Saw established orthopedic who is now Out of network

I saw an orthopedic doctor for back and neck pain and I saw him before not realizing I was on a different insurance carrier. He is now out of network and I paid out of pocket for today’s visit and X-rays but he referred me to get an MRI and Physical therapy (I will make sure they are both in network) My question is if i switch to an in network doctor, should i go through with MRI and physical therapy or hold off? OR should i stick with the out of network doctor.
