Inquiry Details
References:
2018 EOD Manual
Question:
EOD 2018--Lung: How should EOD Primary Tumor be coded when imaging describes a large left upper lobe 9.1 cm mass that Also noted is no pleural effusion and normal chest wall. See Discussion.
Discussion:
It is unclear if code 300 is appropriate, since technically the fissure is comprised of pleura, involvement of the fissure appears to imply a tumor that is no longer localized.
An argument could be made for code 400, since the term traverses could be interpreted as crossing into adjacent lobe, however the lower lobe is not mentioned in this scan.
Answer:
Assign code 400 as the term "traverses" indicates involvement with extension to the major fissure and is no longer confined to the left lobe.
