Scar Revision
CPT Assistant, Fall 1993, Volume 03, Issue 3, pages 7-8
How are scar revisions coded? There may be several answers, depending upon what the physician does to the surgical defect created after removing the scar. To answer this question, scenarios will be presented along with the correct coding for each.
The "excision-benign lesions" codes (11400-11446) can be used to report the removal of a scar; these codes include simple closure of the wound created by the scar removal. Note that in the guidelines for use of these codes, cicatricial lesions are one of the examples given. Cicatricial means "pertaining to or resembling a scar". A hypertrophic scar is an example of a cicatricial lesion.
For example, Code 11401 would be reported if a 1 cm hypertrophic scar of the forearm was excised and the defect was closed with a simple repair.
11400Excision, benign lesion, except skin tag (unless listed elsewhere), trunk, arms or legs; lesion diameter 0.5 cm or less
11401lesion diameter 0.6 to 1.0 cm
Many times when revising a scar, a defect is created. Scar revision requiring more than simple closure is reported using a repair code, selected by the type of repair performed and the extent of the scarring.
For example, a 3 cm scar (in length) on the cheek is excised. The defect created by the scar excision is now 6 cm and cannot be closed primarily without extensive undermining of tissue in all directions; the repair performed requires more than layered closure and results in a 6 cm linear closure. This repair is coded as 13132 only. No code for lesion excision is reported. Instruction # 1, page 102 of CPT 1993 states... "The repaired wound(s) should be measured and recorded in centimeters, whether curved or stellate." The wound being repaired in this example is 6 cm long and is therefore coded using 13132.
Hope this helps
