Revised Breast EOD Codes. June 25, 2002
Question:
EOD-Extension--Breast: The SEER coding scheme classifies the in situ portion as less than 25% [code 14] or equal to or greater than 25% [code 15]. How do you code a pathologist's statement of "less than or equal to 25%"? See discussion.
Discussion:
"insitu ca constitutes less than or equal to 25% of the total mass."
Answer:
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 14 [invasive and in situ components present, size of entire tumor coded in Tumor Size AND in situ described as minimal (less than 25%)]. The pathologist did not use a code as defined by SEER. For cases described as "less than or equal to 25%", choose the lower of the two EOD code choices.
