I would think they need to do pathology on the lobe removed. I don’t think they wouldn’t do it if a patient had the other lobe originally removed due to cancer. I also think they wouldn’t need to justify removal of the 2nd lobe to the insurance company based upon noting suspicious nodules/calcifications, etc. and needing to be on thyroid medication for life.

My sister had thyroid cancer at 27 and first had her one lobe removed and when pathology confirmed cancer, she had the 2nd lobe removed. I had a suspicion 2.5 cm nodules in my right lobe (I was in my early 50s) that was removed and it was not cancer but pathology found a micro cancer. I still have my left lobe but there is a large macro calcification and I am taking levothyroxine for hypothyroidism now. At some point, I might need the left lobe removed. If I was able to elect to have it removed, I would hope they would do the pathology on the macro calcification.
