Question:

CS Extension/CS Mets at Dx--Corpus uteri: Is a microscopic metastasis in a cul-de-sac implant more appropriately reflected in the CS Extension field code 80 [Further contiguous extension; cul-de-sac] or in the CS Mets at Dx field code 40 [Distant metastasis]?

Discussion:

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 code 80 [Further contiguous extension; Cul de sac] for CS extension in this case. Endometrium and ovary are exceptions to the rules that only contiguous extension is coded in Extension code 80. Only true distant metastases are coded in Mets at Dx.
