First, find a better doctor, preferably an endocrinologist who is familiar with adult onset type 1 diabetes. Ask that doctor to evaluate you thoroughly for the type of diabetes you have.
And don't panic, most insurance companies allow for type 2 diabetics if the clinical data is there. Any doctor worth your time will make sure they have the clinical data to back the decision up. A good place to start is with a fasting glucose and c-peptide. These will help determine if and how much insulin your body produces.
The last thing is - don't panic. Even if an insurance company denies you, you have the right to appeal their decision. Don't hesitate to appeal and or utilize business complaint reporting agencies such as the Better Business Bureau. I used them when my insurance turned me down for a surgery I badly needed, saying it was experimental. Never mind that the surgery has been in existence for over 60 years. I filed a complaint with better business and suddenly had an advocate at the insurance company instead of having to deal with their "support" line. Worked out really well.
Find a new doc and don't transfer reports.
Yes. You must go to an endocrinologist. I found many general practitioners do not know much about Diabetes. I was lucky that my primary care physician was honorable enough to recommend the best endocrinologist for Diabetes in New Jersey. I was diagnosed with Type 1 diabetes when I was 57 due to pancreatitis and Medicare approves every pump except the OmniPod because they say it's a luxury. I'm in the process of purchasing a different pump... Tandem. I'm not thrilled about it but I have no choice. Good Luck.
Misdiagnosis is widespread and unconscionable. I have inveighed against it at length elsewhere so I won't repeat it here. The traditional belief that "only children get T1 and only adults get T2" is very deeply entrenched, but this is the second decade of the 21st century and we know better. That sort of ignorance (or stubbornness) skates very close to the malpractice line, IMHOP. No excuse is acceptable.
You must get a correct diagnosis and your chances of that are enormously greater with an endo. And yes, it can have insurance implications. Serious ones. Just to pluck one example out of the air, it's very, very hard to convince most insurance companies to cover a CGM for a T2. It's possible but insanely difficult. The diagnosis really matters.
Exactly David and I just signed a petition for Medicare to approve the CGM along with many people on my Facebook page. They label it a "luxury"... hmmmmm a luxury that saves lives. Doesn't quite make any sense.
Sorry you're having to deal with this. The medical system has enough hoops they make you jump through without having to pile on this kind of nonsense. Good luck navigating the minefield! We're pulling for you. :)
Dear Lord!! 1) You need to dump this doctor,
and 2) You need to report him.....regardless of the fact that he is semi retired, this amounts to malpractice!
