Wiki Coding recurrent bilateral lung cancer?

[apmgreer]

I've gotten myself so confused, so I'm hoping you can help me.

My case: In 2006, patient has left upper lobe squamous cell carcinoma. Treated with lobectomy and chemo. In 2015, patient returns with bilateral lesions that physician decides is a recurrence. This time right upper lobe and left lower lobe squamous cell carcinoma.

Is that a primary neoplasm of C34.12 (the 2006 left upper lobe) with two secondaries of C78.01 and C78.02? Or a history of lung cancer (Z85.118) with C78.01 and C78.02. Or am I totally off the mark?

Thanks in advance!

Recurrence

I do not think it is an exact recurrence because the sites are not the same. You should read the path report. That will tell you if this is metastatic or a new primary.
