One of the most-loved posts in the disability threads we studied is just a woman crying because the wheelchair got approved. The comments understood: behind every approval is months of assessments, denials, resubmissions, and a vocabulary test nobody handed you the study guide for. Here's the study guide, for wheelchairs specifically and for the durable medical equipment (DME) machine generally.
The one phrase that decides everything: in the home
Medicare's mobility benefit is built on a narrow question: can you safely get around inside your home and complete daily living activities (bathing, dressing, toileting, transferring, meals) without this equipment? "I can't do my grocery shopping" and "I can't manage the park with my grandkids," however true, are denial language, because Medicare classifies outside-the-home needs as convenience. The same limitation reframed ("cannot carry a plate from stove to table while using a walker," "cannot reach the bathroom safely at night") is approval language. This isn't gaming; it's answering the question the reviewer is legally required to ask, and most legitimate needs have an in-home expression that the chart simply never captured.
The sequence, step by step
- The face-to-face exam: a visit with your doctor (or NP/PA) specifically about mobility, producing a written order. The documentation must walk the ladder: why a cane fails, why a walker fails, why (for power equipment) a manual chair fails (arm strength, endurance, cardiopulmonary limits), all tied to in-home ADLs. Book the visit as "mobility evaluation," bring your symptom and fall log, and say the ADL specifics out loud so they land in the note.
- The right equipment class: standard manual chair, lightweight, scooter (requires ability to transfer and steer), standard power chair, or complex rehab (tilt, custom seating) which adds a specialty evaluation with an assistive technology professional. Let the clinical team drive the class; underclaiming wastes the once-per-five-years window, and overclaiming invites denial.
- Prior authorization for power equipment: the supplier submits to the DME contractor, decided within about 10 business days. A "non-affirmed" decision names what's missing and allows unlimited resubmission, so treat round one as a draft review, not a verdict.
- The home assessment: for power equipment, someone verifies the home physically accommodates it (doorways, turning radii, surfaces). Clear the obvious obstacles before the visit; "home cannot accommodate" is a real denial reason with a furniture-moving solution.
- A Medicare-enrolled supplier that accepts assignment: ask both questions explicitly, because a non-participating supplier can charge above Medicare's rate and the difference is yours.
The money: rental, ownership, repairs
- The 13-month capped rental: Part B pays 80% of the monthly rental rate, you pay 20% coinsurance (after deductible), and at month 13 the equipment becomes yours. Medigap absorbs the 20%, which matters over a five-figure complex chair.
- Repairs and maintenance: during rental, the supplier's problem; after ownership, Medicare covers repairs (80/20) while the equipment remains medically necessary, including replacement parts and labor. Batteries are the perennial fight; they're covered, and the claim occasionally needs the same in-home necessity language as the original chair.
- Replacement: generally every five years, or sooner if your condition changes or the equipment is damaged beyond repair. Document condition changes as they happen; the five-year clock bends to medical need with a chart to point at.
- On Medicare Advantage: the criteria mirror Original Medicare, run through the plan's own prior auth, with the usual dynamics: more denials up front, 80%+ overturn rates for those who appeal.
Beyond Medicare: the parallel doors
If Medicare's box doesn't fit (you need the chair primarily for work or community life, or you're not on Medicare): Medicaid covers mobility equipment with broader standards in many states (waivers included), vocational rehabilitation agencies fund equipment tied to employment, the VA runs its own generous DME system for enrolled veterans, commercial plans follow prior-auth playbooks with plan-specific criteria, and condition organizations (ALS, MS, MD associations) run equipment loan closets that bridge the months the paperwork takes. Loan closets deserve more fame generally: most areas have one, and they solve the today problem while the system solves the forever problem.
How Kite handles this
Kite fights the paper war: it preps the face-to-face visit with the in-home ADL language your case needs, tracks the prior-auth clock and names every gap from a non-affirmation, drafts the doctor's addendum request and the appeal, and logs each supplier conversation, so the ugly-cry at the end is the approved kind. Text Kite to start.
