PT had a skin lesion on her anus which ended up being squamous carcinoma. Report states "excisional biopsy of perianal skin lesion" as the procedure. My first thought was 11100. But could I use 46922? I know this code falls under destruction, but it specifically also states surgical excision. Also, if the diagnosis is confirmed as malignant, then wouldn't the code be a skin lesion removal:malignant code, such as 11602? Which of these three would I use? Thanks for any help.
