Question:

CS Site Specific Factor--Colon: If the patient has a polypectomy followed by definitive surgery, can a higher CEA reported after the polypectomy but before the colon resection be coded?

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.If the tumor was in the polyp, do not use the post-polypectomy CEA even if it is higher than CEA's prior to the polypectomy. In this situation, the polypectomy would be treatment.

Conversely, if this is a frank adenocarcinoma or the tumor was so invasive that the polyp removed only a portion, use the post-polypectomy CEA because the polypectomy would not be treatment in this situation.
