Post Op: Ulcerative Neoplasm, left neck-nonhealing

Procedure: Excision of tumor of left neck, CPT 21556

In the description the physician dictates that a full-thickness excision was carried out down through the platysma muscle and to involve the underlying subplatysmal fat. The entire lesion was excised with a grossly normal appearing margin of skin around the ulcerative neoplasm site. Undermining was carried out at the wound edges and then the wound was closed using a multilayer wound closure technique.

The path states: skin, left neck, Excisional biopsy- dx: shallow ulcer and granulation tissue, benign.

The physician dictates he excised through the platysma muscle, but the path reads skin. Should the 114xx codes should be used in this case with intermediate repair? Thank everyone for any input!!
