Medicare DME Coverage After Hospital Discharge in California

Your parent is being discharged from a California hospital and needs a hospital bed at home, a wheelchair for mobility, or an oxygen concentrator. Medicare covers this equipment — called Durable Medical Equipment — but the coverage comes with rules about prescriptions, supplier selection, and rental vs purchase that the hospital's discharge planner may not explain in detail. Getting it wrong means your parent arrives home to an empty bedroom where a hospital bed should be.

What Medicare Part B Covers

Medicare Part B covers DME that is medically necessary, prescribed by a physician, appropriate for use in the home, and durable (expected to last at least three years). Common items covered after a hospital discharge include hospital beds, wheelchairs, walkers, oxygen equipment, patient lifts, and nebulizers. Coverage depends on the item's medical-necessity and documentation requirements; shower chairs and other bathroom aids are not automatically covered.

Under Original Medicare, Medicare pays 80% of the approved amount after the annual Part B deductible. The patient or their supplemental insurance pays the remaining 20% coinsurance.

Most DME is rented rather than purchased. For items in the capped-rental category, Medicare generally pays rental for 13 months, after which ownership transfers to the patient at no additional cost. Oxygen equipment follows different rental rules. During the rental period, the supplier is responsible for maintenance and repairs.

The Prescription Requirement

Medically necessary DME must be ordered by the treating clinician, with the documentation required for the item. Before discharge, confirm that the order and supporting medical-necessity documentation have been sent to the supplier; do not rely on a verbal request alone.

Before your parent is discharged, confirm with the attending physician that all necessary DME orders have been written and transmitted to a supplier. The most common discharge delay is not the medical clearance — it is the DME order sitting in a queue while the equipment company waits for a physician signature.

If your parent's physician has not yet signed the required order on the day of discharge, ask the discharge planner to escalate before the equipment is delivered or your parent leaves.

Choosing a DME Supplier

Supplier rules depend on the payer, item, and location. Under Original Medicare, confirm that the supplier is Medicare-enrolled and serves your area; Medicare Advantage plans may require an in-network supplier or prior authorization.

The hospital's discharge planner may have a preferred supplier. Ask for the available supplier options and confirm the applicable payer rules and delivery timeline directly with the supplier.

Before committing to a supplier, ask about delivery timing. If your parent is being discharged Thursday and the supplier cannot deliver the hospital bed until Monday, you have a problem. Negotiate the delivery date before discharge, not after.

Common Timing Failures

The most frequent DME-related discharge failure is the gap between when your parent arrives home and when the equipment is delivered. A patient discharged to a home without a hospital bed may sleep in a recliner and fall trying to get up. A patient without a wheelchair may attempt to walk to the bathroom and fall.

To prevent this, coordinate DME delivery for the day of discharge or the day before. Some suppliers offer same-day or next-day delivery for urgent post-hospital orders — but only if the physician's order is in their system. Start the process at least 48 hours before the expected discharge date.

If the equipment absolutely cannot arrive on discharge day, consider whether a short delay in discharge is safer than sending your parent home without it. Under California law, the hospital cannot force a discharge to an unsafe environment, and the absence of medically necessary equipment in the home is a legitimate safety concern.

When Medicare Denies DME Coverage

If Medicare denies coverage for a specific item, you will receive a Medicare Summary Notice explaining the denial reason. Common denial reasons include insufficient documentation of medical necessity, a missing or incomplete physician order, or the item being classified as a convenience rather than a medical need.

You can appeal a DME denial through the standard Medicare appeals process. The first level is a redetermination request to the DME Medicare Administrative Contractor. If that fails, you escalate to a reconsideration by a Qualified Independent Contractor. Most denials based on documentation errors are resolved at the first appeal level once the physician provides a more detailed letter of medical necessity.

The California Hospital Discharge Guide includes a DME coordination checklist designed to be started 48 hours before discharge, covering physician orders, supplier selection, delivery scheduling, and insurance verification.
