Insurance claim odyssey… who’s will pay??

I’ve been on a bit of an epic healthcare journey for the past 6 months. I took a blow to the shoulder at work and started a workers comp claim with them and went to their network urgent care for eval and x rays. I ended up having 3 total appointments at the workmed clinic and they told cleared me to return to work but but said they would refer me to pt. Weeks passed and they never connected me to a pt so I went ahead and started seeing one with my own insurance (bcbs) cause I was sick of waiting. Well, turns out they never referred me to pt cause my HR dept wasn’t properly relaying my claims info between the clinic and their workers comp insurance. I learned this when I ended up receiving the full bill for all the workmed appts, which luckily I was able to get all sorted out.

Months of pt later and no progress so I went to an ortho looking for an mri. He ordered it, but BCBS denied it due to lack of proof that I completed treatment first. My ortho did a peer to peer and I ended up getting the mri and was quickly recommended surgery which I got.

I recently got a subrogation form from BCBS asking if this is work related and for my workers comp claim number and stuff (which I gave them). My question is how will this saga end? Will BCBS go after workers comp? Will they both refuse and stick me with the bill? Do I need to talk to a lawyer?
