Getting Your Power Wheelchair Approved: A Guide to Medicare, Medicaid, and Private Insurance
If you or a loved one needs a power wheelchair, the equipment itself is usually the easy part — the harder part is convincing an insurance company to pay for it. Every payer, whether it's Medicare, a state Medicaid program, or a private health plan, requires proof that the device is medically necessary before it will approve coverage.
That proof-gathering process can feel overwhelming: face-to-face exams, written orders, mobility evaluations, prior authorization, specific billing codes, and strict deadlines. Miss one piece and the whole request can be delayed or denied.
To help, we put together a free, downloadable guide that walks through exactly what each type of insurance requires, in plain language. It covers:
The medical-necessity standard every insurer uses to evaluate a power wheelchair request
Step-by-step approval processes for Medicare, Medicaid, and commercial insurance
A complete documentation checklist you can bring to your doctor's appointment
The most common reasons claims get denied, and how to appeal successfully
The One Standard Every Insurer Uses: "Medical Necessity"
Regardless of who is paying — Medicare, Medicaid, or a private plan — approval comes down to one central question: is this power wheelchair medically necessary for you to complete everyday activities in your home? Insurers are not asking whether a power wheelchair would be convenient or would improve your quality of life in general. They are asking a narrower question, and your documentation needs to answer it directly.
Across nearly all payers, medical necessity for a power wheelchair generally requires showing all of the following:
A significant mobility limitation that prevents you from safely completing daily activities in your home — such as toileting, bathing, dressing, grooming, or getting to the kitchen — within a reasonable amount of time.
That a cane or walker cannot safely resolve the problem.
That you do not have the strength, endurance, or coordination to self-propel a manual wheelchair for those same activities.
That you (or a willing, available caregiver) can safely operate the power wheelchair.
That your home has enough space and appropriate surfaces for the device to be used.
That the wheelchair will actually be used inside the home to complete daily activities — not only for outings or appointments.
That last point trips up a surprising number of applications. Documentation that focuses on getting to doctor's appointments or getting around town, without addressing mobility inside the home, is one of the most common reasons requests are denied. Every conversation with your doctor should center on what is hard to do at home.
How the Three Payer Types Compare
Medicare
Federal program (CMS). Coverage is based on "medical necessity" under national Local Coverage Determination (LCD) criteria. A face-to-face exam is required within 6 months before the order. Prior authorization is required for most power wheelchairs. Typical review time: 5 business days, not to exceed 7 calendar days (2 business days if expedited). Appeals path: redetermination → reconsideration → ALJ hearing → further review.
Medicaid
State-run, federal/state funded. Coverage is based on "medical necessity" under state-specific rules. A face-to-face exam is required in nearly all states. Prior authorization is required in most states. Typical review time: 30–90 days, varies by state. Appeals path: state fair hearing process.
Commercial / Private Insurance
Provided by private insurance companies. Coverage is based on "medical necessity" under each plan's own policy. A face-to-face exam is usually required. Prior authorization is required by most plans. Typical review time: up to 15 days standard / 72 hours urgent (some plans, such as ACA marketplace plans, must decide within 7 days). Appeals path: internal appeal → external review (IRO).
Medicare: Step-by-Step
Medicare Part B covers power wheelchairs as durable medical equipment when criteria are met, but the process is document-heavy and closely timed. Here is the sequence in order.
Step 1 — Face-to-face examination
Your physician must examine you in person within the 6 months before the wheelchair is ordered. The visit must address your mobility limitations, why a cane or walker will not work, and why a manual wheelchair is not sufficient. A telehealth visit or a visit focused only on an unrelated issue typically will not satisfy this requirement.
Step 2 — Standard Written Order (SWO)
After the face-to-face exam, your physician issues a written order for the base equipment. This order cannot come before the exam — Medicare requires the exam to establish the need first.
Step 3 — Specialty evaluation (for higher-level chairs)
For more advanced power wheelchairs (Medicare's "Group 2" chairs with power seating options and "Group 3" chairs), a physical therapist, occupational therapist, or other qualifying clinician must complete a specialty mobility evaluation documenting exactly why those specific features are medically necessary for you.
Step 4 — Prior authorization
Most power wheelchairs require prior authorization before delivery. Your DME supplier submits your medical records, the written order, and the mobility evaluation to Medicare for review. Medicare typically responds within about 5 business days, and no later than 7 calendar days, for a standard request (2 business days for expedited requests). If the request is approved, you'll receive a unique tracking number — delivery without that number is one of the most common causes of automatic denial.
Step 5 — Home assessment and delivery
Before or at the time of delivery, your supplier confirms your home has adequate space and surfaces for the chair to be used safely. Delivery must occur within 120 days of the face-to-face exam and within 6 months of prior authorization approval.
What it costs
After you meet your Part B deductible, you typically pay 20% of the Medicare-approved amount, as long as your supplier accepts Medicare assignment. Choosing a supplier that is Medicare-enrolled and participates in assignment protects you from being billed above the approved amount. If you have a Medicare Advantage plan, contact your plan directly, since rules and networks differ from Original Medicare.
Medicare timing cheat sheet
Face-to-face exam: within 6 months before the written order. Medical records submission: within 45 days of the face-to-face exam. Delivery: within 120 days of the face-to-face exam. Delivery after prior authorization approval: within 6 months. Standard prior authorization decision: 5 business days (no later than 7 calendar days); 2 business days if expedited.
Medicaid: Step-by-Step
Medicaid also covers power wheelchairs as medically necessary equipment, but because Medicaid is administered by each state, the specific rules, forms, and timelines vary. A few things are true almost everywhere:
• You will need a face-to-face examination and physician certification, similar to Medicare.
• A functional/mobility assessment is required showing why a manual wheelchair will not work.
• Prior authorization is required in most states, and review typically takes 30 to 90 days — plan ahead.
• Many states weigh community integration heavily, especially under Home and Community-Based Services (HCBS) waivers, so documentation that addresses moving safely within the home and community can matter more than it does for Medicare.
• If you're enrolled in both Medicare and Medicaid ("dual eligible"), Medicare is typically billed first and Medicaid may cover remaining costs or equipment Medicare doesn't fully cover.
Because requirements differ by state — some states require competitive bidding among suppliers, others emphasize specific functional assessment forms — it's worth calling your state Medicaid office or your DME supplier early to confirm exactly what documentation your state requires before you schedule the physician visit.
Private / Commercial Insurance: Step-by-Step
Private insurance plans generally follow a similar overall shape to Medicare and Medicaid, but the specific forms and definitions of "medical necessity" are set by each individual plan, so always check your plan's specific policy.
Get a face-to-face evaluation. Your physician documents your mobility limitations in person — this cannot be replaced by a phone call or old notes.
Complete a Certificate of Medical Necessity (CMN), if your plan uses one. Some private plans still require a CMN-style form, completed by your physician, documenting your diagnosis and functional limitations (Medicare itself discontinued CMN forms in 2023, so this mainly applies to private payers now).
Gather supporting records. Physician notes, relevant test results, and documentation of mobility aids you've already tried (cane, walker, manual chair) all strengthen the request.
Confirm your supplier is in-network. Using an out-of-network DME supplier can result in denial or much higher out-of-pocket costs — verify network status and accreditation before ordering equipment.
Submit for prior authorization before ordering. Ordering the equipment before authorization is approved is one of the fastest ways to have an otherwise-valid claim denied outright.
Under the federal floor for most employer-sponsored plans, standard prior authorization decisions are generally required within 15 calendar days (72 hours for urgent requests). Some plans move faster than that floor: ACA marketplace, Medicare Advantage, and Medicaid managed care plans must now decide standard requests within 7 calendar days under a newer federal rule. Check your plan's Summary Plan Description for its exact timeline. Many states also have a "deemed approved" rule: if the insurer misses its deadline, the request is automatically approved.
Universal Documentation Checklist
Regardless of payer, gathering the following before your appointment will cover nearly everything an insurer is likely to ask for. Bring this list to your physician visit.
• Recent face-to-face examination note (within the last 6 months) addressing mobility limitations specifically
• Physician's written order / prescription for a power wheelchair (signed and dated)
• Diagnosis and history explaining the underlying medical condition
• Documentation that a cane or walker is not sufficient
• Documentation that a manual wheelchair is not sufficient (strength, endurance, or coordination limitations)
• Specialty mobility evaluation from a PT/OT, for higher-level power chairs
• Description of specific daily activities affected at home (bathing, dressing, toileting, meal prep, moving between rooms)
• Confirmation you or a caregiver can safely operate the device
• Home assessment confirming adequate space and surfaces
• Certificate of Medical Necessity (CMN), if your payer requires one (Medicare stopped using CMN forms in 2023; some private plans still do)
• Correct HCPCS billing/product codes for the specific chair and features
• Proof of Medicare/Medicaid enrollment or in-network status for your DME supplier
Common Reasons Claims Get Denied
Knowing what trips up other applications is the best way to avoid the same mistakes:
• Missing or outdated face-to-face exam — a visit older than the payer's window, or one that doesn't specifically address home mobility.
• Documentation that focuses on transportation or appointments rather than daily activities inside the home.
• Incomplete paperwork — missing signatures, missing product codes, or records that don't clearly connect the diagnosis to the need for a power (rather than manual) wheelchair.
• Ordering equipment before prior authorization is approved.
• Using a supplier that isn't Medicare-enrolled, Medicaid-approved, or in-network for your private plan.
• Missing submission deadlines — for example, Medicare requires medical records within 45 days of the face-to-face exam and delivery within 120 days.
• Requesting a replacement chair without documenting a changed medical condition or that the original chair is damaged beyond repair.
If You're Denied: How to Appeal
A denial is not the end of the road — a large share of power wheelchair denials are overturned on appeal, especially when the appeal directly addresses the stated reason for denial rather than simply resubmitting the same paperwork.
Step 1 — Read the denial letter closely
The letter must state the specific reason for denial. That reason is your roadmap — your appeal needs to directly answer it, not just restate that you need the chair.
Step 2 — Call your insurer
Ask exactly what documentation would resolve the denial. This one call can save weeks of back-and-forth.
Step 3 — Strengthen the medical record
Work with your physician (and PT/OT, if applicable) to add a detailed letter of medical necessity that speaks specifically to your daily, in-home mobility challenges — with concrete examples, not general statements.
Step 4 — File your appeal in writing, and on time
Private insurance: you typically have 180 days to file an internal appeal. Medicare: you have 120 days to request a redetermination. Medicaid: your state's deadline will be listed in the denial notice — file promptly.
Step 5 — Escalate if needed
If the internal appeal is denied, you can generally request an independent, binding external review (private insurance), a Medicare reconsideration and, if necessary, a hearing before an Administrative Law Judge, or a state fair hearing (Medicaid). These outside reviewers are independent of the insurer and can overturn the original decision.
Keep a paper trail
• Log every call: date, who you spoke with, and what they said.
• Save copies of everything you submit and every letter you receive.
• Follow up in writing after phone calls to confirm what was discussed.
• Ask your DME supplier to help track prior authorization and appeal status — this is part of what a good supplier does for you.
