getting a second opinion is not fraud. but by the time you're getting the tenth opinion just because the first nine docs didn't give you written justification to draw on public funds, that looks pretty fraudulent.
or put a different way, GP is describing people explicitly admitting that they went to as many doctors as it took to get specific language in a note. they admitted that they didn't care at all about any therapeutic outcomes from all those visits. assuming this isn't a tall tale, does that sound like a good faith use of the system to you?
