What is it?

Adult Waiver participants are eligible for additional occupational, physical and speech therapy services of a habilitative - not a restorative - nature.  These services require prior approval.  Each of the therapies must be recommended, in writing, by the individual service planning team.  The team must document the individual's specific therapy needs and services to be provided by a licensed professional.  These therapies should be long-term, working with the individual, family members, support workers and others, not short-term, acute restorative needs.

How Do I Become A Provider?

1.  You must have a National Provider Identifier (NPI).

Please see the National Plan and Provider Enumeration website for information on applying for a NPI.

2.  You must enroll in the IMPACT provider enrollment system as a Medicaid waiver provider. 

Please see the DHS DDD IMPACT information page for more information about enrolling in IMPACT as a DD waiver provider.  Providers

will enroll in IMPACT as Rendering/Servicing providers. 

After submitting an IMPACT application, please email Provider Enrollment the IMPACT application ID to ensure that the application is reviewed by a DDD Provider Enrollment specialist.

3.  You must complete a Payee Designation/Authorization Form (IL462-1180).

This form does not need to be submitted to DHS/DDD.  The form should be maintained in the records of the agency that is submitting the

billing for the therapy services.
