Home oxygen & portable concentrators
Equipment that gives you extra oxygen at home and while you're out, prescribed by your doctor when your blood oxygen level runs low. We bring it to your home, set it up, and show you how to use it — across Riverside, San Bernardino, Orange, Los Angeles, and San Diego counties.
Will insurance cover it?
Medicare, most major health plans, and managed care cover home oxygen when your doctor documents that you qualify. We check your specific plan and tell you what's covered before anything is delivered.
Billing & insurance →How fast can I get it?
Most equipment is delivered the same day or the next day, once we've received the required orders and documentation from your doctor. We'll call you to schedule.
What will I owe?
We tell you before delivery, not after. If there's a copay or a deductible that applies, you'll hear it from us on the phone first.
What we carry
- Stationary concentrators — for use at home. Plugs into a wall outlet, pulls oxygen from the room air, runs continuously.
- Portable oxygen concentrators (POCs) — battery-powered, for leaving the house, errands, and travel. Shown: Rove 4.
- Conserving devices — deliver oxygen in pulses as you breathe in, so a tank lasts longer.
- Backup cylinders — for power outages and emergencies. Shown: aluminum E-cylinder in cart.
Do I own or rent this equipment?
Your oxygen equipment is rented, not bought. Insurance covers it as a monthly rental for as long as you medically need it. The supplies that go with it — tubing, cannulas, filters — are purchased.
You'll usually have two rentals, not one. Home oxygen is normally set up as two separate pieces of equipment:
- A stationary concentrator, for use at home
- A portable oxygen system, for leaving the house — if you qualify for one
Your insurance pays a monthly rental fee for each one.
What you'll pay. You're responsible for any copay or deductible your plan doesn't cover. We check your specific plan and tell you what to expect before anything is delivered.
After 36 months the payments stop — your equipment doesn't. This is the part people find most confusing, so here it is plainly.
Medicare pays a monthly rental for 36 months. After month 36, no further rental payments are made. We remain responsible for providing that equipment and keeping it serviced for as long as you need it.
That continues through month 60. At that point, if you still medically need oxygen, a new cycle begins and the 36 months start over.

What this means for you:
nothing about your equipment or your service changes at month 36. Same concentrator, same support, same 24/7 number. You don't need to do anything or call anyone.
What to expect at delivery & setup
A Diamond technician brings the equipment to your home at a scheduled time. They'll set it up where you'll actually use it, show you how to turn it on, adjust it, and clean it, and go through the alarms with you so nothing is a surprise later. They stay until you're comfortable using it.
Before we arrive
Please pick a central spot where you'll use the equipment most — by your sofa or bedside works well. Let us know if you have pets, and please have them in a safe place while our technician is in your home.
Living with your oxygen

Common questions about home oxygen
Do I need a prescription for home oxygen?
Yes. Home oxygen is prescribed by your doctor. If your insurance will be covering the rental, your doctor also needs to document the testing that shows you qualify. If you don't have an order yet, call us at (800) 977-3002 and we'll request it from your doctor's office.
How quickly can I get oxygen at home?
Oxygen is usually delivered the same day or the next day after we receive the required orders and documentation from your physician.
If you're being discharged from a hospital, delivery often happens within two hours. We bring the portable equipment to you bedside, then come to your home to set up the stationary concentrator.
In some cases you'll receive equipment directly from the hospital. When that happens we've already coordinated with them, and we'll contact you to arrange delivery of the stationary system.
Will Medicare pay for it?
Yes — as long as you've met the coverage qualifications. That's what all the documentation we request from your doctor is for. This applies to Medicare and to most other insurance. If there's any issue with your coverage, our team will be in touch to talk it through with you.
Do I own the concentrator or rent it?
It's rented. Insurance covers oxygen equipment as a monthly rental for as long as you medically need it — usually as two separate rentals, one for your home concentrator and one for a portable system if you qualify. Supplies like tubing and filters are purchased. See Rented or purchased? above.
What happens after 36 months?
Medicare pays a monthly rental for 36 months. After that, no further payments are made — but we're still responsible for providing and servicing your equipment for as long as you need it, through month 60. If you still medically need oxygen at that point, a new cycle begins. Nothing changes for you: same equipment, same service, same 24/7 support.
What happens if the power goes out?
- Switch to your backup oxygen cylinders right away.
- Contact your utility company — they can usually give you an estimated time for power to be restored.
- Then call us at (800) 977-3002.
- If you're having a medical emergency, call 911.
Can I take oxygen on a plane?
Portable oxygen concentrators supplied by Diamond are all FAA-approved for air travel. Oxygen tanks and cylinders are not permitted on aircraft, in any size.
Each airline sets its own requirements for traveling with oxygen. These usually include how much battery life you need to bring with you, not being seated in an exit row, and giving the airline advance notice that you'll be traveling with oxygen. Check with your airline before you book.
Which areas do you serve?
Riverside, San Bernardino, Orange, Los Angeles, and San Diego counties.
