Question:

EOD-Extension--Head & Neck (Tonsil): How should the EOD-Extension field be coded for bilateral tonsil involvement? See discussion.

Discussion:

Tonsillectomy and bilateral radical neck dissections were done. The path diagnosis was left and right tonsils: squamous cell carcinoma, bilateral tonsils with negative inked surgical margins of resection. Physical exam and operative findings did not mention any extension beyond the tonsils.

We originally coded the EOD-Extension field to 30 for a bilateral tonsil primary. The case failed the SEER Edit IF41 (Primary Site/Lat/EOD). According to that edit, if laterality is 4 then the EOD-Extension field must not be 00 through 30.

We recoded the EOD-Extension field to 99 in order to comply with the SEER edit.

Answer:

For cases diagnosed 1998-2003:

Code EOD extension as 30 [Localized, NOS] and laterality as 4 [Bilateral involvement]. The next update to the SEER edits will allow this combination.
