Aetna thought my orthopedia surgeon's restrictions weren't good enough

I have a short term dissability claim with Aetna. Every time I have a doctors apointment they demand paperwork that day. They are constantly closing my claim. When you talk to them it’s a different person every time. An orthopedic surgeon sent them limitations on my torn tricep and they say I don’t have a disability. Now my company will not take me back and suspended my medical benefits because of Aetna but my employer wil not take me back untill I have clearance from my doctor. I guess they have surgeons looking at paperwork? When asked if he recieved the 15lbs restriction he said yes. That’s from an orthopedic surgeon I said. He said that’s not enough. I had my doctor, and a physical OD send him paperwork. He said I would have to file an appeal.
