CPAP, Insurance & Your Wallet

# “Covered by insurance” isn't the same as affordable

Insurance plans cover CPAP on paper, then quietly shift much of the cost back to you. Here's how that happens, in plain English, and what you can do about it.

## The short version

If you’ve been told you need CPAP, you’ve probably heard “don’t worry, insurance covers it.” Then the bills arrive. That isn’t bad luck. It comes from four ways the system is set up:

- Your deductible: you pay the full cost until you hit it
- Monthly rental payments that can carry over into the next year, when your deductible starts over
- Middle-man pricing that's often well above what you'd pay to buy the same machine yourself
- A 90-day usage deadline: miss it, and you can lose the machine and everything you've paid toward it

Let’s take each one in turn.

## 1. The deductible comes first

A **deductible** is the amount you pay each year before your insurance starts paying its share. On many plans today that’s a few thousand dollars. Even after you meet it, you often still pay a percentage of each bill (called **coinsurance**) until you hit your yearly **out-of-pocket maximum**.

You payInsurance pays

1. \1. Before you meet your deductible

   You pay every dollar
2. \2. After your deductible

   You pay a share (for example, 20%); insurance pays the rest
3. \3. After your out-of-pocket maximum

   Insurance pays the rest of the year

Who pays each dollar of a medical bill, as your spending adds up over the plan year. Your plan’s numbers may differ.

So “covered” really means: covered after you’ve paid your part. For many people starting CPAP, that part is most of the cost.

## 2. Payments split across the new year

Most plans don’t buy your CPAP machine outright. Instead, the equipment supplier rents it to you month by month, often for 10 to 13 months, and bills your insurance each month. Only at the end do you own it.

Here’s the catch. Say you’re diagnosed in the fall. Between your sleep study and your doctor visits, you’ve met your deductible for the year. Good news, right? Then January arrives, your deductible resets, and the rental payments keep coming:

| When | What happens | What it means for you |
| --- | --- | --- |
| Year 1 (Oct – Dec) | 3 monthly payments | Already met your deductible this year, so you pay only your share (say, 20%) |
| January 1 | Deductible resets |   |
| Year 2 (Jan – Oct) | 10 more monthly payments | Unless you have other large medical bills this year, you pay these in full until your new deductible is met |

An example to show how it works. Your plan’s rental length, deductible, and percentages may differ.

In other words, you can meet your deductible in the year you start CPAP and still pay for much of the machine the following year, unless you happen to meet that year’s deductible too.

## 3. The middle-man markup

Insurance plans usually require you to get CPAP through an equipment company they work with, called a DME (durable medical equipment) supplier. The DME then bills your insurance for the machine, masks, and other assorted items.

Those prices are often considerably higher than what you’d pay for the very same machine and supplies from a reputable seller, such as a well-established online retailer. And in most cases, that higher price lands on you:

- If you haven't met your deductible yet, you pay 100% of the DME's higher price
- If you have met your deductible, you still usually pay a fixed percentage of that higher price (your coinsurance)

Only once you reach your out-of-pocket maximum do you stop paying. Even then, don’t count on the DME to point that out.

## 4. The strings attached: the 90-day usage test

Modern CPAP machines record how long you use them each night, and the supplier can send that data to your insurance. Many plans, following Medicare’s rule, will only keep paying if you:

- Use the machine at least 4 hours a night
- On at least 70% of nights (about 21 of every 30)
- During any 30 consecutive nights within your first 90 days

Miss that bar, and the plan can call it “insufficient use,” stop paying, and the supplier can take the machine back. The rental payments you’ve already made are generally not refunded. Getting CPAP again can mean starting over, usually including a bizarre requirement that you have a repeat sleep study performed.

If something isn’t working in those first weeks, the fix is usually simple: a different mask or a pressure adjustment. But it can take time to find the right mask or get in to see your doctor, and the 90-day clock keeps running the whole time. This adds pressure at the very moment you need support.

## Questions to ask before you say yes

If you’re going through insurance, it’s worth asking your plan and the supplier these questions up front:

- Is the machine rented or bought outright? If rented, for how many months?
- What is my share of each monthly payment, and what happens to it when my deductible resets in January?
- What does my plan require for usage, and by when? Who checks it?
- If I don't meet the usage requirement, do you take the machine back? Do I get any money back?

## Where we stand

We’re a cash-pay clinic, so there’s no insurer between you and your physician, and no equipment company setting deadlines. Our job is to help you get treated and feel better, not to hit someone else’s billing target.

- Your prescription is yours. You can take it to any reputable supplier, online or local, and compare prices — including paying cash, which is often HSA/FSA eligible
- We don't sell CPAP machines or supplies, so we have no reason to steer you toward a particular one
- CPAP is a highly effective treatment for sleep apnea, but it isn't the only one. Tirzepatide (Zepbound), an implanted nerve stimulator that helps keep the airway open, custom dental devices, and symptom-based approaches to treating obstructive sleep apnea with medications are other potentially reasonable options

## CPAP and insurance: common questions

### If my insurance covers CPAP, why am I still getting bills?

Coverage usually means you pay the full price until you meet your deductible, then a fixed percentage of each bill (your coinsurance) until you reach your out-of-pocket maximum. And because CPAP machines are often rented month by month for about a year, those payments can carry over into the next year, when your deductible starts over.

### What is a DME company?

DME stands for durable medical equipment. It's the supplier your insurance plan works with to provide your CPAP machine, masks, and other supplies. They bill your insurance, often at prices considerably higher than a reputable online retailer charges for the same equipment, and they often track your usage data and report it to your plan.

### What is the 90-day CPAP usage rule?

Many insurers, following Medicare's lead, will only keep paying for CPAP if you use it at least 4 hours a night on at least 70% of nights during 30 consecutive nights, within your first 90 days. If you don't, the plan can stop paying and the supplier can take the machine back.

### If my machine is taken back, do I get my money back?

Generally, no. Payments you've already made toward the rental are usually not refunded. Getting CPAP again may mean starting the process over, usually including a bizarre requirement that you have a repeat sleep study performed.

### Can I just buy a CPAP machine myself?

Yes, with a prescription. CPAP machines are prescription devices, but once you have a prescription you can buy from any reputable supplier, and they're commonly HSA/FSA eligible. Buying outright means no rental schedule, no usage deadline, and the machine is yours.

### Is CPAP the only treatment for sleep apnea?

No. CPAP is a highly effective treatment, but tirzepatide (Zepbound), an implanted nerve stimulator that helps keep the airway open, custom dental devices, and symptom-based approaches with medications are other potentially reasonable options.

### Can Nocturne Health prescribe CPAP?

Yes. If testing confirms sleep apnea and CPAP is the right treatment for you, a sleep medicine physician can prescribe it. The prescription is yours to use wherever you choose. An initial virtual consultation is $199.
