Tennessee Department of Disability and Aging

What the Department of Disability and Aging Is

On July 1, 2024, Tennessee merged the former Department of Intellectual and Developmental Disabilities (DIDD) with the Commission on Aging and Disability to create the Department of Disability and Aging, or DDA. If you've been navigating Tennessee's disability system for years and suddenly can't find DIDD online, this is why — the agency still exists, but under a new name and a broader mandate.

DDA is the state agency responsible for coordinating services for Tennesseans with intellectual and developmental disabilities (I/DD) and older adults. It partners with TennCare and contracted Managed Care Organizations (MCOs) to administer the state's primary Medicaid waiver program for people with I/DD — Employment and Community First CHOICES — and operates three regional offices covering West, Middle, and East Tennessee.

What DDA Actually Does for Families

DDA's core function for disability families is managing access to ECF CHOICES, Tennessee's Medicaid home- and community-based services program. ECF CHOICES funds the supports that keep people with intellectual and developmental disabilities living in their communities rather than in institutions: personal assistance, employment support, community integration, assistive technology, and respite care.

DDA also handles:

• Clinical eligibility determinations for I/DD waiver services
• Referral list management for ECF CHOICES enrollment (the waiver has capped enrollment, so eligible people who can't enroll immediately go on a statewide referral list)
• Crisis intervention for situations like caregiver loss, homelessness, or severe behavioral emergencies — DDA can prioritize reserve-capacity slots for urgent cases
• Provider oversight for residential and day program providers serving people with I/DD
• Coordination around abuse and neglect protections, including the Tennessee Department of Health's Vulnerable Persons Abuse Registry

How ECF CHOICES Groups Work

ECF CHOICES isn't a single program — it's organized into benefit groups that match the level of support a person needs:

Group 4 — Essential Family Supports. Designed for individuals living at home with family. Annual expenditure cap of $18,000 (excluding minor home modifications). The standout feature is the Family Caregiver Stipend: up to $500/month for members under 18, and up to $1,000/month for members 18 and older, paid directly to a family caregiver instead of hiring agency-based home care workers. The caregiver doesn't need to register through the fiscal agent system — it's a flat stipend.

Group 5 — Community Living Supports. For adults 21 and older focused on employment. Annual cap of $36,000 (up to $42,000 with emergency authorization). Emphasizes integrated competitive employment and independent living skills.

Group 6 — Comprehensive Supports. For adults 21 and older requiring substantial daily assistance. Tiered caps of $54,000, $82,000, or $108,000 depending on need level, with exceptional authorizations up to $301,000 for the most complex cases.

Groups 7 and 8 — Severe Behavioral Supports. For children (Group 7) and adults (Group 8) with I/DD and severe behavioral support needs. Year one caps for Group 8 run to $513,625.

Who Qualifies

Two clinical requirements gate access to ECF CHOICES:

1. Intellectual disability diagnosed before age 18, OR developmental disability diagnosed before age 22
2. The individual must meet a nursing facility level of care (or be at risk of institutionalization)

Financial eligibility follows Medicaid rules: countable assets can't exceed $2,000 for the individual, and gross monthly income is capped at $2,982 (300% of the 2026 SSI Federal Benefit Rate). If income exceeds the cap, the person must establish a Qualified Income Trust — Tennessee's version of a Miller Trust — to hold the excess and maintain eligibility.

A critical detail for families approaching the 18th birthday: once a child turns 18, parent income and resources are no longer counted toward the child's eligibility. Many families who were previously over-income suddenly qualify based on the young adult's own limited income alone — often just their SSI check.

How to Access DDA Services

Self-referrals are accepted. The process starts by contacting the DDA regional office for the area where the person lives:

• West Tennessee (Memphis metro and surrounding counties)
• Middle Tennessee (Nashville metro and surrounding counties)
• East Tennessee (Knoxville, Chattanooga, and surrounding counties)

The regional office will walk you through the referral process, coordinate clinical assessments to document that the disability originated before the statutory age limits, and place the individual on the ECF CHOICES referral list if they're clinically and financially eligible.

Timing matters. The referral list is subject to prioritization for urgent situations, and ECF CHOICES enrollment is capped by annual state budget appropriations. Beginning in July 2025, TennCare and DDA started releasing 2,500 new slots in monthly increments of 100 to clear the existing referral list — but demand consistently exceeds supply.

Where DDA Fits in the Transition Timeline

For families of a young adult with I/DD approaching 18, DDA is one of several agencies you'll need to coordinate with simultaneously:

• School system — IEP transition planning, transfer of educational rights, diploma pathway decisions
• Social Security Administration — SSI age-18 redetermination, Representative Payee designation
• DDA — ECF CHOICES referral, clinical eligibility assessment
• Department of Human Services, Division of Rehabilitation Services — Vocational Rehabilitation and Pre-Employment Transition Services

These agencies don't coordinate with each other automatically. You're the hub connecting them all, and each has its own deadlines, paperwork, and eligibility rules.

The Tennessee Adult Guardianship & Alternatives Guide organizes the entire timeline into a sequential calendar — covering what to do at age 17, on the 18th birthday, and in the months following — so you're not juggling four agency workflows from memory. It includes the DDA referral checklist alongside the legal authority decisions (power of attorney, supported decision-making, or conservatorship) that determine who signs the care plans once services are approved.
