History:
For cases diagnosed 1998-2002: There must be at least a 1 cm margin of resection for surgical procedures described in codes 40 and 50.
Code 40 is used when there is a wide local excision or a "local" amputation of a digit, an ear, a lip, etc.
Code 50 is used when an extensive excision is done that removes regional tissue/organs such as an amputation of a leg, the removal of the skin (primary), deep muscle, bone, etc. A radical excision is not a common surgical procedure for skin cancers.
