Question:

CS Extension--Brain and CNS: How is this field coded for a malignant brain tumor that presents as a lesion with significant pressure on the left frontal ventricle and dilation of the right ventricles? See Discussion.

Discussion:

CS Extension code 30 includes tumor that invades or encroaches upon the ventricular system. Does significant pressure mean the same thing as encroach?

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.Do not assign extension code 30 in this case unless there is evidence elsewhere of ventricular system involvement.

"Significant pressure" is not synonymous with encroachment or involvement. See the list of ambiguous terms for CS staging on page 121 of the 2007 SEER manual.
