Power Wheelchairs and Custom Seating in Montana: Coverage, Options, and Where to Start
When someone needs a power wheelchair, the equipment itself is only part of what they need. The harder part is often everything that surrounds it: figuring out what insurance will cover, finding a fit that works for the body and the medical situation, navigating waitlists and paperwork, and planning for the things insurance won’t cover at all. This article walks through how the system works, where it tends to break down, and what to do about it — with a focus on Montana specifically.
Why custom seating sometimes matters more than the chair itself
A power wheelchair from a catalog will work for many people who need one. But for people whose bodies have been changed by injury, surgery, or progressive conditions, a standard seat can become a problem on its own.
The clearest examples are people with skin or tissue that can’t tolerate ordinary pressure: someone recovering from full-thickness burns, someone with a spinal cord injury that has reduced sensation, someone post-surgery with a healing wound, or someone with advanced neurological conditions that affect posture and movement. For these situations, the cushion and the seating system aren’t accessories. They are part of the medical care. The wrong seating leads to pressure injuries, infections, and hospital readmissions. The right seating prevents those outcomes and lets the chair actually be used.
This is why custom-fitted seating exists as a separate clinical service, often delivered by certified Assistive Technology Professionals (ATPs) or seating specialists working alongside an occupational or physical therapist. They evaluate the person, take measurements, choose materials, and configure the chair to fit a specific body and a specific set of needs. It takes longer than ordering off the shelf. It also tends to last longer and prevent the secondary problems that come from poor fit.
What Medicare typically covers, and how the rules work
Medicare Part B covers durable medical equipment (DME) when a doctor prescribes it for use in the home and the person has a medical need that the equipment will address. Power wheelchairs are covered under this category, with several conditions.
The person must have a face-to-face evaluation with a physician who documents medical necessity. The chair must be ordered through a Medicare-enrolled supplier. The person typically pays 20% of the Medicare-approved amount after meeting the Part B deductible, with Medicare paying the other 80%. People with Medicare Advantage plans (Part C) have similar coverage, though the specific networks and prior authorization rules vary by plan.
Custom seating components — specialized cushions, back supports, positioning systems — can be covered as part of the wheelchair when there is a documented medical need. The “documented medical need” piece matters: a letter of medical necessity from the prescribing provider, often supported by a seating evaluation report from a certified specialist, is what unlocks coverage for components that cost more than the standard equivalent. Without that documentation, Medicare may approve a basic chair and deny the upgraded seating.
For people with both Medicare and Medicaid (sometimes called “dually eligible”), Medicaid often covers the 20% Medicare doesn’t, plus some items Medicare doesn’t cover at all. This varies by state. In Montana, Medicaid covers a broader range of DME than Medicare, including some home modifications and adaptive equipment that Medicare excludes — though eligibility and waiver rules narrow what’s actually accessible to a given person.
Where the coverage gaps tend to show up
A few patterns come up often enough to be worth knowing in advance.
Wheelchair ramps and home modifications
Medicare specifically excludes ramps, stairlifts, and most home modifications from DME coverage, even when the modification is what makes the wheelchair usable at home. This is one of the most common surprises families encounter. Montana Medicaid sometimes covers home modifications under specific waiver programs, but eligibility is narrow and the application process takes time. For people who don’t qualify, ramps usually have to be covered out of pocket, through nonprofit assistance, or built by community volunteers.
Custom-fit timelines
A custom-fitted power wheelchair from prescription to delivery commonly takes eight to sixteen weeks, sometimes longer. The evaluation, supplier ordering, insurance approval, and manufacturing each take time, and the steps run in series. People who need mobility support during this window often need a loaner or interim solution.
Replacement and repair
Medicare generally covers a power wheelchair every five years if medical need continues. Earlier replacement is possible but requires documentation of why the existing chair no longer meets the person’s needs. Repairs are covered, but finding a Medicare-enrolled repair supplier in rural Montana can be its own challenge.
Items considered “convenience” rather than medical necessity
Some accessories that genuinely improve quality of life — certain cushion upgrades, seat elevators on some models, specialized controls — may be denied as “not medically necessary” even when they meaningfully change what the chair can do. These denials are often appealable with the right documentation.
Where to start in Montana
Several Montana resources exist specifically to help with this. Each fills a different role.
is the state’s assistive technology program, based at the University of Montana Rural Institute. They maintain a wheelchair exchange where people can sometimes find equipment that’s been donated or returned, and they offer device demonstrations so people can try equipment before committing to a particular chair. Their database of available equipment is searchable online.
Certified seating and mobility clinics
at hospitals and rehabilitation centers in Billings, Missoula, Great Falls, and Helena can perform the seating evaluations needed for custom-fitted equipment. Major hospital systems usually have these clinics in-house or can refer to them. The evaluation itself is typically billed under therapy or DME codes, depending on the setting.
National-level providers
like National Seating and Mobility operate in Montana and specialize in the complex-rehab end of the wheelchair market. They are useful when local options are limited or when the chair being prescribed is at the more specialized end of what’s available.
Centers for Independent Living
Montana has four, covering the state geographically — provide independent living services and can sometimes help with equipment access, advocacy for insurance denials, and navigation support. They are non-medical organizations and don’t prescribe equipment, but they understand the systems and can be a useful guide. Contact information for all four is on our Resources page.
affiliates in Montana sometimes assist with ramps and accessibility modifications when Medicare and Medicaid don’t cover them. Coverage varies by affiliate. Some have ramp-building programs; others can connect families to volunteer crews.
Big Sky Independent Living Solutions (BSILS)
accepts donations of mobility and accessibility equipment and connects them with Montanans who need them at no cost. Inventory varies. When BSILS doesn’t have a specific item, we try to point people toward the resources above.
Practical first steps
For someone navigating this for the first time — for themselves or for someone they’re caring for — a few suggestions: Talk to the prescribing provider about whether a seating evaluation is appropriate, and if so, ask for a referral to a certified seating clinic. The evaluation itself is the document that often determines what coverage you can get.
Request a written letter of medical necessity that explains, in clinical terms, why standard equipment will not meet the person’s needs. The more specific the letter, the harder it is for an insurance reviewer to deny the request.
Document everything. Save copies of every prescription, evaluation report, denial letter, and appeal. Insurance navigation often comes down to producing the right paper at the right time, and having it organized matters more than people expect.
Plan for the timeline. If the equipment is needed in a specific window — for hospital discharge, for a return-to-home plan, for a child’s school year — start earlier than feels necessary. Custom equipment rarely arrives faster than expected.
Appeal denials. A meaningful share of initial DME denials are reversed on appeal, particularly when supported by a strong letter of medical necessity and a seating evaluation report. The appeal process has deadlines, so don’t let denials sit.
Ask for help. Insurance navigation is genuinely complicated, and most people who do it well had someone show them how the first time. Hospital social workers, case managers, occupational therapists, Centers for Independent Living, disability advocacy organizations, and programs like BSILS exist in part to be that someone.
