A Portable Oxygen Concentrator (POC) is a medical device that filters and concentrates oxygen from the surrounding air, providing a continuous supply to the user. Unlike heavy oxygen tanks, the POC is lightweight, battery-operated, and designed to increase mobility for individuals requiring supplemental oxygen therapy. Acquiring one involves navigating a regulated process that begins with medical evaluation and continues through supplier selection and financial planning. This guide details the necessary steps and resources to successfully obtain a POC.
Obtaining the Medical Authorization
A portable oxygen concentrator is classified as a regulated medical device, meaning suppliers cannot legally provide one without a valid prescription from a licensed physician. The first step is a comprehensive medical consultation to establish a diagnosis and confirm the medical necessity for oxygen therapy. This authorization is based on physiological testing, which typically includes a pulse oximetry test to measure oxygen saturation in the blood, and often an arterial blood gas study.
These tests must confirm that your blood oxygen level falls below certain thresholds, usually an oxygen saturation (SpO2) of 88% or less. The physician’s prescription specifies the required oxygen flow rate in liters per minute (LPM) and the usage schedule. This documentation dictates the type and setting of the device you will need, given that many POCs use a pulse dose delivery that is not a direct equivalent to a continuous LPM setting.
Where to Find Portable Oxygen Concentrators
The primary source for obtaining a portable oxygen concentrator is a Durable Medical Equipment (DME) supplier, specializing in medical devices for home use. These suppliers work directly with prescribers to match the flow rate and usage requirements detailed in the medical authorization to a suitable device model. Many DME providers have established relationships with insurance carriers, including Medicare, which streamlines the coverage and billing process.
A second option is to purchase a device directly from a specialty online retailer or a manufacturer’s authorized distributor. These sources often provide a wider selection of the newest models, though they still require a physician’s prescription before shipping the unit. When considering a direct purchase, understand the difference between continuous flow models, which deliver a constant stream of oxygen, and pulse dose technology, which delivers oxygen only upon inhalation to conserve battery life. Renting from a DME supplier or a dedicated rental agency is often preferred for short-term needs, such as a vacation or a temporary medical condition.
Understanding Costs and Coverage
Portable oxygen concentrators represent a significant financial investment, with purchase prices for new models often ranging from $2,500 to over $4,000. For individuals with Medicare, the device is covered as Durable Medical Equipment (DME) under Part B, but the coverage is for rental, not purchase. Medicare generally covers 80% of the approved rental cost, but the patient remains responsible for the annual Part B deductible and a 20% coinsurance payment.
Under Medicare rules, you rent the equipment from an approved supplier for a period of 36 months. After this period, the supplier must continue providing the equipment and its maintenance for an additional 24 months, provided the oxygen therapy remains medically necessary. If you have private health insurance, contact your carrier directly to determine your specific benefits, including required prior authorization, deductibles, and whether the supplier is in-network. Policy details must be verified before committing to a device, as some private plans may offer different terms, such as a partial allowance toward a purchase.
Finalizing Your Acquisition
Once the medical authorization is secured and financial arrangements are clear, the final steps focus on the device’s practical features and the supplier’s support. Before finalizing the transaction, confirm the device has been approved by the Federal Aviation Administration (FAA) if you anticipate air travel. FAA-approved POCs must bear a label confirming conformance to be allowed on commercial aircraft.
Review the warranty offered by the manufacturer or supplier, as this covers potential defects and repairs over a specified period. Ensure the supplier provides 24/7 technical support, as oxygen equipment requires prompt attention if operational issues arise. Finally, understand the device’s maintenance schedule, including filter cleaning or replacement, and the expected lifespan of the rechargeable batteries.
