I was hospitalized in 2016 and my tests were sent here for reading. At the time I was on my father's insurance as I was under 26. In December 2020 I was hospitalized and my tests were sent here for reading. While they could bother to reach out to the hospital to verify that I had a new address, they went ahead and tried to bill an insurance that was over 4 1/2 years old. I am no longer on that insurance.

Because of this issue, my father's insurance has sent him an EOB with details about the procedure and tests I had done. This was not knowledge I wished to share with my father, as I am a grown adult with my own life and insurance (which I gave them on the phone ages ago to clear up the bill, not knowing they had already tried to bill an outdated insurance plan).

This is a massive violation of privacy. The hospital that the tests were done at had my information and they clearly reached out for an address to send a bill to. I even have a different last name since using them in 2016. So why could they not have spent two minutes double checking the information on file before billing?
