It a work comp claim/case so there are lots of rules to go by, it is very different from using pvt ins.
Have to get authorizations for other drs and that takes time.

If you are in a lot of pain, you should seek out a good work comp atty to help you get the best outcome. A good atty will help you get to drs of your choice and not just the comp ins drs.

You might explore our Workers comp forum for tips on claims and how that system works.
