Early Interventon Provider Payment Update Effective 05/23/17:

Early Intervention has secured funds to process the Provider Voucher for the week dated 03/08/17.  This voucher was approved today and will post on the Comptroller’s website within the next few business days. 

Please continue to watch the Comptroller’s website for further payment information.   

Early Intervention is continually working to secure additional revenues in order to process additional payments.  We are not always aware of when these funds may be released to the Early Intervention 502 Revolving Fund.  We also must have the funds secured into the DHS accounting systems before payments can be made.  The balance on the IOC may vary from the DHS accounting system due to pending obligations.  IOC is only the first step in the process.  While we understand the impact any delay has on every aspect of the Early Intervention Services System, we are not able to change the way the state process works.  Early Intervention receives funding from multiple sources and every effort is made to reduce the impact of the lack of funds available from one source by utilizing every other source possible.  As funds become available, payments will be made.

As always, thank you for your continued support and patience.
