Key Takeaways

• Understand which durable medical equipment Medicare covers and what documentation is required.
• Avoid common errors—such as missing approvals or using out-of-network suppliers—to prevent unexpected costs.

Navigating Medicare’s rules for durable medical equipment (DME) can be daunting, especially after the PSHB transition. By understanding what is covered and where common mistakes occur, you can improve your chances of receiving the equipment you need, when you need it, with fewer headaches or delays.

What Is Durable Medical Equipment Coverage?

Definition of durable medical equipment

Durable medical equipment (DME) refers to items that help you manage a medical condition or recover at home. These items are designed for repeated use, serve a medical purpose, are generally not useful to someone who isn’t sick or injured, and are appropriate for home use. Examples include wheelchairs, walkers, hospital beds, and home oxygen equipment.

Medicare’s coverage criteria explained

For Medicare to cover DME, several requirements must be met:

• The equipment must be medically necessary, meaning prescribed by your doctor for a documented health reason.
• The equipment must be able to withstand repeated use over an extended period.
• It is primarily used at home.
• Medicare must recognize the item as eligible for coverage under its rules.
• The supplier must be enrolled with Medicare and agree to accept assignment (Medicare’s approved amount) as payment in full, except for your standard deductible and coinsurance.

Which Equipment Does Medicare Cover?

Commonly approved items explained

Some of the most frequently covered DME items under Medicare include:

• Wheelchairs (manual and powered) and scooters
• Walkers and canes
• Home oxygen equipment and related supplies
• Continuous Positive Airway Pressure (CPAP) devices for sleep apnea
• Hospital beds
• Patient lifts
• Blood sugar monitors and test strips (for those with diabetes)

Coverage can vary based on medical need and whether the supplier and equipment meet Medicare’s standards.

Are hearing aids or dental items included?

Generally, Medicare does not cover routine hearing aids, dental items (such as dentures), or eyeglasses for routine vision correction. However, there are exceptions for specific medical needs (for instance, glasses after certain types of cataract surgery), but these are the exception, not the rule. Always confirm coverage with Medicare or a trusted benefits advisor before making a purchase.

What Items Are Frequently Requested?

Wheelchairs and mobility aids

Wheelchairs, power scooters, walkers, and canes are commonly requested by Medicare beneficiaries, especially for those with mobility restrictions. Coverage is available only when your doctor certifies the need and the equipment is necessary for use in your home. You must have a face-to-face evaluation and a written prescription before ordering.

Home oxygen equipment

Home oxygen is often prescribed for chronic lung conditions. Medicare covers the rental and supplies if documentation supports the ongoing need, including test results such as arterial blood gases or pulse oximetry. Equipment must be provided by a Medicare-approved supplier.

Continuous Positive Airway Pressure (CPAP) devices

CPAP devices are essential for many with obstructive sleep apnea. Medicare may cover a three-month trial period if your doctor orders the device following a sleep study. Continued coverage requires documentation that you are using the device as prescribed and that symptoms are improving.

Hospital beds and patient lifts

Hospital beds and patient lifts help individuals who require home nursing support or have mobility challenges. A doctor’s documented medical need is vital, and the supplier must offer Medicare-approved equipment. Only beds with specific features (like adjustable height) meeting Medicare’s criteria are covered.

How Does the Coverage Process Work?

Medical necessity documentation basics

A common hurdle is failing to provide full documentation of medical necessity. Your doctor must clearly state why you need the item, aligning with Medicare’s guidelines. In some cases, recent office notes, test results, or a face-to-face evaluation are also required. Always confirm your paperwork is complete before ordering.

Supplier participation and assignment rules

Choose suppliers that participate in Medicare and agree to “accept assignment.” Assignment means they accept Medicare’s approved charge as payment in full for the covered equipment, with you only responsible for your share (the deductible and 20% coinsurance). Using non-participating suppliers can leave you responsible for extra charges or denial of coverage entirely.

What Mistakes Should I Avoid?

Ordering equipment before approval

A frequent error is ordering or receiving equipment before obtaining Medicare approval or completing all necessary paperwork. Always wait until your doctor has sent documentation and your supplier verifies Medicare’s approval before accepting delivery. Otherwise, you could be billed the full cost.

Using non-Medicare-participating suppliers

Not all DME suppliers are Medicare-approved. If you order from a supplier who doesn’t participate or accept assignment, you risk higher out-of-pocket costs or a denial of coverage. Confirm the supplier’s Medicare status before making any agreements.

Missing required documentation

Another common mistake is incomplete or missing documentation. If your prescription, doctor’s notes, or required test results are not submitted (or are incomplete), Medicare may delay or deny coverage. Work closely with your doctor and supplier to ensure all forms are thorough and accurate.

Is Durable Equipment Covered by PSHB?

PSHB overview after 2025 transition

After the 2025 transition, the Postal Service Health Benefits (PSHB) Program fully replaced FEHB for postal retirees. PSHB plans coordinate with Medicare, but the key rules for DME coverage remain tied to Medicare’s definitions and criteria. If you are enrolled in both PSHB and Medicare, Medicare acts as your primary payer for DME.

Medicare and PSHB coordination tips

Always confirm which plan pays first. Usually, Medicare pays primary; any eligible amount not covered can be sent to your PSHB plan for secondary review. To avoid delays, share both your Medicare and PSHB insurance information with your DME supplier. Carefully check whether your supplier is in-network for both plans.

How Can I Appeal a Denial?

Understanding the appeals process

If Medicare denies a DME claim, you have the right to appeal. Your initial denial notice explains both the reason for denial and the first appeal step. Typically, your appeal must be filed in writing within 120 days, including any new documentation or medical evidence supporting your case.

Next steps after an initial denial

If your appeal is unsuccessful, you may continue to the next level in Medicare’s appeals process, which can involve reviews by independent contractors or administrative law judges. Persistence and detailed documentation supporting your medical need are essential at each step.

Where Can I Find Trusted Assistance?

Non-governmental educational resources

National organizations like the State Health Insurance Assistance Program (SHIP) provide free, neutral educational resources to help you understand Medicare, DME coverage, and the PSHB transition. These organizations offer counseling and can help review your paperwork before submission.

Federal employee benefit counseling options

Federal retirees or near-retirees can also access expert guidance through independent employee benefit counselors. These professionals provide education and assistance regarding OPM rules, the PSHB transition, and coordination with Medicare—and can help you avoid costly errors in the process.
