Medicare Part B and DME Coverage
Medicare Part B covers durable medical equipment (DME) when it’s medically necessary and prescribed by an enrolled physician. But navigating the coverage rules can trip up even experienced providers.
Here’s what you need to know to keep claims clean and patients equipped.
The Five Requirements for DME Coverage
For an item to qualify as DME under Medicare, it must meet all five criteria:
- Durable — Can withstand repeated use over an extended period
- Medical purpose — Primarily and customarily used for a medical purpose
- Not useful without illness — Generally not useful to a person who isn’t sick or injured
- Appropriate for home use — Suitable for use in the patient’s home
- Prescribed by a physician — Ordered by an enrolled Medicare provider
Items like hospital beds, wheelchairs, CPAP machines, and oxygen equipment typically qualify. Items considered “convenience” or “comfort” generally don’t.
Documentation That Prevents Denials
The number one reason for DME claim denials? Insufficient documentation. Medicare requires:
- Detailed written order (DWO) — Must include the beneficiary’s name, item description, prescribing physician’s NPI, and signature
- Certificate of Medical Necessity (CMN) — Required for certain items like oxygen equipment, hospital beds, and support surfaces
- Face-to-face encounter — The prescribing physician must have seen the patient within 6 months prior to the order
- Progress notes — Must support the medical necessity of the item
Pro Tip
Get the documentation right the first time. Retroactive corrections raise red flags during audits and can delay reimbursement by weeks.
Common Coverage Categories
| Category | Examples | CMN Required? |
|---|---|---|
| Mobility | Wheelchairs, walkers, rollators | No (most) |
| Respiratory | CPAP, oxygen concentrators, nebulizers | Yes |
| Hospital beds | Manual and electric | Yes |
| Patient monitoring | Blood pressure monitors, pulse oximeters | No |
| Support surfaces | Pressure-reducing mattresses | Yes |
The Competitive Bidding Program
Medicare uses a competitive bidding program (CBP) for certain DME items in specific areas. This means only contracted suppliers can provide these items to Medicare beneficiaries in those regions.
What this means for providers: Always verify that your DME supplier holds the appropriate Medicare contracts for your service area. Working with a non-contracted supplier means your patients may face higher out-of-pocket costs — or no coverage at all.
