How Much Does a Portable Oxygen Concentrator Cost?

Rental vs. Purchase: Cost Comparison

Deciding whether to rent or buy oxygen equipment depends on your medical needs and financial situation. With over 1.5 million people in the U.S. relying on oxygen concentrators for supplemental oxygen therapy[1], understanding the costs tied to each option is crucial. Below, we break down the financial aspects of renting versus purchasing oxygen equipment.

Rental vs. Purchase Models Explained

Renting works like a subscription. You pay a monthly fee that typically includes the equipment, maintenance, repairs, and technical support. The rental company handles delivery and troubleshooting, and you can often switch devices or adjust oxygen flow rates as your condition changes. However, you’ll never own the equipment, and payments continue for as long as you need it.

Buying, on the other hand, means paying a one-time cost to own the device outright. While you’re responsible for maintenance and repairs, you avoid ongoing rental fees. Most oxygen concentrators come with warranties lasting at least three years, offering some peace of mind against early breakdowns[3].

The flexibility between the two options is a key difference. Renting allows you to adapt to changing medical needs, such as switching to a different concentrator type[2]. Purchasing locks you into a specific device unless you buy additional equipment.

Cost Breakdown: Upfront, Maintenance, and Supplies

To understand the full financial picture, you need to look beyond just the initial cost. Here's a comparison of expenses for renting and buying:

When buying, expect to pay $520–$800 for 5L stationary concentrators, $1,300–$1,500 for 10L units, and $2,300–$3,200 for portable models[3]. Additional expenses include replacement filters, oxygen analyzers to test purity, and repair services. Repair costs typically range from $99 plus parts for stationary units to $149 plus parts for portable ones[4]. Regular maintenance, like weekly cleaning and annual or biennial filter replacements, is essential to keep the device functioning properly[3].

"When determining whether your community would save more by renting vs. owning your oxygen concentrators, the key is to look at total cost of ownership over the full life of your equipment", advises Direct Supply[3].

When to Rent vs. When to Buy

So, which option makes more sense for your situation? It depends on how long you’ll need the equipment and your financial plan.

If your need is temporary - such as during recovery from surgery - renting is often the smarter choice. It eliminates the large upfront expense, and you can return the device when you no longer need it.

For long-term users, buying is usually more economical. For example, an $800 concentrator spread over five years breaks down to about $13.33 per month, not including maintenance. Owning also comes with potential tax benefits and ensures you receive a brand-new device[1][2]. Plus, you control the maintenance schedule, allowing you to address issues immediately and maintain consistent access to oxygen therapy[3].

To decide, calculate your total costs, including rental fees or purchase price, filters, and other supplies. Weigh these against your medical needs and budget to find the option that offers the best value for your situation[3].

Oxygen Therapy Cost Calculator: How to Estimate Your Expenses

Using a cost calculator can make budgeting for oxygen therapy much easier by providing tailored cost estimates. These tools help you weigh the long-term costs of renting versus buying equipment while considering factors that might not be immediately obvious. Essentially, they connect the cost details we've discussed with actionable estimates tailored to your situation.

Key Information to Input

Accurate inputs are crucial for reliable cost estimates. Here's what you'll need to include:

• Equipment specifications: Specify the type of device you're considering - whether it's a portable oxygen concentrator, a 5L stationary unit, or a 10L stationary concentrator. Refer to the specifications mentioned earlier for guidance.

• Usage patterns: Detail your daily oxygen usage, required flow rate, and whether you need the device continuously or only during specific activities. This helps estimate energy consumption and the frequency of replacement supplies.

• Rental versus purchase details: For rentals, input your local rental rates and the number of units required. For purchases, include the upfront cost of the device along with estimated expenses for filters and oxygen analyzers[3].

• Maintenance and supplies: Provide details like filter replacement frequency, oxygen analyzer costs, and potential repair expenses. Many calculators also factor in the device's expected lifespan, often based on its warranty period, to calculate total ownership costs[3].

• Energy costs: Since oxygen concentrators typically run for long periods, knowing your local electricity rates is important. Some calculators break down energy costs into daily, monthly, and annual estimates[5].

Example: Breaking Down Costs

Let’s take a closer look at how this works with an example.

Sarah needs a 5L stationary oxygen concentrator for long-term use. If she chooses to purchase, the unit costs $650, and she estimates an annual filter replacement cost of $50. Over five years, her total expenditure would be:

Purchase Cost = $650 + (5 × $50) = $900
This averages to about $15 per month. Comparing this to a rental fee of $85 per month, Sarah would reach a break-even point in just 11 months.

On the other hand, if Sarah opts to rent at $85 per month, her total cost over five years would be:

Rental Cost = 60 × $85 = $5,100

Clearly, buying is more economical for long-term use. However, for short-term needs, renting offers flexibility without a significant upfront cost.

Now, let’s add energy costs. If Sarah’s concentrator uses 300 watts for 16 hours daily, and electricity costs $0.12 per kWh, her energy expense would be about $17 per month. Including this gives a more complete picture of her total costs.

Insurance Coverage and Reimbursement Guide

Factoring insurance coverage into your cost planning can significantly reduce the expenses associated with oxygen therapy. Most insurance plans - including Medicare, Medicaid, and private insurers - offer some level of coverage for oxygen equipment, though the details vary depending on the provider and plan. Taking full advantage of these benefits is an essential step in managing the overall cost of your therapy.

How Insurance Covers Oxygen Therapy

Medicare provides a baseline for many oxygen therapy policies. Under Medicare Part B, oxygen equipment and accessories are classified as durable medical equipment (DME) and are covered if prescribed by a physician for home use. This includes oxygen gas, liquid oxygen systems, and even specialized treatments like hyperbaric oxygen therapy (HBOT), which is used for conditions such as gas embolism, carbon monoxide poisoning, and cyanide poisoning [6][8].

Medicare Advantage (Part C) plans are required to offer the same oxygen therapy benefits as Original Medicare. However, each plan may have its own network of approved providers and cost-sharing rules. To understand the specifics of your plan, it’s best to contact your provider directly [8].

To qualify for Medicare coverage, your doctor must certify that your oxygen therapy is medically necessary, and your DME supplier must be enrolled in Medicare and accept assignment [8].

Private insurance plans often follow similar guidelines but may have varying approval processes or coverage limits. Meanwhile, Medicaid coverage for oxygen therapy depends on the state, with some states offering more comprehensive programs than others.

Once you’ve confirmed your coverage, the next step involves navigating the claims and reimbursement process.

Filing Claims and Getting Reimbursed

The reimbursement process hinges on proper documentation and timing. First, ensure that both your doctor and DME supplier are enrolled in Medicare or are part of your insurance network [7]. If you use a non-participating supplier, you may have to pay upfront and file for reimbursement yourself, which could lead to higher out-of-pocket costs.

Participating suppliers typically handle billing directly, limiting your responsibility to coinsurance and your Part B deductible. Confirming that your supplier accepts Medicare assignment can help you avoid surprise expenses [7].

If your claim is denied, you can reach out to your Medicare Administrative Contractor (MAC) for help with the appeals process. Utilize tools like the MCD Search tool to find relevant keywords, codes, or document IDs from your denial letter. Additional resources are available through Medicare.gov or by calling 1‑800‑Medicare.

Keep detailed records of all expenses related to your oxygen therapy, including equipment, supplies, and maintenance. This documentation will be crucial if you need to appeal a denied claim.

Tips to Reduce Your Out-of-Pocket Costs

Beyond navigating insurance claims, there are other ways to lower your personal expenses:

• Stick to approved providers: Using suppliers within your insurance network ensures you maximize your benefits. Double-check coverage details with your insurer and local DME suppliers before committing to any purchases [10].
• Seek financial assistance programs: If your out-of-pocket costs are high, look into support options from equipment manufacturers or non-profit organizations. For example, hyperbaric oxygen therapy (HBOT) can cost between $250 and $600 per session [10], but some providers offer payment plans or sliding fee scales.
• Leverage utility assistance programs: Running oxygen concentrators can increase electricity bills. Some utility companies offer discounts for customers using medical devices. Contact your local provider to see if this applies to you [9].
• Understand your insurance policies: Review your plan to know what treatments and conditions are covered. For HBOT, most insurance plans cover FDA-approved uses [11]. If your condition isn’t covered, consider clinical trials or research studies that might offer free or reduced-cost treatments [12].

For a practical example, consider Hyperbaric Medical Solutions (HMS). They work with major insurers like Aetna, Cigna, Empire Blue Cross and Blue Shield, and Medicare at their New York locations. HMS also offers free consultations to help patients understand their treatment options and insurance coverage.

Finally, contact your insurance provider directly to get exact cost estimates for your situation. This proactive approach can help you budget effectively and avoid surprises when bills arrive. Since insurance coverage often changes annually, review your benefits during open enrollment to ensure you’re getting the best possible coverage for your oxygen therapy.

Money-Saving Tips for Oxygen Therapy

Once you've figured out your costs and insurance options, there are still plenty of practical ways to cut down on expenses without sacrificing the quality of your oxygen therapy. Here are some tips focused on smart purchases, proper care of equipment, and keeping your therapy aligned with your needs.

Ways to Save Money on Equipment

• Consider refurbished equipment. Buying used portable oxygen concentrators can save you a lot. While new models typically cost between $2,000 and $4,000, refurbished units range from $1,000 to $2,500[14]. This could mean savings of 40–70% compared to buying new. Just make sure to stick with trusted suppliers who offer warranties.

• Look into manufacturer assistance programs. Many manufacturers offer discounts through assistance programs. For instance, the Caire FreeStyle Comfort Portable Concentrator's price can drop from $4,195.00 to $2,395.00, and the Inogen One® G5® from $4,099.00 to $2,495.00 - reducing costs by 35–60%[15].

• Shop around. Use online comparison tools to find the best deals and ask about bulk discounts. This can trim costs by 25–45%[13]. Spending a little extra time comparing prices can pay off.

• Explore generic alternatives. Generic or alternative medical supplies often work just as well as brand-name products. Switching to these can save you 30–60% without compromising safety or functionality[13].

• Check community programs. Some nonprofits, religious organizations, or community health centers offer equipment loans or donations, which can cut your costs by 50–80%[13]. It’s worth asking around in your local area.

• Use tax-advantaged accounts. If you have a Health Savings Account (HSA) or a Flexible Spending Account (FSA), you can use pre-tax dollars to pay for oxygen therapy equipment, saving you even more[13].

Equipment Maintenance to Avoid Repairs

Taking care of your equipment is one of the best ways to avoid costly repairs and extend its lifespan. Regular maintenance can increase a device's life by 30–50% and reduce the need for frequent replacements[13].

• Daily care: Wipe down the exterior of your oxygen concentrator with a soft, damp cloth as needed, and check the oxygen flow daily to ensure everything is working smoothly[16].

• Filter checks: Inspect filters weekly and replace them monthly or as directed by the manufacturer. Clean filters help prevent strain on your device and maintain oxygen purity[16].

• Annual servicing: Professional servicing once a year ensures your equipment stays in top shape. With proper maintenance, portable oxygen concentrators typically last 4 to 7 years[14]. If something goes wrong, consult a professional technician - DIY repairs can void warranties and may be unsafe[16].

Staying on top of maintenance not only saves money but also ensures your therapy remains effective.

Review Your Needs Regularly

Your oxygen therapy needs can change over time, so it's important to reassess regularly to avoid unnecessary costs.

• Follow-up appointments: Schedule check-ins every three to six months to monitor your oxygen saturation levels. For example, after starting long-term oxygen therapy (LTOT), a follow-up at three months helps confirm its necessity, with additional evaluations every 6 to 12 months.

• Reassess LTOT needs: Stable patients with a resting SpO₂ of 92% should undergo a blood gas evaluation to determine whether LTOT is still needed. Patients with signs like peripheral edema, a hematocrit of 55%, or a resting SpO₂ of 94% in cases of pulmonary hypertension should also be evaluated.

• Adjust oxygen dosage: Consult your doctor or respiratory therapist to ensure your dosage is still appropriate for your condition. Adjustments can help optimize your therapy and prevent waste.

• Evaluate equipment needs: As your activity level or lifestyle changes, check if your current equipment setup still suits your needs. Upgrading or downsizing could save you money and improve convenience.

Conclusion

When deciding on oxygen therapy equipment, consider how long you'll need it. Renting is a smart option for short-term use since it avoids hefty upfront costs. However, for long-term needs, buying might make more sense financially. Portable oxygen units typically cost between $2,300 and $3,200, while stationary systems range from $520 to $1,500 [3]. This choice is key to managing costs effectively.

Insurance coverage is another crucial factor. For instance, Medicare Part B covers oxygen equipment and accessories if they’re prescribed for home use [7]. Understanding your coverage and properly handling claims can significantly reduce out-of-pocket expenses.

Don't overlook maintenance. Follow the manufacturer's guidelines to keep your equipment in good condition and avoid expensive repairs [3]. Also, regularly reassess your oxygen requirements. Adjusting equipment or dosage as your condition changes ensures both cost efficiency and proper care. By balancing equipment decisions, insurance benefits, and routine maintenance, you can manage expenses while maintaining high-quality care.
