About 42810: Superficial branchial cleft remnant excision
Reports removal of a superficial branchial cleft cyst or remnant confined to the skin and subcutaneous tissue, without deeper extension.
This code describes surgical removal of a branchial cleft cyst or remnant when it is limited to the skin and tissue just beneath it. Otolaryngologists and other surgeons may perform the procedure for a congenital neck lump or draining opening attributable to a superficial branchial cleft remnant. The operative report should identify the lesion and its location and show that its extent remained within the skin and subcutaneous tissues.
Choose this code based on the documented depth and extent, not simply the diagnosis of a neck cyst. A remnant extending deeper than the subcutaneous tissues or into the pharynx points to 42815 instead. The procedure has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral procedures, modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeons and team surgery are not permitted.
