Inquiry Details
References:
SEER EOD-88,3rd Ed, 2, 146. January 1998
Question:
Ambiguous terminology/EOD-Extension: Is the term "within" a term of involvement in coding extent of disease? See Description.
Discussion:
For example: a kidney tumor is described as "completely encased within the renal capsule with no extension into perirenal fat." Does this mean the renal capsule has been invaded (extension code 20) or that the tumor is totally contained within an area surrounded by the renal capsule (extension code 10)?
Answer:
For cases diagnosed 1998-2003: The term "within" is not one of the listed ambiguous terms for EOD. Determine extent of involvement from the context in which "within" appears.
In the example, "Encased" is an ambiguous term meaning not involved. Code extension for the example to 10 [Invasive cancer confined to kidney cortex and/or medulla].
