Overview of the EI-CBO Billing Process
Providers are expected to bill the EI-CBO at their usual billing rates with the understanding that the EI-CBO will always reimburse up to the established Early Intervention rates. Providers should refer to the document entitled "Early Intervention
Service Descriptions, Billing Codes and Rates" for detailed information on staff qualified to provide EI services, billable activities and rates of reimbursement. Providers who accept an Early Intervention authorization agree NOT to bill a child's family
for payment above the Early Intervention rates.
Who can Bill?
Services are to be provided by a credentialed and enrolled provider. If services are provided by a credentialed associate level EI provider they must work under the supervision of a professional level EI credentialed provider who has a pre-approved
authorization for the services to be provided.
The EI-CBO can reimburse an agency for Early Intervention services that are provided by an equally qualified provider who is Early Intervention credentialed/enrolled with the EI-CBO under the same discipline and is employed by the same agency the
authorization was issued to. This policy ONLY permits substitution of those providers who are enrolled under the same agency's tax payer identification number.
Private Insurance Use
When a child enrolled in Early Intervention is covered by a private insurance plan, all credentialed providers must bill the insurance before submitting claims to the EI-CBO unless an exemption or waiver has been approved for the child.

Time to Bill
Claims for authorized services rendered on or after service dates of July 1, 2005 must be submitted to the EI-CBO no later than ninety (90) days following service delivery. In cases where third party payments exceed the Early Intervention rate, the
provider's bill will be considered paid in full. The provider must submit the claim along with the insurance EOB showing the charges were paid in full. Charges that do not exceed third party recoveries should be submitted to the EI-CBO and will be paid
up to the level of the Early Intervention rate. A copy of the insurance carrier's explanation of benefits must accompany the provider's billing to the EI-CBO.
Remittance from the EI-CBO
Attachment G: Sample Provider claim summary will explain the action taken on each claim and will be mailed from the EI-CBO. Claims approved for payment will be forwarded to the Illinois State Comptroller's Office for
issuance of a check/warrant (Attachment H: Sample Comptroller Check). Providers can directly access payment information through the State Comptroller's web site. An
online vendor's guide to accessing payment information is also available at the web site.
The Provider Claim Summary (PCS) and the check/warrant are sent under separate cover and can be matched according to the invoice number shown on the Provider Claim Summary and the invoice number on the state check/warrant. If you have questions
regarding information contained within the Provider Claim Summary, contact the EI-CBO Call Center at (800) 634-8540. Please do not call the phone number listed on the State Comptroller's check/warrant.
The family will also receive an Explanation of Benefits. Families are requested to review their Explanation of Benefits (EOB) and report dates of service that were paid, but not received. Families who identify a discrepancy between services paid and
services provided should contact the EI-CBO Call Center at (800) 634-8540 to report the discrepancy.
