I'm a new pathology coder without internal resources to consult and I'd appreciate if anyone could help me out with this - I am getting several clinical histories of "metastatic lung adenocarcinoma" and "metastatic squamous carcinoma", and very limited supporting paperwork. Am I to assume that the cancer to which they are referring should be coded as secondary or primary? For example, in the first scenario, would I use 162.9 for primary malignant neoplasm of lung, assuming it has metastisized to another location or 197.0 for secondary malignant neoplasm of lung, assuming that it is a cancer that has metastisized to the lung?
Thanks for any help!
