Reader Question:

Biopsy Versus Excision

Question: If a physician removes a lesion from the face for biopsy and sends it for pathology review, should I bill both 11440 and 11100?

Answer: The distinguishing factor here is whether the entire lesion is removed or a portion removed for identification. Use 11100 (biopsy of skin, subcutaneous tissue and/or mucous membrane [including simple closure], unless otherwise listed [separate procedure]; single lesion) for a biopsy when you just take a piece of the lesion for pathology. The code is for the procedure itself and would not be billed with 11440 (excision, other benign lesion [unless listed elsewhere], face, ears, eyelids, nose, lips, mucous membrane; lesion diameter 0.5 cm or less). Code 11440 would be used if you completely removed the lesion and then sent it for pathology.
