My doctors refuse to provide further documentation for my RA

I had a TEAMS call to discuss alternative recommendations that my doctor originally had wrote down on the form, along with recommending remote or telework. The call wasfrom people that are just relaying information to the decision maker, and I asked if I could get further documentation for my RA, and both of my doctors refused to provide more than just filling out the RA form that was provided to me. Should I be concerned that without further documentation, my RA will be denied?
