You or someone you love has just been prescribed a wheelchair, walker, oxygen equipment, or a CPAP machine, and the first real question is: does Medicare cover durable medical equipment? The short answer is yes, but coverage depends on meeting specific requirements, working with an approved supplier, and having the right documentation in hand. At MacPherson’s Medical Supply, we’ve been helping South Texas families sort through exactly these questions since 1940. New to Medicare, or helping an aging parent in the Rio Grande Valley get the equipment they need? This guide walks you through what Medicare typically covers and how to get the process started.
What Makes Equipment “Durable” in Medicare’s Eyes
Medicare Part B covers durable medical equipment, but not every piece of medical equipment qualifies. To be covered, equipment must be durable enough to withstand repeated use and last at least three years. A Medicare-approved doctor must also have prescribed it due to an illness or injury, establishing medical necessity. The equipment must be used in your home rather than in a hospital or skilled nursing facility, and it must serve a clear medical purpose.
That last point trips people up more than they expect. Even a doctor’s recommendation won’t get something covered unless it has a defined medical function. An air conditioner, for example, rarely qualifies, even with a doctor’s note.
Wheelchairs and Power Scooters
Medicare Part B typically covers manual wheelchairs, power wheelchairs, and mobility scooters for patients who have difficulty walking due to a medical condition. Your doctor must document that you have a mobility limitation significantly affecting your ability to participate in daily activities at home, and that a wheelchair or scooter is necessary for home use, not merely for getting around outside.
Our medical supply store carries a range of mobility options and can help you and your care team identify what fits your situation. We also handle complex rehabilitation equipment for patients with more involved mobility needs.
Walkers and Standard Mobility Aids
Walkers, canes, and crutches also fall under Medicare Part B DME coverage once prescribed by a doctor. These are among the most commonly covered items in the RGV, particularly for patients recovering from surgery or managing a progressive condition. Coverage applies to standard walkers, wheeled walkers, and rollators, as long as the prescription and documentation support the medical need.
Oxygen Equipment and Accessories
For patients with chronic obstructive pulmonary disease (COPD), heart failure, or other conditions affecting blood oxygen levels, Medicare Part B covers oxygen equipment and the accessories that go with it. This typically includes oxygen concentrators, portable oxygen units, tubing, and masks.
To qualify, your doctor must document that your blood oxygen levels fall below a certain threshold, usually confirmed through a blood test or pulse oximetry reading. Medicare generally covers rental of the equipment rather than outright purchase, and coverage may continue as long as medical necessity is established.
Our respiratory team at MacPherson’s works closely with prescribing physicians across Harlingen and the wider Valley to make sure the right equipment reaches patients as smoothly as possible.
CPAP Machines for Sleep Apnea
Does Medicare cover durable medical equipment like CPAP machines? Yes, and this is one of the most common requests we see. Medicare Part B covers CPAP therapy for patients diagnosed with obstructive sleep apnea through a qualified sleep study. Coverage typically includes the machine, tubing, and a mask or interface.
There is a trial period involved. Medicare initially covers a 13-week trial, after which your doctor must confirm that you’re using the therapy consistently and benefiting from it for coverage to continue.
How Prescription and Documentation Work
Before Medicare will cover any DME, two things must be in place. First, your doctor must write a prescription and provide documentation showing the equipment is medically necessary for home use. Second, you must obtain the equipment from a Medicare-approved supplier who accepts Medicare assignment, meaning they agree to Medicare’s approved payment amount rather than billing you above that rate.
Skipping either step can result in a denied claim, so confirming both before moving forward is worth the effort. MacPherson’s Medical Supply is a Medicare-approved supplier, and we can walk you through exactly what documentation your doctor’s office needs to provide.
Your Share of the Cost
Once you’ve met your Part B deductible for the year, Medicare covers 80% of the Medicare-approved amount for DME. You are responsible for the remaining 20%. A Medicare Advantage plan operates under different coverage rules and cost-sharing arrangements than Original Medicare, so checking with your plan directly is the right move.
Other Equipment Medicare Commonly Covers
Beyond mobility and respiratory equipment, Medicare Part B covers a broad range of DME. Hospital beds, nebulizers, blood glucose monitors, test strips, continuous glucose monitors, infusion pumps, suction pumps, traction equipment, and certain prosthetics and orthotics all qualify. Our medical supply services span many of these categories, including custom orthotic bracing and home and vehicle accessibility equipment.
Why Working With a Local, Approved Supplier is Important
A local, Medicare-approved supplier who knows the Valley makes the whole process go more smoothly. We coordinate directly with your doctor’s office, verify your coverage, and make sure the right paperwork is in place before equipment is provided. That’s been our approach for over 80 years, and it’s the reason families across Harlingen and South Texas keep coming back.

Getting Started Is Simpler Than You Think
Does Medicare cover durable medical equipment like wheelchairs, walkers, oxygen equipment, and CPAP machines? In most cases, yes — and the process of getting covered is more straightforward than many patients expect. The keys are a proper prescription, documentation of medical necessity, and a Medicare-approved supplier who knows what they’re doing.
At MacPherson’s Medical Supply, we’re proud to be a trusted local resource for Medicare patients and their families. Ready to take the next step? Get in touch or request a quote — we’re here Monday through Friday, 8am to 5pm, and happy to help.
Does Medicare cover durable medical equipment for home use only?
Yes. Medicare Part B covers DME used in your home or primary place of residence. Equipment used in a hospital or skilled nursing facility falls under Medicare Part A. Patients who divide their time between two homes can generally still receive coverage as long as one location is the primary residence.
Does my doctor have to be Medicare-approved to prescribe covered DME?
Yes. The physician who prescribes your equipment must be enrolled in Medicare and eligible to order DME. A doctor who is not enrolled may trigger a coverage denial even for equipment that would otherwise qualify. Confirming enrollment with your doctor’s office before the order is submitted is a smart precaution.
How long does it take to get DME approved through Medicare?
Timing varies depending on the type of equipment and how quickly documentation is submitted. Straightforward items like walkers may be processed quickly, but power wheelchairs or oxygen equipment may require additional review. An experienced supplier who handles Medicare paperwork regularly helps avoid delays.
What if I have both Medicare and Medicaid?
Patients who qualify for both Medicare and Medicaid — sometimes called dual eligibility — may have Medicaid cover costs that Medicare does not, including the 20% cost share. MacPherson’s accepts Medicare, Medicaid, VA, TriCare, and most major insurance plans, so our team can help sort out how your coverage works together.
