One of the reader questions in Dermatology Coding Alert, Vol. 5, No. 1, listed an incorrect CPT code. In "Biopsy one day, excision later = 2 procedures," the code should be 11100, not 11110 (which is a nonexistent code). The descriptor in the answer (Biopsy of skin, subcutaneous tissue and/or mucous membrane [including simple closure], unless otherwise listed; single lesion) is correct for 11100.
