I recommend reading table 3 in this paper:

https://pmc.ncbi.nlm.nih.gov/articles/PMC7284300/

"It was stated in notes that I had lung cancer. I do not and never have had lung cancer."

"I did receive a referral for physical therapy, it was for the wrong body part"

"Doctor reported that I did not claim to have pain in my hand. I am a pianist and I went specifically because pain was in my hand."

"I have been complaining of difficulty breathing [for over 3 mo]... notes saying my breathing is normal"

And plenty more
