I am filing bancruptcy for high medical bills and my lawyer needs a list of creditors from when I had first started going into debt. I don’t remember all the hospitals and doctors and some of the ones I do remember are not on the credit reports. How do I find them from that long ago?
There was no insurance at the time to cross reference and the medical records were altered over the course of the past decade. No cross reference there either.

Look at forms relating to health insurance.
Look at your medical records.
