CPAP Supply Replacement Checker
Medicare sets maximum replacement quantities for CPAP masks, cushions, tubing, filters and other parts, and many suppliers and insurers follow similar schedules. Soft cushions and filters wear out and collect oils and dust quickly, while frames, headgear and water chambers last longer. Pick a part and how long you have been using it.
How it works
Each part maps to the usual Medicare maximum quantity, converted to days: 2 per month is shown as 15 days, 1 per month as 30 days, 1 per 3 months as 90 days and 1 per 6 months as 180 days. Days left = interval minus days used.
Example
A nasal pillow insert used for 20 days: the usual maximum is 2 per month (about every 15 days), so it is past the usual replacement point.
Assumptions and limits
- Intervals are the maximum quantities in the Medicare PAP policy (LCD L33718), which limit how often Medicare pays, not a medical rule about when a part fails.
- Your plan, supplier and the manufacturer's instructions may differ. Replace any part early if it is cracked, torn, stiff or leaking.
- Monthly quantities are approximated as 30 day months.
Frequently asked questions
Why replace cushions so often?
Silicone and gel cushions absorb skin oils and soften, which leads to leaks, noise, red marks and less effective therapy. Daily cleaning helps them last, but they still wear out.
Is it the maximum or the required schedule?
The Medicare figures are the most it will pay for, for example up to one full face cushion per month. You only get a replacement when it is needed, and suppliers usually check with you first.
Does the machine itself get replaced?
Medicare generally treats CPAP and BiPAP machines as having a reasonable useful lifetime of 5 years before replacement is considered.
