Do you need a prescription for an oxygen concentrator? Yes — here's how it works
Part of the series: The Complete Oxygen Concentrator GuideConcentrators are Class II medical devices, so the prescription isn't our policy — it's federal law. What verification actually looks like when you order.
Every oxygen concentrator — portable or stationary, new or refurbished — is a prescription device under FDA regulation, so a valid prescription is required before one ships regardless of how you pay. Retailers that make this feel optional are the ones to be wary of: the prescription requirement exists because oxygen dosing is a clinical decision, and too much oxygen carries its own risks, particularly for some COPD patients.
The prescription itself is usually simpler than people expect: a flow rate (or pulse setting range), a duration pattern — continuous, nocturnal, with exertion — and the prescriber's signature. If you've had a recent pulmonology visit or an oxygen titration, it likely already exists in your chart and just needs to be sent.
At CIRRUS, verification happens at checkout: upload the prescription or give us your prescriber's details and we confirm it directly. A concierge specialist checks that the machine you've ordered actually satisfies what's written — a 4 LPM continuous prescription quietly doesn't fit most pulse-dose portables, and catching that before shipment is the entire point of the step. Once verified, standard delivery is 48 hours.
What doesn't need a prescription: pulse oximeters, carrying cases, batteries, cannulas, and most accessories. So if you're preparing for a purchase, an oximeter to understand your resting and exertion saturation is something you can order today while the prescription conversation happens with your doctor.
