Does Medicare Cover Durable Medical Equipment? A Complete Billing Guide

**Reading time:** 8 minutes | **Medical review:** [Date]

If you're a Medicare beneficiary shopping for medical equipment, you've probably asked: *"Will Medicare pay for this?"* The answer isn't always straightforward. While Medicare Part B does cover many types of durable medical equipment (DME), navigating the approval process, documentation requirements, and supplier networks can feel overwhelming.

This guide breaks down exactly what Medicare covers, how the billing process works, and what you need to know before making a purchase.

What Is Durable Medical Equipment (DME)?

Medicare defines DME as equipment that meets all of these criteria:

- **Durable** — Can withstand repeated use (expected lifetime of 3+ years)
- **Medically necessary** — Required for medical reasons, not convenience
- **Used in the home** — Primarily for use in your residence
- **Not useful to someone without an illness or injury**

**Common DME categories covered by Medicare:**
- Mobility aids (walkers, wheelchairs, power scooters)
- Respiratory equipment (oxygen, nebulizers, CPAP machines)
- Orthopedic supports (back braces, knee braces, compression garments)
- Diabetic supplies (glucose monitors, test strips)
- Patient lifts and bathroom safety equipment
- TENS units for chronic pain

## How Medicare DME Billing Works

### Step 1: Get a Prescription
Before Medicare will cover any DME, you need:
- A written order from your Medicare-enrolled physician
- Specific diagnosis codes (ICD-10)
- Documentation showing medical necessity

### Step 2: Choose a Medicare-Approved Supplier
Medicare requires you to purchase from suppliers who:
- Are enrolled in Medicare
- Have a Medicare supplier number
- Accept "assignment" (agree to Medicare's approved amount)

**Important:** If you buy from a non-approved supplier, Medicare won't pay — even if the item is covered.

### Step 3: Understand Your Costs

**Original Medicare (Part B):**
- You pay **20%** of the Medicare-approved amount
- Medicare pays **80%**
- You must meet your Part B deductible first ($240 in 2024)

**Example:** A $200 back brace
- Medicare-approved amount: $180
- You pay: $36 (20%)
- Medicare pays: $144 (80%)

**Medicare Advantage (Part C):**
- Coverage varies by plan
- May have lower copays or additional covered items
- Check your plan's DME benefits

## The Competitive Bidding Program

Medicare uses a Competitive Bidding Program for certain DME in specific areas. This affects:
- Oxygen equipment
- Wheelchairs and scooters
- CPAP devices
- Hospital beds

**What this means for you:**
- You must use a "contract supplier" in your area
- Prices are pre-negotiated (often lower)
- Find contract suppliers at Medicare.gov/supplier

---

## Documentation Requirements

To ensure smooth reimbursement, your doctor must document:

1. **Face-to-face examination** — Must occur within 6 months of the DME order
2. **Specific diagnosis** — Can't just say "knee pain"; need specific condition
3. **Medical necessity justification** — Why this equipment is required
4. **Expected duration of need** — Temporary vs. long-term use

**Red flag:** If a supplier offers to "handle all the paperwork" without a proper doctor's evaluation, that's Medicare fraud. Run away.

---

## Rent vs. Buy: What Medicare Decides

Medicare determines whether you rent or purchase DME based on the item:

| Equipment Type | Medicare's Approach |
|----------------|---------------------|
| Oxygen equipment | 36-month rental, then you own it |
| Power wheelchairs | Purchase (if approved) |
| Hospital beds | 13-month rental, then ownership |
| CPAP machines | 13-month rental if criteria met |

After the rental period, equipment becomes your property.

## Common Billing Mistakes to Avoid

### ❌ Buying First, Asking Later
Many patients purchase equipment thinking "I'll get reimbursed." If you don't follow Medicare's process, you won't be. Always get pre-approval when possible.

### ❌ Wrong Supplier
Only Medicare-enrolled suppliers can bill Medicare directly. Check enrollment status at Medicare.gov/supplier before purchasing.

### ❌ Missing Prescription Details
Your prescription must include:
- Doctor's signature and date
- Your diagnosis
- Specific equipment description
- Length of need

### ❌ Not Understanding "Assignment"
"Accepting assignment" means the supplier agrees to Medicare's price. If they don't accept assignment, they can charge you up to 15% more than the Medicare-approved amount.

## How to Check If Your Equipment Is Covered

### Before You Buy:
1. Ask your doctor: *"Is this Medicare-covered DME?"*
2. Call Medicare: **1-800-MEDICARE** (1-800-633-4227)
3. Check online: Medicare.gov/coverage/durable-medical-equipment
4. Verify supplier enrollment: Medicare.gov/supplier

### Questions to Ask Your Supplier:
- *"Are you enrolled in Medicare?"*
- *"Do you accept assignment for this item?"*
- *"What's my out-of-pocket cost after Medicare pays?"*
- *"Will you bill Medicare directly, or do I need to submit claims?"*

## When Medicare Says "No": Your Options

If Medicare denies coverage, you have rights:

1. **Appeal the decision** — You have 120 days to file an appeal
2. **Request a redetermination** — Ask Medicare to review the decision
3. **Pay out-of-pocket** — Some patients choose to purchase anyway
4. **Look into Medicare Advantage** — Some plans offer broader DME coverage
5. **Check Medicaid** — If you have dual eligibility, Medicaid may cover gaps

## Medicare vs. Medicaid: What's the Difference?

| Feature | Medicare | Medicaid |
|---------|----------|----------|
| **Who qualifies** | 65+ or disabled | Low-income (varies by state) |
| **DME coverage** | Part B (80/20 split) | Varies by state, often broader |
| **Supplier requirements** | Must be Medicare-enrolled | Must be Medicaid-enrolled |
| **Copays** | 20% after deductible | Usually $0 or minimal |

**Dual eligible?** If you have both Medicare and Medicaid, Medicaid often covers your 20% Medicare coinsurance.

## FAQ: Medicare DME Billing

**Q: Can I buy DME online and still get Medicare coverage?**
A: Yes, if the online supplier is Medicare-enrolled and accepts assignment. Always verify before purchasing.

**Q: Does Medicare cover compression stockings?**
A: Sometimes. Compression stockings over 20 mmHg may be covered with a prescription for venous insufficiency or post-surgical recovery. Graduated compression for varicose veins is typically covered; athletic compression is not.

**Q: How long does Medicare approval take?**
A: Simple items (walkers, basic braces): often immediate at point of sale. Complex items (power wheelchairs, oxygen): 5-10 business days for prior authorization.

**Q: Can I upgrade my equipment and pay the difference?**
A: Yes, but Medicare only pays their approved amount for the base model. You pay 20% of the base cost PLUS 100% of the upgrade cost.

**Q: What if I move to a different state?**
A: Your DME coverage follows you, but supplier networks vary. You may need to switch to a new Medicare-enrolled supplier in your new area.

**Q: Does Medicare cover TENS units?**
A: Yes, for chronic pain management, but you typically need:
- Prescription from pain management doctor or neurologist
- Documented chronic pain (3+ months)
- Failed trial of other treatments
- Trial period showing TENS effectiveness

3. **Understand your costs** — Budget for 20% coinsurance plus any deductible
4. **Ask about "assignment"** — This affects your out-of-pocket costs
