Easier said than done. I've been fighting to convince hospital I didn't have a knee replacement while there. They keep saying “I says on the computer you did.” I Ask them why I don't have any scar on my knee, a question they never answered. I have talked to medical records, my doctor, the hospital radiologist, the hospitalist and the doctor of the ladies medical records that got mixed up with mine.
Another hospital claims I have a depression problem. The problem seems to be that no one is willing to admit, they made a mistake. If it's on a computer it seems to be gospel.
Good luck with getting your records changed.
I hope the people you deal with are more reasonable than the ones I dealt with.
