Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Assign CS Extension code 20 [Invasion of subcutaneous tissue...] based on the final diagnosis on the path report. There is "dermal lymphatic invasion in nipple." In this case, the stage will be determined by the tumor size.
