Does Medicare cover portable oxygen concentrators? The honest answer

Medicare Part B does cover oxygen equipment for home use, and it's worth being precise about the mechanics: after the Part B deductible you pay 20% of the Medicare-approved amount, and the equipment comes as a rental from a Medicare-enrolled supplier that runs 36 months. You don't own the machine at the end — it's an equipment service arrangement, with tanks, tubing, and supplies bundled in.

The part that surprises people: the supplier — not you — selects the specific equipment, under your doctor's order. Medicare's own coverage language requires the supplier to provide equipment that fits your needs, including mobility, but it doesn't entitle you to a particular model, and the type of equipment can't change month to month unless your doctor orders a change. If what you specifically want is a lightweight portable concentrator for travel, that decision sits with the supplier's inventory and economics, not your preference.

Eligibility is also narrower than most assume: your provider has to document that you aren't getting enough oxygen, that oxygen therapy is expected to help, and that your arterial blood gas falls in a qualifying range. That's the clinical gate for the rental program — and it's the right gate for Medicare's purpose, which is treating hypoxemia, not optimizing which machine you'd rather carry through an airport.

Buying outright is the other path, and it's the one CIRRUS is built for: you pick the exact model, you own it, and there's no 36-month arrangement or supplier relationship to manage. We don't bill Medicare, Medicaid, or insurance at all — by design — so the price on the page is simply the price. Which path is right depends on your finances and how much the specific machine matters to you; the honest version of this comparison is that Medicare's program is a strong deal for standard home setups and a poor fit for people who want a specific portable unit.
