Melanocytic nevi of unsp upper limb, including shoulder

This code represents the presence of a melanocytic nevus, commonly known as a mole, located anywhere on the upper limb, including the shoulder, when the specific location within the upper limb is not documented. These are benign proliferations of melanocytes, typically appearing as pigmented skin lesions.

Use this code when documentation confirms a melanocytic nevus on the upper limb or shoulder, but the precise anatomical site (e.g., forearm, upper arm, hand) is not specified. This code is appropriate for initial diagnosis, follow-up, or before excision of such a lesion when the exact location is unknown or not recorded.

• Avoid using this code if a more specific anatomical site on the upper limb (e.g., D22.61 for right upper limb, D22.62 for left upper limb) is documented.
• Ensure the documentation clearly states "unspecified" or lacks further detail regarding laterality or specific location within the upper limb.
• Do not use for malignant melanoma (C43.-) or dysplastic nevi (D48.5).
