I excised a skin lesion and the pathology came back as a giant pigmented nevus. ICD-9 says this is “uncertain behavior,” 238.2. Which CPT code do I use – malignant (116xx) or benign (114xx)?
Great question! It is most appropriate to use the excision of benign skin lesion CPT code (114xx) for excision of uncertain behavior skin lesions.
