Melanocytic nevi of right ear and external auricular canal

This code signifies the presence of a benign pigmented lesion, commonly known as a mole, located specifically on the right ear or within its external auditory canal. These lesions are composed of melanocytes and are typically non-cancerous.

Use this code when documentation clearly identifies a melanocytic nevus (mole) on the patient's right ear, including the auricle or the canal leading to the eardrum. This code is appropriate for initial diagnosis, follow-up, or removal of such a lesion.

• Ensure the documentation specifies "right ear" or "right external auricular canal" to justify this laterality-specific code.
• Distinguish from other benign skin lesions of the ear (e.g., D23.21 for other benign neoplasms of skin of right ear).
• Do not use if the nevus is suspected to be malignant; instead, refer to codes in the C43 series for melanoma.
