Question:
2018 EOD Primary Tumor/2018 EOD Mets--Lung: Is EOD Primary Tumor coded to 500 and EOD Mets 10 when there are bilateral lung nodules with nodules in same lobe as the primary tumor? How is EOD Primary Tumor coded when separate tumor nodes are in an ipsilateral lung but there is no documentation as to whether it is in the same or different ipsilateral lobe from the primary tumor?
Discussion:
Answer:
Assign 999 to EOD Primary Tumor if this is the only information you have for your case.The mention of nodules does not automatically mean that you have separate tumor nodules. There are many reasons for the appearance of nodules in the lung, some of which are not due to cancer. Unless you have further information on whether the physician has determined that they are related to the lung cancer, then assume that they are not related.
Assign 00 to EOD Mets. Do not code EOD Mets to 10 since you cannot determine whether those nodules are based on the tumor or not.
If you are able to obtain more information, then you can update the EOD Primary Tumor and EOD Mets.
Regarding the second question, if separate tumor nodules are noted, you cannot assume that they are due to tumor. Further information, or clarification, is needed on whether the separate tumor nodules are related to the lung cancer. Without further information, code EOD Primary Tumor to 999.
There is also some information in the CAnswer Forum since Separate Tumor Nodules are a Site-Specific Data Item: http://cancerbulletin.facs.org/forums/forum/site-specific-data-items-grade-2018/96061-lung-separate-tumor-nodules
