I am not sure about Oklahoma's WC laws.... Sounds like they are just stalling. Especially since you have been reimbursed before. Also, I would ask your lawyer if he could bring it up in your court date... maybe its not the time for that concern though It makes sense to me, but who knows!?
Another thing is you may want to address your question to this great forum for WC questions divided into threads by state http://www.workerscompensationinsura...play.php?f=685
I use this a lot and get quick responses from people Best of Luck!!!
