Can't go back to Work?

Although my doctor said I can go back to work on the 17th, my Ins. carrier said no I can't. WTF??

I called my Ins. carrier person who is looking after my file to let her know I got the OK from the Doctor to go back to work. She quickly said, no I can't, not until I get assessed by there rehab specialist from the Ins. company.

She wanted me to Fax her my note from the doctor, (which i did today) to her first, before she can do any processing. She then asked me a bunch of questions about my doctors visit, what he said etc. She told me once she receives the Faxed note she will start the process, but she won't be able to get to it until the end of march break.

She told me when she gets the Fax, she will make an appointment with the rehab specialist to meet with me and evaluate me, which will take a few weeks to book. Then after I get evaluated with rehab specialist, they have to do a report to decide if I'm ready to go back to my job at work. Then the rehab specialist has to set up a meeting with my employer to let them know my progress? which could be another week? and if acceptable to the rehab specialist and my employer that I meet all the criteria and can do my job? then I can go back to work.

So I won't be going back to work for a while yet?
