Key Takeaways

✓Check Medicare.gov's Supplier Directory before ordering any durable medical equipment to confirm your supplier is currently authorized to bill Medicare.
✓If your supplier loses its Medicare billing privileges, you are not automatically transferred to a new one — you must contact your doctor and arrange a new supplier yourself.
✓Under Original Medicare Part B, you pay 20 percent of the Medicare-approved amount for covered DME after your annual deductible ($240 in 2024), with no out-of-pocket maximum to protect you from large bills.
✓Report suspected DME fraud — such as equipment you never ordered or received — to the HHS Office of Inspector General hotline at 1-800-HHS-TIPS (1-800-447-8477).
✓Late enrollment in Part B carries a permanent 10 percent premium penalty for each full 12-month period you went without coverage, so resolving supplier disruptions quickly matters for your overall coverage continuity.

Medicare has banned hundreds of durable medical equipment companies from billing the federal program, a sweeping enforcement action by the Centers for Medicare and Medicaid Services aimed at cutting fraud and protecting beneficiaries. If your supplier is among those whose billing privileges have been revoked, you could face disrupted access to wheelchairs, oxygen equipment, diabetic supplies, and other medically necessary items covered under Part B.

Why CMS Is Revoking Supplier Privileges

CMS conducts ongoing audits of suppliers enrolled in the Medicare program. Revocations happen for several reasons: suppliers that cannot be located at their enrolled address, companies that bill for equipment never delivered, businesses with owners who have prior fraud convictions, and suppliers that fail unannounced site inspections. The agency has broad authority under the Social Security Act to remove bad actors from the program, and it has used that authority aggressively in recent years as DME fraud has cost the Medicare trust fund billions of dollars annually.

The practical effect for beneficiaries is immediate. Once a supplier's billing privileges are revoked, Medicare will not pay any claims that supplier submits — even for equipment you legitimately need and already use.

How Original Medicare Covers Durable Medical Equipment

Durable medical equipment falls under Medicare Part B, the outpatient and medical services portion of Original Medicare. Part B covers items that are medically necessary, prescribed by your doctor, and ordered from a Medicare-enrolled supplier. The cost-sharing structure is straightforward: after you meet the annual Part B deductible, Medicare pays 80 percent of the approved amount and you pay the remaining 20 percent.

There is no out-of-pocket maximum under Original Medicare. That 20 percent coinsurance has no annual cap, which means a prolonged need for expensive equipment — ventilators, power wheelchairs, or home oxygen — can add up to significant personal expense over time. A Medigap supplemental policy can cover that 20 percent, but only if you purchased one during your open enrollment window.

For a supplier to bill Part B on your behalf, it must hold active Medicare billing privileges. If those privileges are revoked, the supplier cannot legally submit a claim to Medicare, and you cannot be reimbursed even if you pay out of pocket and try to file yourself.

What to Do If Your Supplier Is Banned

The first step is verification. Go to Medicare.gov and use the Care Compare or Supplier Directory tool to search for your current supplier by name or zip code. An authorized supplier will show an active enrollment status. If your supplier does not appear, or appears with a revoked status, treat that as a red flag requiring immediate action.

Contact your prescribing physician right away. Your doctor's office can issue a new prescription and refer you to an authorized supplier. Do not simply switch suppliers on your own without a new order — Medicare requires a valid prescription tied to a specific enrolled supplier for most DME categories.

If you are already receiving ongoing supplies, such as monthly diabetic testing strips or rental equipment like a CPAP machine, a gap in supplier authorization can interrupt automatic shipments. Call 1-800-MEDICARE (1-800-633-4227) to report the disruption and ask for guidance on transitional coverage options.

The Fraud Connection You Should Understand

Many of the banned suppliers were not simply incompetent — they were actively fraudulent. Common schemes include billing Medicare for power wheelchairs prescribed to patients who can walk, submitting claims for deceased beneficiaries, and using stolen Medicare numbers to order equipment that is then resold. These schemes inflate Part B costs for everyone and contribute to premium increases over time.

You can protect yourself by reviewing your Medicare Summary Notice, which arrives quarterly and lists every claim billed in your name. If you see equipment you never received, a supplier you never contacted, or services on dates when you were not treated, report it immediately. The HHS Office of Inspector General operates a fraud hotline at 1-800-HHS-TIPS and accepts online reports at oig.hhs.gov.

Enrollment Penalties Are a Separate but Related Risk

Some beneficiaries, frustrated by supplier disruptions or billing confusion, consider dropping Part B temporarily. This is a serious mistake. If you go without Part B coverage for 12 or more consecutive months outside of a qualifying Special Enrollment Period, you will owe a permanent late enrollment penalty equal to 10 percent of the standard Part B premium for each full year you lacked coverage. That penalty stays with you for life.

The standard Part B premium in 2024 is $174.70 per month. A two-year gap would add roughly $35 per month to your premium permanently. Supplier problems are solvable. Enrollment penalties are not.

Protecting Yourself Going Forward

Verify supplier status annually, not just when a problem arises. Medicare enrollment status can change, and a supplier that was legitimate last year may have had its privileges suspended since then. When your doctor writes a new DME prescription, ask the office staff to confirm the supplier is currently enrolled before you place an order.

If you have a Medicare Advantage plan rather than Original Medicare, your plan has its own network of approved DME suppliers. The same principle applies: use only in-network, plan-approved suppliers to avoid unexpected costs.

The broader enforcement trend is not going away. CMS has signaled continued aggressive action against fraudulent suppliers, which is good news for the program's long-term solvency but requires beneficiaries to stay engaged with who is billing on their behalf.

Frequently Asked Questions

How do I find out if my medical supply company is still authorized by Medicare?

Visit Medicare.gov and use the Supplier Directory tool to search by company name or zip code. An authorized supplier will show active enrollment status. You can also call 1-800-MEDICARE (1-800-633-4227) and a representative can verify supplier status for you. CMS updates its enrollment records regularly, so check before placing any new equipment order.

Will Medicare pay my claim if I unknowingly used a banned supplier?

Generally, no. Once a supplier's billing privileges are revoked by CMS, Medicare will not pay claims that supplier submits, regardless of whether you knew about the revocation. You also cannot self-file for reimbursement in most cases. Contact 1-800-MEDICARE immediately to report the situation and ask whether any exception or transitional coverage applies to your specific equipment.

What is the 20 percent coinsurance rule for durable medical equipment under Part B?

Under Original Medicare Part B, after you meet the annual deductible — $240 in 2024 — Medicare pays 80 percent of the approved amount for covered durable medical equipment and you pay the remaining 20 percent. There is no annual out-of-pocket cap under Original Medicare, so costs can accumulate significantly for expensive or long-term equipment needs.

Can I report a fraudulent medical supply company to Medicare?

Yes. Report suspected DME fraud to the HHS Office of Inspector General at 1-800-HHS-TIPS (1-800-447-8477) or online at oig.hhs.gov. You should also review your quarterly Medicare Summary Notice for any claims you do not recognize. CMS and the OIG use beneficiary reports as leads in fraud investigations that have recovered billions of dollars from bad actors.

What happens to my ongoing equipment rentals if my supplier is banned mid-rental?

If your supplier loses Medicare billing privileges during an active rental period — for example, a CPAP or oxygen concentrator — your shipments or service may stop without warning. Contact your prescribing physician immediately for a new prescription and referral to an authorized supplier. Call 1-800-MEDICARE to report the disruption; CMS may have transitional guidance depending on the equipment category.

Does a Medicare Advantage plan protect me differently from supplier bans than Original Medicare?

Medicare Advantage plans maintain their own networks of approved DME suppliers, separate from the Original Medicare supplier enrollment system. If your Advantage plan's contracted supplier loses its plan authorization, the plan is required to help you transition to another in-network supplier. Contact your plan directly using the member services number on your insurance card to get a replacement supplier referral within your network.
