Many insurers, and Medicare in the US, ask for proof that you are using CPAP regularly during your first three months. The rule is simple to state and surprisingly easy to miss by accident. Here is how people clear it without turning therapy into a chore.
Key takeaways
- The usual standard is 4 or more hours of use on at least 70 percent of nights in a consecutive 30-day window within the first 90 days.
- That is 21 qualifying nights out of 30; three hours and fifty-five minutes does not count.
- Habits beat willpower: a fixed routine, a comfortable mask and quick fixes for leak get most people there.
What the rule actually says
For Medicare the standard is use of 4 hours or more per night on 70 percent of nights during a consecutive 30-day period within the first three months of therapy, which works out to 21 nights in 30. Private insurers often copy it, but the details vary by plan and supplier, so confirm yours. Our explainer on the compliance report for insurance covers what suppliers ask for, and CPAP usage hours and adherence explains how usage is measured.
Habits that work
| Habit | Why it helps |
|---|---|
| Wear it for the first nap or TV time | Gets you used to the feel in low-stakes hours |
| Same bedtime routine, mask last | Cues the habit; fewer skipped nights |
| Fix discomfort the first night it appears | Small leaks and pressure marks turn into abandoned nights |
| Put it back on after a night waking | Hours add up from the second half of the night |
| Keep supplies fresh | A tired cushion leaks and drives you to take the mask off |
If the mask is the sticking point, work through the mask leak checklist or try a different style with the Mask Finder. Many people give up on a night because of one fixable annoyance.
Track it without stress
You do not need to refresh a chart every morning. Check once a week: how many of the last 30 nights passed four hours, and what the count needs to be. The free compliance calculator tells you how many of the remaining nights you still need, and Apnealytics shows a goals and streaks panel on every plan so the 4-hour line stays visible.
If you fall behind
Do not wait until day 80. Talk to your equipment supplier early: a mask refit, a comfort setting or a humidity change often fixes a usage problem, and some insurers allow the window to restart after a documented intervention. Showing up with data, even imperfect data, is better than showing up with nothing. A Pro compliance report summarises usage over the period as a PDF you can hand over.
