Question:

Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)?

Discussion:

Answer:

For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed.

History:

For cases diagnosed 1998-2002: Code the Surgery of Primary Site field to 20 [Partial resection].
