Understanding Long Waitlists and What to Do While You Wait
The HCBS waiver waitlist is rationing dressed in administrative language. The wait is real, the wait is long, and the wait is also productive territory if the family uses it deliberately. Four tactics that compound over the years on the list.

Put the autistic adult on every available list tonight.
State HCBS waivers. State Medicaid. State developmental disabilities council interest lists. Local Centers for Independent Living. Local Arc affiliates. Each is a different door. Each accumulates time independently. The application is mostly the same packet, photocopied. The first hour of applications is worth the first three years of waiting.
The list is rationing
Federal law lets states cap waiver slots. KFF surveys consistently document hundreds of thousands of people on HCBS waiver waitlists nationally, with wait times measured in years for many states. The cap is policy, not nature.
Apply to every list
Most states operate more than one waiver. Most have multiple Medicaid pathways. The Arc maintains an interest list. The CIL maintains an interest list. Apply to all of them.
Risk documentation
States that prioritize by risk move people up when need increases. A documented health incident, caregiver hospitalization, or behavioral escalation moves the file. Keep the log current.
Typical wait
Median IDD waiver waits run several years in most states, with some over a decade. Some states under one year. The variance is policy, not population.
Interim supports exist
State plan Medicaid covers some services without the waiver. Vocational rehab funds work-related services. School transition services run until 22. ABA insurance benefits cover therapy. None of these require the waiver.
Build the routine now
The day program, social schedule, transportation rhythm, and DSP rotation that the waiver will eventually fund can mostly be assembled in advance with family, community, and small private spend. Build it. The waiver fills in.
Where to apply and what to track
We put our daughter on every list we could find when she was twelve. By the time she was twenty-two, we had been waiting for ten years. Her name came up two months after my husband’s first heart attack. The case manager said the heart-attack documentation, filed the week it happened, was what moved the file. We had been keeping the log for years because somebody at the Arc told us to. We did not know it would matter until it did.
Working the list
- Apply to every state waiver, state Medicaid pathway, and adjacent interest list this month.
- Start the risk-documentation log. Caregiver age, health incidents, behavioral escalations, housing instability.
- File state-plan Medicaid service requests for what does not require the waiver.
- Enroll in Vocational Rehab, school transition, and any insurance-funded ABA available.
- Recheck waitlist status in writing every six months. Update risk documentation at each check.
- HCBS waiver applications submitted (every available)
- State Medicaid plan benefits enrolled
- Arc / CIL interest list confirmed
- Vocational Rehab open case
- Risk-documentation log started
- Interim service routine in place
- Six-month list re-check on calendar
The wait is policy, not destiny. The years on the list are billable hours toward the day the call comes.
The full story · For readers who want context
Linda put her daughter on every list the Arc of Marquette County had ever heard of when her daughter was twelve. They added more lists each year, as the family learned new ones existed. By the time her daughter was twenty-two and aging out of the school transition program, the family had been waiting ten years for an HCBS waiver slot. Linda’s husband had his first heart attack three months later. The next morning, while her husband was still in the cardiac unit, Linda filed an updated risk statement with the regional service entity. Two months later, the waiver slot opened. The case manager who called said the cardiac documentation, current to the week, was what moved the file. Linda had been keeping a risk log for years because a parent navigator at the Arc had told her to start one. She had not known it would matter until it did. That is how the system works for families that learn the rules. That is how the system fails families that do not.
The four tactics that compound.
Here is what they will not tell you on the front of the state Medicaid website. The HCBS waiver waitlist is rationing dressed in administrative language. Federal law lets states cap waiver slots; most states do; demand exceeds supply; some families wait. The wait is real, the wait is long, and the wait is also productive territory if the family uses it deliberately. Four tactics, applied in the first year on the list and maintained through every year that follows, do most of the work that determines whether the eventual call comes earlier or later, and whether the family is ready for it when it does.
Apply to every list. Document the risk. Request interim supports. Build the community-based routine now. Each tactic compounds. Time on each list accumulates. The risk documentation grows in evidentiary weight as it gets longer and more current. The interim services teach the family how the system actually works before the waiver lands. The community routine that family builds becomes the scaffolding the waiver eventually pays for. The four tactics together turn the wait from passive into preparatory.
Tactic one: apply to every list.
Most states operate more than one HCBS waiver. Some operate four or five. Each targets a slightly different population and has its own application, its own waitlist, and its own pace of slot openings. Apply to every waiver that an adult with autism plausibly qualifies for. The applications are mostly identical. Photocopy the packet. File each one. Each becomes a separate clock.
Beyond waivers, state plan Medicaid covers some services without waiver enrollment, including (in most states) basic behavioral health and some community-based supports. The state developmental disabilities council may maintain a separate interest list for state-funded services. The local Arc affiliate and Center for Independent Living often maintain their own service lists for sliding-scale and grant-funded programs. The state Vocational Rehabilitation agency opens cases for work-related services without any waiver. Each of these is a different door. None of them require the others. Apply to all of them.
The applications themselves take an afternoon. The cumulative effect is years of accumulated seniority across multiple programs, increasing the probability that one of them comes through before any of the others. A family that waits to apply until services are needed has already lost the years they could have been queuing. The first hour of applications is worth the first three years of waiting.
Tactic two: document the risk.
States that allocate waiver slots by something other than strict first-come-first-served use risk priority categories. The labels vary: “in crisis,” “urgent,” “planning,” “future need,” or similar. Movement between categories drives movement on the list. Documentation drives the categorization.
The Linda example is the prototype. A heart attack documented the week it happens, in writing, with hospital admit/discharge records, moves a file from “planning” or “future need” to “urgent” overnight in most states. The same heart attack reported informally over the phone, six months later, may move nothing. Documentation is the difference. Documentation also matters when the eventual person-centered plan is being written, because the same risk log informs the service authorization.
Tactic three: request interim supports.
The waiver is not the only service door, even though the waiver is the one most discussed. State plan Medicaid covers a meaningful set of services that do not require waiver enrollment: behavioral health services, some community-based mental health, basic case management, some early-intervention extensions. Insurance-funded Applied Behavior Analysis, available under most state autism insurance mandates and through Medicaid managed care, covers therapy hours that the waiver would otherwise have to fund. Vocational Rehabilitation funds employment services through state and federal Rehabilitation Act dollars without any waiver requirement. School transition services under IDEA Part B run through age 21 or 22 in most states. Local Centers for Independent Living offer peer mentoring and independent-living skills training at no or low cost.
Each of these is a partial bridge. None of them substitute for a full HCBS waiver service array. Combined, they reduce the gap between what the family currently has and what the waiver will eventually fund. Equally important, they teach the family how to navigate Medicaid case workers, how to read service plans, how to push back on inadequate authorizations, and how to maintain a documentation routine. By the time the waiver lands, the family is fluent in the system. That fluency is worth months of post-enrollment confusion.
Tactic four: build the routine now.
The autistic adult’s life on the waiver, when it eventually arrives, will include a weekly schedule, a community presence, a set of trusted helpers, and a rhythm of activities matched to the adult’s interests and needs. None of that is built by the waiver. The waiver pays for it. The family builds it.
Most of what waiver-funded supports do can be approximated, modestly, by family routines while waiting. Day-program substitutes: library volunteer hours, recurring community-center activities, sibling-led weekly outings, faith-community groups, hobby clubs. Direct Support Professional substitutes: an older sibling or cousin who agrees to one regular afternoon a week, a paid babysitter scaled up to adult care, a college student studying social work. Respite substitutes: a weekend visit with grandparents, a planned overnight at a sibling’s home, a small private respite budget pooled by friends. Transportation substitutes: family driving, paratransit (which most adults with disabilities qualify for outside the waiver), ride-share with disability-aware drivers in some markets.
None of this is glamorous. Some of it costs out of pocket. All of it is real, current, and accumulating into the routine that the waiver, once funded, will pay for at scale. The family that has been running a modest version of the routine for years walks into the person-centered plan meeting knowing what works, what does not, and what the adult actually wants. That clarity drives a better plan.
What other states make easier.
Several states publish current waitlist data on public dashboards (Tennessee, Pennsylvania, Indiana). Several states fund Parent Navigator and Family Resource Center positions specifically to help families work the list during the wait years (Massachusetts, Wisconsin). A handful of states have effectively eliminated waiting lists for IDD waivers by funding services through state general fund supplements (Arizona, Vermont, the District of Columbia). Most states fall somewhere in the middle, with multi-year waits, limited risk-category transparency, and modest navigator support. Michigan funds case management through Community Mental Health and the PIHPs, but with less public-facing waitlist data and less parent-navigator presence than some peer states. Other states made different choices about transparency. Michigan didn’t, as widely.
Your assignment this week.
Tonight: identify every waiver, Medicaid program, and adjacent interest list available in your state and file every application. This week: start the one-page risk log on the kitchen table. Within thirty days: enroll in every interim support the family qualifies for that does not require the waiver. Within sixty days: build the community-routine scaffolding, even if modest. Within six months: re-check the waitlist status in writing and file an updated risk statement. None of this guarantees a faster call. All of it changes what happens on the day the call comes. The wait is policy, not destiny. The years on the list are billable hours. Other states made the years easier. Michigan didn’t, fully. Now we know what we are fighting. Together.
