How to apply for medical equipment through Medicare or Medicaid: a guide

Applying for medical equipment through Medicare or Medicaid can feel overwhelming. Which program pays for what? What paperwork do you need? How do you choose a supplier? This guide breaks down the process into clear steps so you can get the equipment you need with fewer surprises.

Start by knowing the basic difference between the two systems. Medicare is a federal program mainly for people 65 and older and some younger people with disabilities. Medicaid is a joint federal-state program for people with low income and limited resources; rules and covered items vary by state. Both programs may cover durable medical equipment (often called DME), but the rules, prior authorization processes, and suppliers can differ. Read on for eligibility specifics, documentation tips, how to work with prescribers and suppliers, and what to do if a claim is denied.

Durable medical equipment (DME) refers to medical items ordered by a doctor for use in the home. Common examples include wheelchairs, walkers, hospital beds, oxygen equipment, continuous positive airway pressure (CPAP) machines, and prosthetic devices used for mobility. Medicare Part B typically covers DME that is medically necessary for use at home, while Medicaid coverage varies by state and may cover additional items or have different limits.

Medicare Part B covers DME if it meets these basic criteria: the item is durable (long-lasting), used for a medical reason, not generally useful without an illness or injury, used in the home, and ordered by a doctor. For Medicaid, each state publishes its DME covered services and criteria. Some states require prior authorization for certain expensive items or rental arrangements. If you have both Medicare and Medicaid (dual-eligible), Medicare is usually billed first for services covered by both programs, and Medicaid may cover remaining cost-sharing or items Medicare does not cover.

Before applying, gather basic eligibility documentation. For Medicare, you need your Medicare ID and proof of enrollment in Part B if applicable. For Medicaid, have your state Medicaid ID and proof of income or other eligibility documents as required by your state. If you are dual-eligible, have both identifiers available so providers can bill correctly.

Clinical documentation is critical. Most DME requires a written order or prescription from a treating clinician that includes the patient’s diagnosis, the specific equipment requested, how the equipment will be used, and the expected duration of need. Additional supporting documents often help, such as physician notes showing functional limitations, results from tests (like pulmonary function tests for oxygen needs or sleep study results for CPAP), and therapy notes if mobility aids are involved. Keep copies of all documents and a dated log of conversations with providers and suppliers.

Talk with the clinician who manages the condition. Be specific about what you need and why. A generic prescription like “assistive device” is often not enough. The order should specify the exact item (for example, “standard manual wheelchair” or “hospital bed with side rails”), expected frequency of use, and the medical rationale. Ask the clinician to include objective measures when possible—mobility tests, oxygen saturation readings, or sleep study results make claims clearer.

Choosing a supplier matters. Medicare requires DME suppliers to be enrolled and accredited to bill Medicare. For Medicaid, state rules determine approved suppliers. Ask suppliers about their billing practices, whether they accept assignment (which affects your out-of-pocket costs), delivery and setup policies, rental versus purchase options, and maintenance or warranty coverage. Confirm that the supplier will file claims for you. If the supplier suggests you pay up front and seek reimbursement, weigh that option carefully and get written terms.

Once you have a valid order and a supplier, the supplier usually handles the claim submission. For Medicare Part B, suppliers must submit a claim to Medicare for the DME. Medicare typically covers 80% of the Medicare-approved amount after the Part B deductible is met; the remaining 20% can be billed to a secondary insurer or Medicaid if you are eligible, or you pay it out of pocket. Medicaid rules about coinsurance and copays vary by state; some states waive cost sharing for certain populations.

Expect potential steps like prior authorization or advance beneficiary notice. Some items require prior authorization—a formal approval before the supplier fills the order. If a supplier believes Medicare will not cover the item, they must provide an Advance Beneficiary Notice of Noncoverage (ABN) to let you know you may be responsible for payment. Keep clear records of claim numbers, dates of submission, and any correspondence. If a claim is denied, review the denial reason carefully and ask the supplier or billing office for clarification before assuming the decision is final.

Receiving equipment is one step; maintaining it is another. Ask about service, repair, and replacement policies. Many suppliers include a warranty or offer repair services; Medicaid programs sometimes provide for repairs or replacements under medical necessity. Document any malfunctions and contact the supplier promptly. For oxygen and ventilator supplies, vendors often handle deliveries and routine checks. For mobility devices, periodic reassessment by a clinician may be needed to update medical necessity.

If coverage is denied, you have appeal rights. Medicare offers a multi-level appeal process starting with a redetermination by the contractor and potentially moving to an independent review. Medicaid appeals vary by state but generally allow you to request a fair hearing. When appealing, submit supporting clinical evidence, letters from treating clinicians, dated treatment notes, and any relevant tests. Consider working with a patient advocate, case manager, or social worker who can help organize documentation and represent your case. Also explore alternatives like non-profit loaner programs, community resources, or state assistive technology programs that can provide temporary or low-cost solutions while appeals are pending.

Looking ahead, staying proactive reduces stress. Keep an organized folder of all orders, receipts, billing statements, and communications. Schedule follow-ups with clinicians to reassess needs. Understand your coverage limits and how rental versus purchase affects future care. With good documentation, a reliable supplier, and timely communication, you can improve the chances of obtaining and keeping the equipment that supports daily life.
