Disgustingly common, and techs do it too!. I was scanned and the tech wrote that he could see both of my ovaries and my appendix clearly. I had one ovary damaged by an earlier surgery and my appendix was removed when I was 9 years old! To them, it is just hitting buttons and filling in data they forgot to take note of, but to patients it could be the denial of a much- needed test or of insurance coverage.
Also, when I was asked to painstakingly fill out thick survey of medical conditions within my family and extended family, whomever entered the data must have gotten lazy because they left half of the repot out and they misattributed what they DID entered to incorrect family members ( which definitely could exclude me from coverage or testing!). When I brought it up with my doctor he shrugged it off and made a joke about it! Even when I pressed, they refused to correct their “official document”. So, I wrote an “official” medical message, that is supposed to stay part of my official record, and stated all of the errors and detailed the lack of concern.
If this is how it is now, I am sickened to think where high risk patients and the retired will be for care a generation or two from now.
