Question:

EOD-Extension--Corpus Uteri: What code is used to represent this field for a corpus primary (sounding 8 cm or less in length) treated with radiation prior to a hysterectomy that pathologically showed superficial myometrial invasion? Is it possible that the invasion could have been more extensive prior to the radiation treatment?

Discussion:

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 12 [Myometrium, inner half] which represents the extension you know. In this particular case, there was no clinical evidence of extension outside the corpus. As long as the surgery was not performed because of disease progression, use information from the surgery to code EOD extension.

History:

For cases prior to 1998: Code the EOD-Extension field to 22 [Myometrium, inner half], under "Sounding of uterine cavity equal to or less than 8 cm in length."
