malignant lesion of the neck
A pre-malignant lesion is a lesion that, while not cancerous, has strong potential for becoming cancerous. An example would be a callous-like area between the cheek and gum where someone who chews tobacco keeps the tobacco plug. Given enough time, that area will often turn cancerous. Sometimes a chronic irritation from an ill-fitting denture can be called pre-malignant. The cause of a pre-malignant lesion should be determined and eliminated, and the lesion should usually be biopsied to make sure it is not cancer.
The CPT code for the excision of a malignant lesion depends on the size and location of the lesions. For a 2.5 cm malignant lesion of the lip, you would typically use 14040 (excision, malignant lesion, lip). For the two malignant lesions on the chest, you would use codes such as 11602 (excision, malignant lesion, chest, excised diameter of 1.1 cm to 2.0 cm) or 11603 (excised diameter of 2.1 cm to 3.0 cm), depending on their sizes. Accurate coding may require specific details about the lesions and excised margins.
