Compass is in-network with BCBS PPO and HMO Illinois, Humana, Cigna, Compsych, Aetna PPO and University of Chicago Insurance Companies. Our Utilization Review Department will work with all insurance companies, whether in or out of network, to pre-authorize and prove medical necessity. If we are out of network with your insurance company, Compass will submit claims to most insurance companies, so that you can be reimbursed your out of network benefits.
