Much depenRAB on what disabling conditions you have, if you've already been approved for STD and are now transitioning to LTD, your occupation, what type of doctors you are seeing, and your condition history.
I went out of work in May 09. I already had a history of 2 recent (06 and 08) neck surgeries and prior back surgery in 1993. I went out for back and neck pain I had a 2 year history of active treatment with a Pain Management doctor. My job at the time was part sedentary and part more active (customer visits in the surrounding states (TX, NM, NV).
Add this all up and my STD was approved right away 6 month later when LTD came around I was approved as I had undergone PT and testing and was moving toward surgery. I had surgery in 02/2010 and now LTD is asking that I apply for SSDI. That's a signal that LTD expects the claim to last longer.
Having an IME early is rare. The first claim review is a comparison of all medical information in comparison to the requirements of your occupation. Most LTD companies give you Attending Physician Statement (APS) Forms for you to give to doctors. Give them to any and all treating providers. But first craft your own "Personal Statement of Disability" that you give as a tool to each doctor. Follow the APS form and craft your statement "My job requires the following which make me unable to do these tasks due to my symptoms/conditions of X, Y, Z and then follow the APS answering from your perspective.
Is the LTD through your employer? If you are open to it share with me your job and current conditions and I may be able to give you some tips. Besides being a spine and knee disaster I spent 15 years in STD and LTD industry from Claims to Account Management. In my case my LTD began at 6 month out of work but plans vary.
