The Care Access Gap
What Happens When Mental Health Falls Outside What Medicaid Covers
On paper, Medicaid can cover mental health services, and for many families, this matters. But coverage and access are not the same thing, and the gap between the two is wider than most people realize. It's the same problem families run into elsewhere in this system - approved for services but can't find providers - just showing up in a different corner of it.
About one-third of private practice therapists and counselors accept no insurance at all. The number who accept Medicaid is smaller still - and has been shrinking. A 2024 study published in Health Affairs Scholar1 found that Medicaid reimbursement rates for psychotherapy average roughly 40% below what providers charge out of pocket, creating a built-in financial disincentive for providers to take on Medicaid patients at all. For families who can't afford private-pay rates, which averaged over $140 per session, the gap between coverage and care often means no care. People don't opt out because they don't want help. They opt out because the math doesn't work.
There are two separate situations worth naming here because they create different planning problems.
The first is familiar to many families of adults with intellectual and developmental disabilities (IDD): they have a Medicaid waiver, which covers a lot, but it doesn’t cover everything. This gap often includes mental health services. A waiver built around residential support and day programming wasn’t designed to pay for a psychiatrist who specializes in dual diagnoses.
The second situation is less discussed and harder. In most states, Medicaid waiver access for long-term disability services requires a diagnosis of intellectual or developmental disability. Mental health conditions alone - depression, anxiety, bipolar disorder, schizophrenia, even severe and persistent mental illness - won’t meet the requirements in most states. If your family member has significant mental health needs but no IDD diagnosis, the waiver door was never open to begin with. They’re navigating a system that wasn’t built for them, and the planning tools most families rely on weren’t designed with their situation in mind either.
Both groups end up in the same place, trying to fill a need without bankrupting themselves. Stuck because it’s not fully funded by Medicaid, providers are hard to find, and it’s unclear if any financial tools are available.
What the waiver does and doesn’t cover
For families with a waiver, the boundary between waiver-funded services and mental health coverage is worth understanding before a crisis makes it urgent. Medicaid waivers for IDD typically fund residential support, meaningful day/community living, personal care, and behavioral services. Behavioral support and mental health treatment overlap but aren’t the same thing - a behavioral support specialist working on adaptive skills and a psychiatrist managing a mood disorder are doing different work, funded differently.
Psychiatric care, therapy with a dual-diagnosis specialist, medication not covered by Medicaid’s formulary, and residential mental health treatment are expenses that may fall partially or entirely outside what waivers cover. The specifics depend on your state and your waiver type, which is why asking your waiver coordinator now - before you need the answer - is worth doing.
For families without a waiver, the picture is simpler and starker. Standard Medicaid covers mental health services in every state, but the provider network for adults with disabilities is thin, and intensive services can hit coverage limits quickly. Even when Medicaid does cover a psychiatric medication, the path from prescription to medicine in hand isn't always direct2.
Prior authorization requires a prescriber to obtain approval from the state Medicaid agency before a drug can be dispensed. Step therapy requires trying a lower-cost medication first - even if the prescribing physician believes it's the wrong choice for that patient - before Medicaid will approve the one they actually want to prescribe. Both tools are used in every state Medicaid program, and psychiatric medications are a common target. When standard coverage runs out, or when the only provider who gets it doesn't take Medicaid, the cost lands on the family.
What the Special Needs Trust can cover
The Special Needs Trusts (SNTs) I've seen over the years were written to allow distributions for medical and therapeutic expenses, which can include mental health care. Psychiatric care, therapy, medication not covered by Medicaid, and residential mental health treatment are distributions most trustees would approve - but "most" isn't "all."
If you have an individual trust, ask your attorney to confirm mental health expenses are explicitly covered, not just assumed. If you're joining a pooled trust, ask the same question before you sign. Pooled trusts vary in how they define allowable distributions, and mental health care may not always be spelled out. This is easier to clarify upfront than to fight for later.
The trust is not a fast tool. Every distribution goes through the trustee, who has a legal obligation to evaluate whether the expense is appropriate under the trust’s terms. That process exists to protect the beneficiary, and it takes time - days to weeks, depending on the trustee, the documentation required, and how familiar they are with mental health distributions. For planned, predictable expenses, that timeline is manageable. When there’s a mental health crisis, it could cause problems.
This doesn’t disqualify the trust. It means the setup work matters. Talking to your trustee now - about what mental health distributions look like, what documentation they’ll need, and how quickly they can process an urgent request - is planning that makes the trust functional when it matters. Trustees who have had that conversation in advance may be able to move faster than those who haven’t.
What the ABLE account can do
An Achieving a Better Life Experience (ABLE) account works differently. It’s a savings account, and the account holder - or an Authorized Legal Representative - can access funds directly, without going through a trustee. For urgent needs, speed matters.
Mental health treatment qualifies as a disability-related expense under the ABLE Act. That matters for three reasons: the money grows tax-free, the account balance is a protected asset for SSI purposes, and distributions for qualified expenses don't count as income. Annual contributions are capped at $20,000, and family members can contribute within that limit - not just the account holder.
In situations where there’s the possibility of self-pay for therapy and medication, the ABLE account could be a lifesaver. This makes it worth funding intentionally - getting there isn't always easy, and most families haven't built the balance up to the point where it can function as a meaningful buffer. Small periodic contributions add up, but they may not add up fast enough to cover a course of treatment with a specialist, let alone something more intensive.
How the two tools work together
If you have both a trust and an ABLE account, the practical division of labor could look something like this: use the ABLE account for urgent, time-sensitive mental health expenses while the trustee processes a distribution from the trust. The ABLE account bridges the gap. The trust handles larger or ongoing costs. That only works if the ABLE account has enough in it to actually bridge something. One way to build that buffer intentionally is to work with your trustee on an annual distribution to the ABLE account - early in the year, before a crisis makes it urgent. It requires planning, but it's the kind of conversation worth putting on the calendar.
For families without a trust - which may be more common among families who don't have an IDD waiver because the planning pathway is less defined - the ABLE account could be carrying more of the weight. That's a lot to ask of one tool. If your family member has ongoing mental health expenses that Medicaid doesn't fully cover, a Special Needs Trust is worth looking into. The ABLE account can handle the urgent and the everyday. The trust is built for the long haul.
The gap isn’t the tools - it’s the setup
Unfortunately, many individuals with mental health conditions, and the families supporting them, haven't done any formal disability planning. They're overwhelmed, living in the moment, and I don't recall seeing any financial planning firms identifying this as their niche or actively marketing to them - unlike 'Special Needs', which has historically meant IDD.
Even families who have done some planning often haven't had the specific conversations that make the tools work when they're needed - with their attorney about what the trust actually covers, or with their trustee about how quickly a mental health distribution can move. If you or your family member has significant mental health needs but no IDD diagnosis, finding professionals who understand your specific benefit picture is harder and more important.
Whatever your situation is, here are a few things worth looking into. If you have a trust, ask your attorney whether mental health expenses are clearly within the distribution standards - not assumed, but explicit. Then call your trustee and ask what documentation they need and how quickly they can process an urgent request. If you have an ABLE account, look at the balance and be honest with yourself about whether it could cover two to four months of out-of-pocket mental health care if Medicaid didn’t cover the provider you needed. If not, building it toward that level is a concrete goal worth setting. If you don’t have an ABLE account, open one. Having it in place before you need it is the whole point.
If you’re in the situation where a waiver was never available to your family member, the first step is understanding exactly what Medicaid does cover in your state for adults with mental health conditions - and where the coverage ends. That baseline tells you what the financial planning actually needs to bridge.
What planning doesn’t fix
I understand there are not enough qualified providers - I’ve lived this. Even with a funded ABLE account and a trustee who processes distributions quickly, families in parts of the country with thin dual-diagnosis provider networks are going to struggle to find the right professional. That’s a systemic problem that no individual plan solves.
Planning can help you make sure money isn't the barrier when you finally find the right provider. Given how hard that search can be, not having the financial piece ready when you get there is a gap worth closing now.
