-up visits where a mole is noted but not further characterized. Documentation supporting its use would include "mole," "nevus," or "pigmented lesion" without additional detail.

• Avoid using this code if the nevus type or anatomical location is specified; instead, use a more specific D22 subcategory.
• Do not use this code for congenital nevi (Q82.5) or dysplastic nevi (D48.5).
• If a nevus is suspicious for malignancy, code the appropriate melanoma or atypical nevus code, or a symptom code like R21 (rash and other nonspecific skin eruption) if biopsy results are pending.
