Benign neoplasm of skin of trunk, except scrotum

This code represents a non-cancerous growth originating from the skin or subcutaneous tissue located on the torso, excluding the scrotal area. These benign neoplasms are typically slow-growing and do not metastasize. Examples include benign moles, skin tags, or lipomas found on the back, chest, abdomen, or flanks.

Use this code when documentation clearly identifies a benign skin lesion on the trunk, such as a nevus, dermatofibroma, or sebaceous cyst, and explicitly rules out malignancy. This code is appropriate for initial diagnosis, follow-up, or excision of such lesions. Supporting documentation includes pathology reports confirming benignity or physician notes describing a clinically benign appearance.

• Ensure the documentation specifies "benign" and the anatomical site is clearly on the trunk, excluding the scrotum.
• Differentiate from malignant neoplasms of the skin (172.x, 173.x) and uncertain behavior neoplasms (238.2).
• If the lesion is excised, link this diagnosis to the appropriate CPT code for excision of skin lesions.
