CPT® code 15786 is used for abrasion treatment of a single lesion (e.g., for keratosis) through techniques like dermabrasion (lightly sanding the skin ' s surface). When treating multiple lesions in this manner, each lesion treated should be coded individually.
Since the patient has 5 keratosis lesions treated through sanding, 15786 x 5 accurately represents the procedure for each lesion.
Explanation of other options:
A. 15787 x 5: Incorrect because 15787 is designated for dermabrasion of " additional lesions " and would be used in conjunction with 15786, not alone.
B. 15786, 15787: Incorrect, as it does not account for all five lesions treated.
C. 15786, 15787 x 4: Incorrect, as 15787 is used only when performed in addition to 15786, not as a replacement for each additional lesion.
Therefore, the correct answer is D. 15786 x 5, which accurately reports the treatment of all five lesions.
