Renting oxygen tanks and related delivery systems for supplemental oxygen therapy is standard practice. This equipment is formally classified as Durable Medical Equipment (DME) and is heavily regulated. Renting offers a temporary or long-term solution for individuals requiring oxygen therapy at home, avoiding the high upfront cost of purchasing specialized medical devices.
Understanding Medical Necessity and Authorization
Securing oxygen equipment rental requires establishing medical necessity via a doctor’s order. This order typically takes the form of a Certificate of Medical Necessity (CMN), a standardized document submitted to the supplier and insurance provider. The CMN confirms the patient has a qualifying respiratory condition, such as Chronic Obstructive Pulmonary Disease (COPD) or severe sleep apnea, that warrants supplemental oxygen use.
The prescription is highly specific, detailing the required oxygen flow rate in liters per minute (LPM) and the duration of use (e.g., continuous or only while sleeping). This information determines the type and capacity of the equipment the supplier is authorized to provide. Without this formal authorization, suppliers cannot legally dispense or rent medical oxygen equipment.
Comparing Rental Equipment: Tanks Versus Concentrators
The rental market offers two distinct types of equipment: compressed gas cylinders (tanks) and oxygen concentrators. Tanks store a finite amount of 100% pure oxygen under high pressure in a metal container. They are typically smaller and more portable, suitable for short-term use, such as trips outside the home or as a backup during power outages. However, tanks require frequent exchanges or refills because the supply is limited, creating an ongoing logistical need.
Oxygen concentrators are the standard for long-term rental, generating oxygen on demand from the surrounding air. These devices draw in ambient air, filter out nitrogen, and deliver concentrated oxygen at 90% to 95% purity. Concentrators are available in stationary home models and portable battery-operated units, offering an unlimited supply as long as a power source is available. For patients needing continuous, high-flow oxygen, a stationary concentrator provides a reliable solution that eliminates the need for frequent gas deliveries.
Navigating Insurance Coverage and Costs
Oxygen equipment rental is primarily managed through the Durable Medical Equipment (DME) benefit of health insurance. For Medicare beneficiaries, oxygen equipment follows specific rules, establishing a five-year rental cycle. Medicare pays the supplier a monthly rental fee for the first 36 months, covering the equipment, supplies, and maintenance.
The patient is responsible for a 20% coinsurance of the Medicare-approved amount after meeting the Part B deductible. After the initial 36-month period, the supplier must continue providing the equipment and necessary contents (e.g., oxygen refills for tanks) for an additional 24 months, totaling five years. During this final 24-month period, the patient continues to pay the 20% coinsurance for necessary contents or maintenance visits.
Private insurance and Medicaid plans generally follow a similar DME rental model, though coverage details, co-pays, and deductibles can vary significantly by state and plan. Some private plans adhere to the 13-month capped rental rule, where equipment ownership transfers after 13 months of payments, while others follow the 36-month oxygen rental cycle. For individuals without insurance or travelers needing a portable unit, out-of-pocket costs involve daily or weekly rental rates negotiated directly with the supplier.
The Rental Process and Delivery Logistics
Once medical necessity is authorized and financing is confirmed, the process begins with selecting an accredited Durable Medical Equipment (DME) provider. These suppliers are registered entities approved by insurance payers to provide respiratory equipment and services, ensuring compliance with medical standards. They manage the logistical chain, from processing the prescription to equipment installation.
The supplier is responsible for the mandatory delivery and setup of the equipment at the patient’s residence. During delivery, a respiratory therapist or trained technician provides comprehensive training on safe operation. This instruction covers proper flow settings, maintenance requirements (like filter cleaning), and emergency procedures (such as handling power outages). The supplier also maintains responsibility for routine maintenance, repairs, and the scheduled exchange of compressed oxygen cylinders throughout the rental period.
