Common questions

The questions we get asked most, grouped by subject. If yours is not here, call (718) 735-3400 — a person answers.

Insurance and paying

Why do some products show a price and others do not?

Items with a price can be bought outright — add to cart and check out. Items marked Covered by insurance go through your plan instead, and the amount you pay depends on your coverage, so there is no single price to show. Send a request and we will tell you your share before anything is ordered.

What does Medicare actually pay?

For durable medical equipment, Medicare Part B pays 80% of its approved amount after you meet your Part B deductible, which is $283 in 2026. You pay the remaining 20%. If you have a supplement or secondary plan, it may cover part or all of that 20%.

Which plans do you work with?

We bill Medicare, Medicaid and most private plans across New York. There are a great many plans, though, and they do not behave the same way — what one covers outright another may require prior authorization for, and rules differ from one area to the next and between states.

So the honest answer is that it depends on the item and on where you live. Tell us both and we will check your plan before anything is ordered, at no charge.

Do I need a prescription?

For anything going through insurance, yes — your treating doctor has to write an order naming you and the item, with the reason and their signature. For anything you buy yourself, no prescription is needed.

My doctor saw me over video. Does that count?

For most items, yes. Medicare accepts telehealth for the face-to-face requirement in many cases, as long as your doctor documented the examination properly. We check this per item rather than guessing.

How long does approval take?

Verifying your benefits takes a day or two. Getting the order and clinical notes from your doctor's office is usually the slow part. If your plan requires prior authorization — always for power wheelchairs and scooters under Medicare — expect ten to twenty business days on top.

Why is my wheelchair a rental?

Medicare treats standard wheelchairs and hospital beds as capped rentals. It pays month by month for up to 13 months of continuous use, and after that the equipment belongs to you. You are not paying more overall — it is how Medicare structures the benefit.

Can I use insurance for the machine and buy the supplies myself?

Yes, and many people do. It is often faster to order cushions, filters and tubing outright than to wait on a resupply approval, especially if you go through them quickly.

CPAP and BiPAP masks

How do I know my mask size?

Mask sizing is not the same as clothing sizing, and it is not consistent between manufacturers — a medium in one brand can be a small in another. Sizing also differs by mask style: a full face mask is sized to your nose and mouth together, a nasal mask to the bridge and base of your nose, and nasal pillows to your nostril opening.

Most manufacturers publish a printable sizing guide for each model. Print it at 100% scale — not "fit to page" — and hold it to your face. If you are between sizes or unsure, call us with the model name and we will walk through it.

Can I order just the cushion instead of a whole new mask?

Usually yes. Most masks are sold as a complete system — frame, cushion and headgear — but each part is also available on its own. The cushion is the part that wears out first, so replacing it alone is cheaper and usually all you need. Make sure the cushion size matches your frame size.

Will a cushion from one brand fit another brand's frame?

No. Cushions, frames and headgear are designed to fit together within one model line. A ResMed cushion will not seat properly in a Philips frame, and mixing them causes the leaks people blame on the machine.

My mask leaks. Does that mean the wrong size?

Sometimes, but check the simple causes first: a cushion past its life, headgear pulled too tight (over-tightening causes leaks rather than curing them), face cream or oils on the skin, or a cushion seated crooked. If a fresh cushion in the same size still leaks, the size or style is likely wrong.

Replacement parts and how often

How often should CPAP supplies be replaced?

Medicare sets maximum replacement frequencies, and most private plans follow the same schedule. These are ceilings — how often insurance will pay — not targets you have to hit.

ItemMedicare allows
Nasal cushions and nasal pillows2 per month
Full face mask cushions1 per month
Mask frame1 every 3 months
Tubing, standard or heated1 every 3 months
Disposable filters2 per month
Reusable filters1 every 6 months
Headgear1 every 6 months
Chinstrap1 every 6 months
Humidifier water chamber1 every 6 months

Replace sooner if a cushion stops sealing, tubing cracks or clouds, or a filter turns grey. Your own plan may allow a different schedule — ask us and we will check yours.

How do I find the right replacement part for my machine?

Work from the model name printed on the device or the mask frame — for example AirSense 11 or AirFit F30i. Parts are specific to the model, not to the brand as a whole. If the label has worn off, call us with a photo and we will identify it.

Does my humidifier need distilled water?

Yes. Tap water leaves mineral deposits that shorten the life of the chamber and can carry through into the air you breathe. Distilled water costs little and the chamber lasts its full six months.

Orthopedic footwear and bracing

What do the width letters mean?

Shoe widths run narrow to wide, and the letters differ by manufacturer and by whether the shoe is men's or women's. On our product pages the width is part of the product name and, where a shoe comes in several, you choose it on the page. If you normally wear a wide fitting or use a custom insole, order the wider option — insoles take up room.

Does insurance cover diabetic shoes?

Medicare covers one pair of therapeutic shoes with inserts per calendar year for people with diabetes who also have a qualifying foot condition. It requires certification from the doctor treating your diabetes plus a prescription from the podiatrist or other prescriber. It is one of the more paperwork-heavy benefits, and we handle that part.

Do braces and supports come in sizes?

Most do, and they are sized by measurement rather than by clothing size — usually a circumference at a specific point, such as around the knee or the wrist. The measuring instructions come with each product. Measure rather than estimate; a brace that does not fit does not support.

Delivery and returns

Where do you deliver?

Bulky equipment — hospital beds, wheelchairs, lifts, oxygen concentrators — we deliver and set up across the five boroughs of New York City. Smaller items reach further across New York State and beyond, depending on your plan. Anything bought without insurance ships anywhere in the United States.

Will someone set the equipment up?

For equipment that needs it — beds, lifts, oxygen — yes, and we show you how to use it. Items that arrive by courier come with the manufacturer's instructions, and you can call us if anything is unclear.

How long does delivery take?

Five to ten business days, depending on whether the item is in stock and what it is. Small supplies that we hold move at the fast end of that; large equipment we deliver and set up ourselves, and we arrange a time with you.

For anything going through insurance, that clock starts once the claim is approved — the approval itself is the longer wait, and it is described above.

Can I return something?

No — all sales are final. We do not take items back because they turned out to be the wrong size or are no longer needed, opened or not. Almost everything we supply touches skin or carries the air you breathe, and once a package is opened it cannot be made safe for anyone else.

What we do put right: if we sent the wrong item, if it arrived damaged, or if it was faulty out of the box, we replace it and pay the shipping. Equipment supplied through insurance follows the plan's own rules. Rented equipment we collect when you no longer need it — call us, do not dispose of it.

This is exactly why we would rather you called before ordering. Tell us the model or the problem and we will tell you what fits.
