Melanocytic nevi of unsp ear and external auricular canal

This code signifies the presence of a benign pigmented lesion, specifically a melanocytic nevus, located on an unspecified ear or within the external auditory canal. These are common, non-cancerous skin growths resulting from a cluster of melanin-producing cells.

Apply this code when documentation indicates a melanocytic nevus on either the external ear or within the ear canal, and the specific laterality (right or left) is not documented. This is appropriate for initial diagnosis, follow-up, or when the lesion is incidentally noted.

• Do not use if laterality (right or left ear) is specified; instead, select a more specific D22.2- code.
• Ensure the documentation clearly identifies the lesion as a "nevus" or "mole" and specifies its location as the ear or external auditory canal.
• Distinguish from other benign skin lesions of the ear, such as seborrheic keratosis or skin tags, which have different ICD-10-CM codes.
