Question:

EOD-Extension--Cervix: How do you code tumor extension described as "the in situ lesion extends from the cervix to the mucosa of the vagina"? See discussion.

Discussion:

Example: Cone biopsy of cervix and vaginal vault both show ca in situ. The op report stated: "lesion extending from the left lateral portion of the cervix onto the left lateral portion of the vagina." The pathologist stated it "appeared to be an in situ lesion extending from the cervix to the mucosa of the vagina."

Answer:

For cases diagnosed 1998-2003:

Code the Primary Site to C53.9 [Cervix uteri] and the EOD-Extension filed to 00 [in situ]. In situ is a measurement of invasion. Extension of the cervical in situ carcinoma via the mucosa to the vagina does not affect the EOD extension code.
