Melanocytic nevi of scalp and neck

This code identifies the presence of benign, pigmented skin lesions, commonly known as moles, located specifically on the scalp or neck. These nevi are characterized by an accumulation of melanocytes, the cells responsible for producing skin pigment. They are typically harmless but may be monitored for changes in size, shape, or color.

Assign this code when documentation clearly indicates a diagnosis of a melanocytic nevus confined to the scalp or neck region. This applies to both newly identified nevi and those being monitored during follow-up visits. Supporting documentation should specify the anatomical location as either the scalp or neck.

• Do not use this code for congenital nevi; refer to codes in the Q82.5 category.
• Distinguish from atypical or dysplastic nevi, which have specific codes (e.g., D48.5).
• Ensure the documentation explicitly states "scalp" or "neck" to avoid using a less specific anatomical site code.
