回複：請較老貓大人和各位專家:保險公司拒付帳單, facility 要把我送到討債公司, 我該如何對付?

I think you should sue your insurace company if you have had pre-auth # and confirmed WRA in its network.
WRA did the service and of course they will charge someone.

Write a letter to your insurance company, and tell them why you felt it was their responsibility and your protential leagal action. you call also contact the state insurace department for your complait.

it is really the deal between WRA and Cigna.
