SEER EOD-88,3rd Ed, 90
EOD-Extension--Lung: If a CT scan indicates that a patient has evidence of "long-standing pneumonia," is that synonymous with "pneumonitis" for the purposes of coding extension for lung primaries?
No. These terms are not synonymous. For cases diagnosed 1998-2003, disregard the pneumonia and use the other available information to code extension.
