CPAP compliance report for insurance: the rule, the paperwork, the shortcut

If your CPAP was supplied through US insurance, there is a clock running. In the first 90 days you must show that you used the machine for at least 4 hours a night on at least 70 percent of nights in a consecutive 30-day window. Miss it and the insurer can stop paying, and the DME can take the machine back. A CPAP compliance report is the document that proves you met the bar. This guide explains the rule, what the people reading the report want, how to produce it by hand, and how the Apnealytics compliance autopilot does it for you.

CPAP compliance report for insurance: the rule, the paperwork, the shortcut

The rule, precisely

The standard US requirement, written into Medicare's coverage criteria and copied by most private insurers:

Window: a consecutive 30-day period
Inside: the first 90 days of therapy
Threshold: at least 4 hours of use per night
Frequency: on at least 70 percent of nights in that 30-day window (21 of 30)

Two things people miss. First, the 30 days must be consecutive, not your best 30 nights scattered across the quarter. Second, a night counts only if it reaches 4 hours; 3 hours 55 minutes is a miss. Partial nights do not add up.

Alongside usage, Medicare also requires a face-to-face follow-up with the treating physician between day 31 and day 91, documenting that the therapy is helping. The compliance report is what that physician reviews.

What the DME wants

Your durable medical equipment supplier is the one who gets paid, so they chase the report. Most DMEs pull data themselves from the machine's modem through the manufacturer's clinician portal (ResMed AirView, Philips Care Orchestrator). They want:

Confirmation that a qualifying 30-day window exists
The dates of that window
Nights used, nights at or above 4 hours, percentage
Average usage on nights used
Usually a residual AHI figure to show the therapy is working, not just being worn

If the modem has been uploading, the DME may already have this. If the modem was off, the machine was in a dead zone, or you bought the machine privately, the SD card is the only record, and you may need to produce the report yourself.

What the insurer and physician want

The insurer wants the DME's attestation plus the physician's follow-up note. The physician wants a one-page summary to read in 90 seconds and attach to the chart: compliance numbers, AHI trend, leak, and a line about how you feel.

How to produce the report by hand

If you need to do it yourself, this works with any tool that shows nightly usage, including OSCAR or a spreadsheet.

Export or list every night from day 1 to day 90
with the usage hours for each. Nights with no use count as zero.
Mark each night as pass or fail
against the 4-hour line.
Slide a 30-day window
from day 1–30, then 2–31, and so on to 61–90. For each window, count the passes.
Find any window with 21 or more passes.
That is your qualifying window. If several qualify, the earliest is usually what the DME wants.
Write it up:
window dates, nights used, nights at or above 4 hours, percentage, average hours on nights used, average AHI over the window.
Attach a trend chart
if you can, and sign and date the page.
Send to the DME and bring a copy to the day-31-to-91 appointment.

Step 3 is the tedious part: sixty-one windows counted by hand. It is exactly the kind of job software should do.

How the Apnealytics compliance autopilot does it

Compliance autopilot is part of the Pro plan ($8.99/month or $99.99/year). It runs on the data you have already uploaded from your SD card.

Upload your card
on the web portal. Nights are parsed from STR.edf; re-uploading only adds new nights.
Open Reports and choose Compliance.
Set your therapy start date if Apnealytics has not inferred it from the first night.
The autopilot scans every consecutive 30-day window
inside your first 90 days and finds the ones where at least 70 percent of nights reached 4 hours. It shows you the earliest qualifying window and any others.
It drafts the letter.
Window dates, nights used, nights at or above 4 hours, percentage, average usage, average AHI and leak P95 for the window, with a plain-language paragraph your physician can paste or sign. You can edit the wording.
Generate the doctor-ready PDF.
The compliance section goes first; a clinical section with the 30-night AHI trend, event composition and pressure summary follows. Health identifiers are included only where you choose.
Send it.
Download the PDF for the DME, or create a clinician share link: tokenized, read-only, aggregate-only, revocable, not indexed by search engines, with health identifiers excluded by default.

If no window qualifies yet, the autopilot tells you how many more 4-hour nights you need and by when, so you know what the next two weeks have to look like.

If you are not going to make it

Be honest with your DME early. Many will work with you: a mask refit, a pressure comfort change or a humidity adjustment often fixes the usage problem, and some insurers allow a restart of the 90-day period after a documented intervention. Showing up with data, even bad data, is better than showing up with nothing.

Keep tracking after day 90

Compliance does not end at 90 days for everyone. Some insurers audit annually, and replacement supplies may depend on continued use. Apnealytics keeps your full history on Pro, and the Goals and streaks panel on every plan keeps the 4-hour line visible. The Year in Sleep recap gives you an annual summary without doing anything.

Questions people ask

What is the 4 hours 70 percent rule for CPAP?

To keep insurance coverage in the US, you must use your CPAP for at least 4 hours a night on at least 70 percent of nights (21 of 30) in a consecutive 30-day window during the first 90 days of therapy. A night under 4 hours does not count, and the 30 days must be consecutive.

How does my insurance know if I am using my CPAP?

Most machines send nightly usage over a built-in modem to the manufacturer's clinician portal, which your DME reads. If the modem is off or you bought the machine privately, the SD card holds the same usage record, and a compliance report generated from the card is the alternative.

What happens if I fail CPAP compliance?

The insurer can stop paying for the machine and supplies, and the DME can reclaim the machine. Some insurers allow a restart after a documented change such as a mask refit. Talk to your DME as soon as you see you are falling short; a usage problem in week 3 is far easier to fix than in week 11.

Can I make my own CPAP compliance report?

Yes. List every night's usage for the first 90 days, mark each against 4 hours, and find a consecutive 30-day window with 21 or more passing nights. Write up the dates, counts, percentage and average usage. Apnealytics Pro's compliance autopilot does the window search and drafts the letter automatically from your SD card data.

Does the compliance report need my AHI?

Strictly, the usage rule is about hours, not AHI. In practice the physician's follow-up note must document that therapy is helping, and a residual AHI figure is the usual evidence. Most compliance reports include average AHI for the window alongside the usage numbers.
