Join Our Network

BCBSIL welcomes the participation of new providers in our networks. We contract with physicians, facilities and other health care professionals to form provider networks essential for the delivery of quality, accessible and affordable health care services to our members.


STEP 1 – Select your network.
Before requesting an application for participation in the BCBSIL network, review the product requirements in the Contracting section.

STEP 2 – Request an application.
After reviewing the eligibility requirements and reimbursement guidelines, you can request an application for participation in the Participating Provider Option (PPO) or Blue Choice PPOSM networks.

Once you submit your application, you will receive a contract to complete, sign and return to us.

Providers who wish to join the HMO network must first be contracted with one of our participating HMO Medical Groups or IPAs.

STEP 3 – Become credentialed.
All providers seeking participation in the BCBSIL HMO, PPO and Blue Choice PPO networks are required to complete a credentialing process prior to acceptance.

Our credentialing requirements are derived from and in compliance with the State of Illinois and National Committee for Quality Assurance (NCQA) Credentialing standards.

STEP 4 – Get connected.
BCBSIL contracts include provisions related to some electronic data interchange (EDI) transactions to help ensure timeliness, accuracy and security of claims-related information.

Participation is strongly encouraged in all electronic options available to BCBSIL providers, including: 

  • Electronic Funds Transfer (EFT)
  • Electronic Remittance Advice (ERA)
  • Electronic Payment Summary (EPS)
