Quizplus · Accepted Answer

CPT code 11604 is used for excision of a benign lesion that is greater than 4.0 cm, while CPT code 11603 is used for excision of a benign lesion that is less than or equal to 4.0 cm. Since the three lesions are malignant, neither of these codes can be used. CPT code 11606 can be used for excision of a malignant lesion that is less than 4.0 cm, and CPT code 11642 can be used for excision of a malignant lesion that is greater than or equal to 4.0 cm. Therefore, the three codes that would be appropriate for excising the three malignant lesions are 11606 for the 1.6-cm lesion of the lip, 11603 for the 2.4-cm lesion of the leg, and 11642 for the 3.2-cm lesion of the back. The correct answer is B.
