How Often Should CPAP Equipment Be Replaced?

Most sleep therapy supplies are designed to be disposable or semi-disposable. Headgear, filters, masks, and tubing all lose their ability to function properly once used past their intended lifespan. Clogged filters can let dirt into your airway, stretched-out headgear can lead to over-tightening and pressure point pain, and worn masks can develop leaks that undermine your therapy pressure.

Our recommended replacement schedule for CPAP and BiPAP supplies, based on Medicare HCPCS guidelines, is listed below. If you need to replace any of these items, visit our supplies section to shop replacements today.

A Note on This Schedule

This schedule reflects the frequency at which Medicare and many insurance plans typically allow coverage for replacement supplies — it's a guideline for insurance-covered timing, not necessarily a hard rule for how long a specific item will actually last for you. Real-world wear depends on your usage, cleaning habits, and skin oils, among other factors. If a mask, cushion, or piece of headgear is showing signs of wear or reduced performance before its listed interval is up, it's worth replacing sooner rather than tolerating leaks or discomfort until the insurance-covered date arrives.

What Do the HCPCS Codes Mean?

HCPCS (Healthcare Common Procedure Coding System) codes are standardized billing codes used by Medicare and most insurance providers to identify specific durable medical equipment and supplies. If you're working with your insurance provider or a DME supplier on coverage or reimbursement, these codes help ensure you and your provider are referring to the exact same item. See our How to Bill Insurance guide for more on how this works with GoCPAP.

Frequently Asked Questions

Does this schedule mean I have to wait that long to replace an item?

No. This reflects how often insurance typically covers a replacement, not a mandatory waiting period. If an item wears out or stops performing well before its listed interval, replace it sooner.

Will my insurance cover replacements on this schedule automatically?

Coverage details vary by plan and provider. This schedule reflects common Medicare guidelines, but you should confirm your specific plan's coverage and any documentation requirements with your insurance provider or DME supplier.

What's the difference between disposable and non-disposable filters on this schedule?

Disposable filters are designed to be thrown away and replaced monthly. Non-disposable (reusable) filters are washable and typically last longer between replacements, around every 6 months, since they're cleaned rather than discarded after each use.

How often should I replace my CPAP machine?

Generally every 3 to 5 years, though this can vary based on how well the machine has been maintained and whether it's still functioning properly. Consult your provider if you're unsure whether it's time for a new machine.

Do HCPCS codes matter if I'm paying out of pocket?

Not directly for the purchase itself, but they're useful if you plan to submit a claim to insurance or need documentation for reimbursement. See our How to Bill Insurance page for details.
