Steps
Compare the provider bill with the EOB in the member account.

If a claim was processed wrongly, file an appeal at the address on the EOB or denial letter.

Protects patients from out-of-network surprise bills for emergency care, for non-emergency care by out-of-network providers at in-network hospitals and surgery centers, and for air ambulance services.
