1. The Big Rule: It Must Be Durable Medical Equipment (DME)
Medicare uses a specific definition for what qualifies as covered equipment, and understanding this framework is your key to knowing what you can get. Durable Medical Equipment must serve a medical purpose (not just convenience), withstand repeated use, be appropriate for home use, and have an expected lifespan of at least three years. This distinction matters because plenty of helpful health-related items don't meet these criteria and therefore aren't covered, no matter how useful they might be.
The "medical purpose" requirement means your doctor must prescribe the equipment to treat or manage a diagnosed medical condition. You can't just decide you'd like a hospital bed because it seems comfortable—your physician needs to document why it's medically necessary for your specific health situation. The equipment must help you function better at home or manage your condition more effectively. A wheelchair qualifies because it enables mobility for someone who can't walk safely; a massage chair doesn't qualify even though it might help your back pain, because Medicare considers it comfort equipment rather than medically necessary.
The durability aspect eliminates consumable supplies and disposable items from coverage. Bandages, gloves, incontinence supplies, and similar items that get used up don't qualify as DME even when medically necessary. This can create frustration when you need ongoing supplies to manage chronic conditions, but Medicare draws this line to limit coverage to equipment with long-term utility. Understanding this distinction helps you know what to request versus what you'll need to budget for separately.
2. Mobility Equipment: From Walkers to Wheelchairs
Medicare covers a wide range of mobility devices that help you move safely around your home and community. Standard walkers, rolling walkers, canes (including quad canes), and crutches all qualify when your doctor determines you need assistance with balance or walking. Manual wheelchairs and power wheelchairs are covered when you have significant mobility limitations that prevent you from functioning without them. The approval process for power wheelchairs is more stringent, requiring documentation that you can't operate a manual wheelchair but can safely control a powered device.
The coverage extends beyond basic mobility to include wheelchair accessories like cushions, arm and leg rests, and specialized wheels when medically necessary. If you need a wheelchair, Medicare understands that proper accessories aren't luxuries—they're essential for preventing pressure sores, maintaining proper positioning, and ensuring the wheelchair actually functions for your needs. Seat lift mechanisms (the part that physically lifts you, not the entire chair) qualify for coverage when you have severe arthritis or neuromuscular disease preventing you from standing up unassisted.
Transport chairs—those lightweight wheelchairs designed for someone to push you—typically aren't covered because Medicare considers them primarily for caregiver convenience rather than patient mobility. This distinction frustrates many families, but Medicare's position is that if you can't propel yourself, you need a standard wheelchair or power wheelchair rather than a transport chair. The nuance matters when you're ordering equipment, as choosing something that doesn't meet Medicare's definition means you'll pay full price instead of the 20% coinsurance you'd pay for covered equipment.
3. Hospital Beds and Patient Lifts: Serious Needs, Substantial Coverage
When mobility becomes severely limited, Medicare covers hospital beds for home use, recognizing that adjustable positioning can be medically essential. The coverage includes semi-electric and fully electric hospital beds when your doctor documents that you have a medical condition requiring bed positioning (like difficulty breathing when lying flat) or that getting in and out of a regular bed is medically contraindicated. Side rails, mattresses, and over-bed tables are considered accessories to the hospital bed and are covered when the bed itself is approved.
Patient lifts represent another category of substantial equipment Medicare covers when medically necessary. If you can't safely transfer from bed to wheelchair, or from wheelchair to toilet, and your condition isn't expected to improve, Medicare may cover a patient lift system. These devices dramatically reduce caregiver injury risk while enabling safer transfers for the patient. The coverage typically extends to both manual and powered lift systems, with the choice depending on your specific needs and your caregiver's physical abilities.
Trapeze bars and grab bars attached to hospital beds qualify for coverage as bed accessories, providing support for repositioning yourself in bed or transferring to a wheelchair. However—and this is a critical distinction—grab bars permanently installed in your bathroom walls aren't covered because they're considered home modifications rather than DME. Medicare covers equipment that moves with you, not improvements to your house. Understanding this boundary helps you know what to request through Medicare versus what you'll need to install and pay for independently.
4. Respiratory Equipment: Breathing Easier at Home
For people with chronic respiratory conditions, Medicare provides substantial coverage for equipment that supports breathing and oxygen delivery. Home oxygen equipment and supplies are covered when your blood oxygen levels fall below specific thresholds documented by your doctor. This includes oxygen concentrators, portable oxygen systems, oxygen tanks, and related supplies like tubing and masks. The coverage is comprehensive because Medicare recognizes that adequate oxygenation isn't optional—it's essential for surviving and functioning.
Nebulizers and related medications prescribed for respiratory conditions also qualify for coverage under Medicare Part B. If you have asthma, COPD, or other conditions requiring nebulizer treatments, Medicare covers both the machine and the medication used in it (though the medication might be covered under Part B or Part D depending on how it's administered). Replacement supplies like nebulizer kits and filters are covered when you need them at medically appropriate intervals.
CPAP and BiPAP machines for sleep apnea fall under Medicare's respiratory equipment coverage, but the approval process requires a sleep study documenting your condition and demonstrating that CPAP therapy is medically appropriate. Medicare also covers replacement supplies including masks, tubing, and filters on a schedule based on expected wear. The catch is that you typically need to demonstrate compliance—actually using the machine—to continue receiving replacement supplies. The logic is that if you're not using the equipment, you don't need replacement supplies, which makes sense even if the monitoring feels intrusive.
5. Diabetes Equipment and Continuous Glucose Monitors
Medicare covers essential diabetes management equipment under Part B, recognizing that proper blood sugar monitoring prevents complications that would cost the system far more to treat. Blood glucose monitors, test strips, lancets, and lancing devices are all covered, though specific quantities and frequency depend on whether you're insulin-dependent and what your doctor prescribes. Insulin pumps and related supplies qualify for coverage when medically necessary, though the approval process requires documentation of your diabetes management needs.
Continuous glucose monitors (CGMs) represent newer technology that Medicare began covering in 2017, but with specific requirements. You must have diabetes, be insulin-dependent, test your blood sugar at least four times daily, and have a doctor's prescription specifically for a CGM. The coverage marked a significant policy shift, acknowledging that continuous monitoring prevents dangerous blood sugar swings better than periodic testing. However, not all CGM brands are Medicare-approved, so you'll need to ensure your preferred device is on Medicare's covered list before assuming it's paid for.
The coverage extends to therapeutic shoes for people with diabetic peripheral neuropathy and evidence of foot complications. You're limited to one pair of custom-molded shoes per year or one pair of extra-depth shoes with three pairs of inserts. This benefit often goes unused because many beneficiaries don't realize it exists or don't think to ask their doctor about it. If you have diabetes with any foot problems—numbness, previous ulcers, poor circulation—asking your doctor about therapeutic shoes could prevent serious complications down the line.
6. Bathroom and Toilet Safety Equipment
Commode chairs—portable toilets for people who can't safely reach a bathroom—are covered when medically necessary. These aren't the most glamorous pieces of equipment, but they're essential for maintaining dignity and safety when mobility becomes severely limited. The coverage includes both bedside commodes and shower/commode chairs that allow safe bathing while seated. Medicare recognizes that bathroom activities pose serious fall risks, and equipment preventing those falls serves a legitimate medical purpose.
Raised toilet seats and toilet safety frames (the grab bars that surround your toilet) qualify for coverage when you have severe arthritis, hip replacement surgery, or other conditions making it difficult to lower yourself onto or raise yourself from a standard toilet. These items dramatically reduce fall risk during bathroom use, one of the most dangerous activities for seniors with mobility limitations. The approval process is typically straightforward when your doctor documents your mobility restrictions.
However, permanent bathroom modifications like grab bars bolted to walls or walk-in tubs don't qualify as DME because they're considered home improvements rather than medical equipment. This distinction creates frustration because the permanently installed safety features might work better than portable equipment, but Medicare's rules are clear: the equipment must be removable and able to move with you. You can't take wall-mounted grab bars when you move houses, so Medicare won't pay for them even though they serve an identical safety function to portable safety frames.
7. Infusion Pumps and Home Health Technology
When you need intravenous medications at home, Medicare covers infusion pumps and related supplies. This equipment allows people to receive antibiotics, pain management, chemotherapy, and other medications intravenously without staying in a hospital or visiting a clinic daily. The coverage requires a doctor's order specifying the medication, dosage, and medical necessity for home infusion therapy. External infusion pumps and supplies like IV poles, tubing, and catheters are all covered when prescribed as part of a home infusion plan.
Parenteral and enteral nutrition equipment—feeding pumps and supplies for people who can't eat normally—are covered when medically necessary. If you have a condition preventing normal eating and digestion, Medicare will cover the equipment needed to deliver nutrition directly to your stomach or bloodstream. This includes the pumps, feeding tubes, specialized formulas, and related supplies. The coverage can be life-sustaining for people with severe gastrointestinal conditions, cancer, or neurological disorders affecting swallowing.
More recently, Medicare has expanded coverage to include certain types of home health monitoring equipment for specific conditions. Remote patient monitoring devices that measure and transmit health data like blood pressure, weight, or blood oxygen levels may be covered when your doctor prescribes them as part of a chronic care management plan. This represents an evolution in Medicare's thinking, recognizing that preventing complications through monitoring costs less than treating emergencies after they occur.
8. What Medicare Definitely Won't Cover
Understanding what's excluded helps you avoid denied claims and plan your budget appropriately. Medicare doesn't cover equipment used primarily for comfort or convenience rather than medical treatment—things like air conditioners, humidifiers, massage devices, or electric beds designed for comfort rather than medical positioning. Cushions or pillows for general comfort (as opposed to therapeutic positioning) don't qualify. Exercise equipment, even when recommended by your doctor for cardiac rehabilitation or physical therapy, typically isn't covered because Medicare expects you to exercise at a facility or find your own equipment.
Hearing aids represent one of the most significant coverage gaps, with Medicare providing no coverage for the devices themselves despite their obvious medical benefit. Medicare will cover diagnostic hearing tests and related medical treatment, but the actual hearing aids you need are entirely out-of-pocket. Vision aids including eyeglasses and contact lenses (except in specific post-surgical situations) are similarly excluded. These exclusions feel arbitrary given how directly hearing and vision affect health outcomes, but they reflect Medicare's original 1965 design before these technologies became as sophisticated and essential as they are today.
White noise machines for tinnitus, over-the-counter medications and supplies, alternative therapy devices, and most items you can buy at a pharmacy or general store aren't covered regardless of medical necessity. The distinction often comes down to whether something requires a prescription and is primarily used for treating medical conditions versus items anyone might buy for general wellness. When in doubt, check with Medicare directly or ask your equipment supplier whether an item qualifies before assuming coverage and ending up with an unexpected bill.
9. The 80/20 Rule and What You'll Actually Pay
Even when equipment is covered, understanding your financial responsibility matters enormously. Medicare Part B covers 80% of the Medicare-approved amount for covered equipment after you've met your annual Part B deductible ($240 in 2024). You're responsible for the remaining 20% coinsurance, which can add up significantly on expensive equipment. A $3,000 power wheelchair means you'll pay $600 after your deductible is met—substantial but far better than paying the full amount.
The "Medicare-approved amount" is key here because it's often far less than what suppliers would charge without insurance. Medicare negotiates rates with approved suppliers, and those negotiated prices are what your 20% coinsurance is calculated from. This is why using Medicare-approved suppliers matters—out-of-network suppliers can charge you the difference between Medicare's approved amount and their full price, dramatically increasing your costs. Always verify that your equipment supplier accepts Medicare assignment, meaning they agree to Medicare's approved amount as full payment.
Some equipment Medicare rents rather than purchases, particularly items needed temporarily during recovery. Hospital beds, wheelchairs, and other equipment prescribed for short-term use might be rented monthly rather than purchased. You'll pay 20% coinsurance each month, and after a certain period (typically 13 months), ownership transfers to you. For equipment you need long-term, this arrangement works fine. For short-term needs, rental can actually save money compared to purchasing equipment you'll only use briefly.
10. How to Actually Get Covered Equipment
The process starts with your doctor, who must document your medical need and write a prescription for specific equipment. Not all doctors are equally skilled at writing prescriptions that meet Medicare's documentation requirements, which can lead to denied claims even when equipment is legitimately needed. Make sure your doctor's prescription includes your diagnosis, the specific equipment needed, why it's medically necessary, and how long you'll need it. Detailed documentation upfront prevents frustrating denial battles later.
You'll need to use a Medicare-approved DME supplier—companies that have been vetted by Medicare and agreed to their payment terms and quality standards. You can search for approved suppliers in your area using Medicare's supplier directory online, or your doctor's office may work with specific suppliers they know are reliable. Beware of suppliers who pressure you to accept equipment you didn't ask for or who seem more interested in selling you things than meeting your specific medical needs—Medicare fraud in the DME space is common enough that healthy skepticism serves you well.
After receiving equipment, Medicare may require periodic documentation that you're still using it and that it remains medically necessary. This follow-up seems bureaucratic, but it prevents people from accumulating equipment they don't need while ensuring that those who do need equipment continue receiving necessary supplies and maintenance. Keep all paperwork related to your equipment, including delivery receipts, maintenance records, and your doctor's prescription. If Medicare ever questions a claim, thorough documentation is your best defense.
The Bigger Picture: Equipment as Independence
What strikes me most about Medicare's DME coverage is how it represents both genuine support and glaring gaps. The program recognizes that equipment enabling independence and managing chronic conditions at home costs far less than hospital care or nursing home placement. When you need mobility equipment, breathing support, or diabetes management devices, Medicare's coverage can be genuinely life-changing—the difference between struggling in isolation and maintaining active engagement with life.
Yet the arbitrary exclusions—hearing aids, home modifications, certain comfort equipment that could prevent medical crises—reveal how Medicare's 1965 design struggles to meet modern healthcare needs. The program wasn't built for a world where people routinely live decades with chronic conditions, managing complex care at home with technology that didn't exist when Medicare was created. The coverage you can access is substantial and valuable, but it's also incomplete in ways that leave many beneficiaries scrambling to fill gaps with personal funds many don't have.
Perhaps the most important realization is that Medicare coverage isn't automatic—it requires your active participation. You need to know what's available, work with your doctor to document medical necessity, choose approved suppliers carefully, and advocate for yourself when claims get denied despite legitimate needs. The equipment exists, the coverage is real, but accessing it demands persistence and knowledge. Are you willing to invest the time and energy to claim benefits you've literally paid for through decades of Medicare taxes? The equipment sitting unused in warehouses across America suggests many people aren't, often simply because they don't know what to ask for or assume it's more complicated than it actually is. Your health and independence might depend on being someone who does ask, who does persist, and who refuses to struggle unnecessarily when help is available.
