What is the cpt code for incisional biopsy of mass?

The CPT code for an incisional biopsy of a mass is typically 11100. This code is used for an incisional biopsy of a skin lesion, but if the biopsy is performed on a different type of tissue, other codes may be more appropriate, such as 11101 for each additional lesion. Always verify the specific code based on the location and nature of the biopsy.
