The exact monthly cost of using portable oxygen therapy will vary, depending on what type of equipment you are using, as well as the model and brand. How much you will have to pay per month depends on your insurance company, or if any special payment arrangements have been made between you are your medical supplier.
If you have medicare, or a medical insurance company that works in much the same way, they will cover refills, the delivery of equipment, setting up the equipment, as well as maintenance. Accessories and other necessary supplies you will need will also be covered, patient education to instruct you on operating the equipment and more. These costs cover your equipment as a rental.
As of 2006, Medicare allows $7,215 for 36 months to cover oxygen concentrators that cost an average of $587 sale price. Every 4 months, suppliers do maintenance checks on concentrators and other oxygen therapy equipment. This is usually covered by the insurance company, and will definitely be mostly covered by medicare. If you are covered by medicare, you will still need to cover 20% of the cost.
