medicare durable medical equipment denial notices usually arrive after the equipment is already in the house. The wheelchair is by the door. The hospital bed is set up in the living room. The oxygen concentrator hums all night. Then a letter says Medicare will not pay for it. Sometimes the supplier calls first. Sometimes the word “Denied” simply appears on a quarterly statement.

That letter is not the last word. It is the first decision in a five-level appeal system with named forms and fixed deadlines. A medicare durable medical equipment denial can be challenged by the person on Medicare, or by someone they appoint. This guide names the notices, the form numbers, the decision-makers and the free phone lines. It describes the process. It does not predict how any case will end.
What “medicare durable medical equipment denial” Actually Means
Durable medical equipment is gear you use at home over time. Manual and power wheelchairs. Hospital beds. Oxygen concentrators and tanks. Walkers, CPAP machines, nebulizers, commodes, lifts.
Under Original Medicare, DME sits in Part B. The claim goes to a DME Medicare Administrative Contractor, called a DME MAC. There are four of them, split by where the patient lives. The DME MAC issues the first decision.
A medicare durable medical equipment denial usually rests on one of a few reasons. The documentation did not show medical necessity. The face-to-face visit or the written order was missing or late. The supplier was not enrolled or not accredited. Or Medicare treats the item as not covered at all.
The reason code matters more than the denial itself. Read it before writing anything. The full appeals ladder is described at Medicare.gov’s Original Medicare appeals page.
The Deadline You Cannot Miss
The clock starts with the notice, not with the phone call from the supplier. In Original Medicare, the notice is the Medicare Summary Notice (MSN). It is mailed every three months and is also posted in the online Medicare account.
You have 120 days from the date you receive the MSN to file the first appeal, called a redetermination. Medicare presumes you received the notice five days after the date printed on it. If you signed an Advance Beneficiary Notice of Noncoverage (Form CMS-R-131) before pickup, keep that copy; it explains why the supplier expected a denial.
In a Medicare Advantage plan the notice is different. The plan issues an organization determination, and the deadline to appeal is 65 days. Confirm your plan’s exact wording in its Evidence of Coverage or at Medicare.gov’s health plan appeals page.
| Level | What you file | Who decides | Your deadline | Their target |
|---|---|---|---|---|
| 1. Redetermination | Form CMS-20027 | DME MAC | 120 days from MSN receipt | 60 days |
| 2. Reconsideration | Form CMS-20033 | Qualified Independent Contractor (QIC) | 180 days from the redetermination notice | 60 days |
| 3. ALJ hearing | Form OMHA-100 | Administrative Law Judge, Office of Medicare Hearings and Appeals | 60 days from the reconsideration notice | 90 days (often longer) |
| 4. Council review | Form DAB-101 | Medicare Appeals Council, Departmental Appeals Board | 60 days from the ALJ decision | 90 days (often longer) |
| 5. Federal court | Civil complaint | U.S. District Court judge | 60 days from the Council decision | No set time |
Level 3 has a dollar floor. For 2026 the amount in controversy is $200, and for federal court review it is $1,960, per the CMS annual adjustment notice. Claims can be combined to reach the threshold. See CMS on the third level of appeal.
How to Start a Medicare Durable Medical Equipment Denial
Step one: get the notice in front of you. Find the item, the date of service, the claim number and the denial reason on the MSN.
Step two: choose your filing method. You can follow the MSN instructions and mail the signed notice itself, or use Form CMS-20027, the Medicare Redetermination Request Form. Many DME MACs also accept redeterminations through their secure provider and beneficiary portals.
Step three: address it correctly. The appeal goes to the DME MAC listed on the MSN, not to your doctor and not to the supplier. The mailing address is printed on the notice. Sending a medicare durable medical equipment denial appeal to the wrong contractor wastes weeks.
Step four: send it trackable and keep a copy of everything. Certified mail or a portal receipt gives you a filing date you can prove.
Step five: call for help while you build the file. 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) is free and open 24 hours. Your State Health Insurance Assistance Program (SHIP) gives free one-on-one counseling; find yours at shiphelp.org or by calling 1-877-839-2675.
The Medicare Rights Center runs a free national helpline at 1-800-333-4114 and publishes step-by-step packets at Medicare Interactive. A note on the QIO: Beneficiary and Family Centered Care QIOs handle hospital discharge appeals and quality-of-care complaints, not DME claim denials. Your state’s QIO number is on the MSN and available from 1-800-MEDICARE.
What to Put in the File
Paper decides these cases. A medicare durable medical equipment denial is reviewed on the record, so the record has to say what the reviewer needs to see.
Gather the standard written order or prescription, the chart notes from the face-to-face visit, and the delivery ticket from the supplier. Add hospital or rehab discharge summaries. For oxygen, include the qualifying blood gas or oximetry test results and the date they were taken.
The document that moves cases most often is a fresh letter from the treating clinician. Ask for specifics, not adjectives. What is the diagnosis. What has already been tried and failed. What happens in the home without the equipment.
Have the letter tie the need to the coverage criteria in the relevant Local Coverage Determination. Ask the supplier for the LCD number tied to the billing code.

If the First Level Says No
The DME MAC’s answer arrives as a Medicare Redetermination Notice (MRN). If it upholds the medicare durable medical equipment denial, level two is a reconsideration by a Qualified Independent Contractor, an outside reviewer.
File Form CMS-20033 within 180 days of receiving the MRN. Details are at the CMS second-level appeal page. Add any new evidence here. At level three and beyond, submitting new evidence generally requires showing good cause.
Level three is a hearing before an Administrative Law Judge at OMHA, usually by phone or video. Level four is the Medicare Appeals Council. The Center for Medicare Advocacy publishes free self-help material on every level.
Mistakes That Sink a Medicare Durable Medical Equipment Denial
Waiting for the supplier to handle it. Suppliers sometimes appeal and sometimes do not. The beneficiary’s deadline runs either way.
Appealing with a phone call only. Redeterminations must be in writing. Notes from a call are not a filed appeal.
Sending the same file twice. If nothing new is added, the reviewer sees the same gap that caused the medicare durable medical equipment denial.
Missing the signature or the representative form. If a family member files, appoint them using Form CMS-1696, Appointment of Representative, signed by both people.
Assuming a late filing is hopeless. There is a good cause process for late appeals, but it must be requested and explained. Ask 1-800-MEDICARE or your SHIP how to raise it.
Frequently Asked Questions
Does the equipment get taken away while the appeal runs?
That depends on your rental or purchase agreement with the supplier, not on Medicare’s appeal rules. Ask the supplier in writing what happens during the appeal. Get the answer before you return anything.
Who can file for a parent who cannot manage it?
A family member, friend, attorney or the supplier can act as your representative. Use Form CMS-1696 unless a court order or state law already gives that authority. Send it with the appeal, not after.
Is the process different in a Medicare Advantage plan?
Yes. You appeal to the plan first, generally within 65 days of the organization determination. Standard decisions are typically due in 30 days and expedited ones in 72 hours. Confirm the exact timeframes with your plan and your SHIP.
Do I need a lawyer?
Nothing in the rules requires one at any level. Free counseling is available from SHIP, the Medicare Rights Center and 1-800-MEDICARE. This article is general information about the process, not legal advice about your situation.
