Orthopedic surgeon recommended surgery on both knees, after MRI results and ex rays. Other workers comp doctor agreed. What do I need to get surgery approved. The consulting doctor states on his report that the diagnosis for surgery is only good for 45 days. What does this mean? I am still trying to work with restrictions, but am really struggling. I am working with restrictions, but do not feel I can continue. I am 61 yrs old. Have always worked and never had a claim. How do I get approved to stay home till my surgeries and healing are over?
