Support all Tennesseans with intellectual and developmental disabilities to live fulfilling and rewarding lives.
To become the nation’s most person-centered and cost effective state support system for people with intellectual and developmental disabilities.
The Department of Intellectual and Developmental Disabilities (DIDD) is the state agency responsible for administering services and support to Tennesseans with intellectual and developmental disabilities. This is done in several ways, including Medicaid waiver Home and Community Based Services (HCBS), state-operated ICF/IIDs, and the Family Support Program. DIDD administers services directly or through contracts with community providers. DIDD strives to partner with the people it supports and their family members and friends.
HCBS Waiver Services
DIDD services are primarily offered through three HCBS waivers. These programs were developed as an alternative to services provided in an institutional setting:
Comprehensive Aggregate Capped (CAC) Waiver: This waiver includes former Arlington Class members, Clover Bottom class members and persons whose services exceeded the Statewide Waiver Annual individual expense cap prior to its implementation on 3/27/15.
Statewide Waiver: The Statewide waiver offers a variety of services for persons with intellectual disabilities, including day, employment, residential, personal assistance, behavior services, and support coordination among others. Service needs must be met within an annual individual expense cap, set at the current average cost of private ICF/IID services.
Self-Determination(SD) Waiver: The Self-Determination Waiver offers services to persons with intellectual disabilities who have moderate service needs that can be satisfactorily met with a cost-effective array of home and community services that complement other supports available in their homes an community. This includes case management, day services, behavior services, respite, personal assistance and transportation.
Employment and Community First CHOICES: A new program for people with intellectual and developmental disabilities. This program is operated by TennCare through its managed care organizations. Services in the new program will help people become employed and live as independently as possible in the community.
