General information, not medical advice or an insurance coverage decision. MedraxDME operates as an out of network supplier. Coverage, supplier enrollment requirements and patient responsibility depend on the plan and an individual review.
Three different schedules can be involved
Patients may encounter a manufacturer care schedule, a supplier reminder and an insurer’s maximum replacement frequency. These serve different purposes. The product guide explains care and inspection. A reminder prompts a conversation. A coverage policy describes what a plan may consider under its rules.
For Medicare, the PAP LCD lists usual maximum accessory frequencies, subject to coverage of the underlying device and other conditions. A table entry is not an instruction to discard a working part automatically or a guarantee that every shipment will be covered. CMS: PAP Devices, LCD L33718.
Keep the machine and mask model information available when discussing supplies. A mask frame, cushion, headgear and tubing are separate components, and the correct replacement may depend on the exact system rather than the brand alone.
Examples from Medicare’s usual accessory limits
| Accessory example | Code | Usual maximum frequency |
|---|---|---|
| Full face mask | A7030 | One per three months |
| Full face mask replacement cushion | A7031 | One per month |
| Nasal replacement cushion | A7032 | Two per month |
| Headgear | A7035 | One per six months |
| Standard tubing | A7037 | One per three months |
| Disposable filter | A7038 | Two per month |
| Water chamber | A7046 | One per six months |
These are selected examples from CMS: PAP Devices, LCD L33718. Other components have their own entries. The actual code must match the product. Different plans may apply different rules, and the existence of an allowance does not establish current medical need or automatic authorization.
Check what needs replacing
Review the product instructions and inspect the relevant component. A problem described as “the mask leaks” may involve fit, assembly, a worn component or another issue that needs professional help. Do not assume replacing every part is the correct response.
When contacting the supplier, identify which component is affected and whether it is missing, damaged, worn or simply due for a routine review. If a problem affects therapy, contact the sleep care team. A supply request should not lead you to change prescribed pressure or other clinical settings yourself.
Keep a record of when the current part was supplied and what remains unopened. This makes a refill conversation more accurate. It also helps distinguish an early product failure from ordinary replacement need and avoids ordering duplicates of parts you already have.
Refills require a real request
The Medicare contractor’s PAP guidance explains that replacement accessories must be considered in relation to medical necessity and the applicable policy. It also discusses situations involving loss, theft or specific damage, which are different from an ordinary resupply interval. CGS Medicare: PAP supplier questions.
A supplier reminder should lead to a check of what you actually need. It should not be treated as permission to send every possible accessory. Confirm the requested items and quantity before fulfillment, and tell the supplier about unused supplies or a model change.
If you switch suppliers, clarify which company is responsible for the next request. Keep the device and accessory history available through an appropriate secure channel. Do not assume that moving to another supplier resets the plan’s replacement frequencies or removes existing documentation requirements.
Keep a clear supply record
A simple personal record can list the component name, model reference, date received and quantity still unopened. Keep it somewhere accessible for a private supplier conversation. Separate the date a product arrived from the date you began using it, because these may answer different questions during a review.
After a request, note what was agreed and compare the shipment with that record. If a reminder arrives while another supplier is already processing the same item, clarify the situation before authorizing a duplicate request. The record supports an accurate conversation without placing therapy details into a public web form.
Cleaning and replacement are not substitutes for each other
Follow the manufacturer’s instructions for your exact equipment. Resmed’s guidance directs users to the specific device and mask user guides because care procedures differ. Resmed: cleaning CPAP equipment. A generic cleaning method found online may be inappropriate for a particular component.
The FDA cautions about devices marketed to clean CPAP equipment using ozone or ultraviolet light and explains that unapproved claims do not establish safety or effectiveness. Follow the equipment manufacturer’s cleaning instructions and check the FDA information before using an additional cleaning device. FDA: CPAP cleaning devices.
Replacing supplies does not remove the need for appropriate care between replacements. Conversely, cleaning does not repair a torn component or make an incompatible part suitable. Ask the manufacturer or supplier which care instructions apply and which signs call for replacement or technical review.
Compatibility matters as much as the replacement date
Record the full mask name, size and component reference rather than only the manufacturer. A cushion made for a different mask family may not fit, even if it looks similar. Heated tubing can also be specific to a device configuration. Confirm the connection and intended compatibility before accepting a substitute.
If your clinician or fitting professional changes the mask, ask how that affects the remaining supplies and current order. A different mask design may require different cushions or headgear. Do not reorder the old accessories simply because they remain in an online history.
When the shipment arrives, compare the references and quantities with the confirmed request. Contact the supplier about an incorrect item before opening or using it. Keep the packaging and delivery information available while the discrepancy is resolved.
Insurance questions before the next request
- Does the plan cover the underlying PAP therapy and these accessories?
- Which supplier is permitted to fulfill the request?
- Does the exact component and code match the current device or mask?
- What replacement frequency applies to this item?
- What supplies remain on hand?
- Is the request routine, or does a documented loss or damage event need separate review?
- Are an updated order, clinical records or authorization needed?
- What patient responsibility will be explained before fulfillment?
- Who handles a fitting concern or a technical equipment fault?
Use the plan’s answer for your actual benefits. A Medicare schedule reproduced by a retailer does not establish a private plan’s rules, and a product listing does not establish that a supplier can bill your plan.
Request help while keeping health information private
Explore the respiratory supplies catalog to identify equipment and accessories for discussion. MedraxDME is insurance only and out of network; the team must confirm whether it can support your specific request. The catalog does not guarantee a covered replacement or immediate fulfillment.
The insurance callback form collects contact details and optional equipment selections. Do not put sleep study results, diagnoses, member IDs or therapy data into it. Ask for an appropriate secure process if documentation is required.
For symptoms, trouble tolerating therapy or questions about settings, contact the treating sleep professional. For an identified device fault, use the manufacturer’s technical support guidance. Keeping clinical, technical and supply questions distinct helps each reach the right person and avoids treating a refill form as a substitute for care.
Questions and answers
Must I replace every CPAP part at the maximum allowed interval?
No. A coverage maximum is not an automatic replacement instruction. Review actual need, product condition, manufacturer guidance and the plan’s requirements.
Do all insurers follow the Medicare accessory schedule?
No. Confirm your own plan’s rule for each component and supplier.
Can a supply request be used to change my CPAP settings?
No. Clinical settings and therapy concerns should be handled by the treating professional.
