From what I know of it and if claim is accepted - comp should pay for all related costs for treatment & care , as well as missed wages (or % of wages).

Drs office visits ( no co pays needed)
PT if needed
ER/Hospital costs
medications

keep track of mileage to appts and care providers that is reimbursed too. or taxi /bus etc. unless it has changed.

My Oregon claim (yrs ago) all those were paid - until denied - then got comp atty for appeal & hearing- but he wrote a letter to all treatment providers to put billing on hold til hearing /case was done. Then the bills were sorted out at end.
My atty was not the best, I should have interviewed more attys, and asked more questions. his office was not very organized - that should have gave e a clue early on...
I only had dial up Internet back then so that was part of the problem..for searching and checking attys..soo slow..
