Understanding Medicare Coverage for Portable Oxygen Concentrators: What You Need to Know

Understanding Medicare Coverage for Portable Oxygen Concentrators 

Portable oxygen concentrators (POCs) have become an essential technology for individuals with severe respiratory issues, providing the freedom to move about while receiving necessary oxygen therapy. However, given their costs, many patients wonder whether Medicare can help cover these expenses. Let’s delve into the specifics, helping you understand Medicare’s role in covering this vital equipment. 

Basic Overview of Medicare

Medicare is a federal health insurance program primarily for individuals aged 65 and older, but it also covers younger people with certain disabilities or conditions. The program consists of four parts: Medicare Part A (hospital insurance), Part B (medical insurance), Part C (Medicare Advantage plans), and Part D (prescription drug coverage). 

Medical Necessity for Oxygen Therapy

To qualify for coverage of a POC under Medicare, the therapy must be deemed medically necessary. This typically involves conditions such as chronic obstructive pulmonary disease (COPD), emphysema, and other respiratory disorders. A physician’s examination and prescription are usually required to verify the necessity for supplemental oxygen therapy. The need is usually determined based on blood gas studies that demonstrate low blood oxygen levels. 

Medicare Part B and Durable Medical Equipment (DME)

Medicare Part B covers medically necessary services and supplies, including durable medical equipment (DME). Portable oxygen concentrators fall into this category. While Medicare Part B covers DME, it often does not fully cover portable oxygen concentrators due to their higher costs compared to stationary units. 

Patients must first meet their Part B deductible, after which Medicare typically covers 80% of the Medicare-approved amount for the equipment. The beneficiary is responsible for the remaining 20% as coinsurance. It is crucial to confirm that the supplier accepts assignment to ensure you are only responsible for these costs. 

Rental vs Purchase: How Coverage Works

Medicare usually covers oxygen equipment on a rental basis. Typically, Medicare covers the rental of oxygen equipment for 36 months. After this rental period, the supplier must continue to provide the necessary equipment and services for as long as prescribed, up to a total of 5 years, though the payment model may change afterward. 

It’s essential to note that while stationary concentrators are often the default option provided by Medicare-covered plans, acquiring a portable unit may result in additional out-of-pocket costs unless it is specified as medically necessary. 

Medicare Advantage (Part C) Plans

Medicare Advantage plans, also known as Part C, are an alternative to Original Medicare provided by private insurance companies. While they must offer the same coverage as Parts A and B, they can provide additional benefits, including greater coverage for POCs. However, these plans involve specific networks and may require preauthorization. It’s vital to compare different Medicare Advantage plans to choose one that best suits your needs when considering portable oxygen concentrators. 

Tips for Securing Coverage for Portable Oxygen Concentrators

• Consult with Your Doctor: Ensure your physician clearly documents the medical necessity for a portable version of an oxygen concentrator. 
• Choose a Medicare-Approved Supplier: Ensure your supplier is approved by Medicare to avoid extra costs outside of the 20% coinsurance. 
• Review and Understand Your Plan: If you have a Medicare Advantage plan, understand its specific policies and network constraints related to DME coverage. 
• Consider Supplemental Insurance: A Medigap policy can help cover some of the costs not paid by Medicare, such as the 20% coinsurance.
