Yes thats true, one of the women at the front desk said next time don't tell the doctor anything you don't want them to write down in your medical records because they will, a scope was never done on me or anything to diagnos GERD, these doctors are out to make more money, the more they write in the chart the more money they make, I know I used to do medical billing. I now have to go on my husbands insurance and pay 400 dollars a month and thats just for medical, but you gotta have insurance if not doctors treat you terrible and sometimes won't even treat you at all. I do agree you can't listen to some of these opinions on here.
If a staff member is advising that you lie about your medical hstory or symptoms, they should be fired...immediately. That "advice" is dangerous and irresponsible.
In order to code appropriately to "make more money", the Physician must have thorough documentation of his/her observations, your complaints, their diagnosis, and plan for more than one body system. Insurance companes periodically review random charts for accuracy and to make certain that the Physician is practicing within the standard of care and billing appropriately. If you have recent experienced in medical billing, you'd already know that.
OP's usually get upset when the correct information is not the information they want to hear.
Edit to add: As ecmst stated earlier, an actual diagnosis does not have to be made. If there is documentation that the patient has taken an OTC med to treat indigestion/heartburn, the insurance company's reviewer will pick that up in the office notes and possibly designate it as "pre-existing".
