CPAP Insurance and Prescription Guide for Canada

How prescriptions and coverage fit together

A prescription identifies the prescribed therapy; it does not guarantee that a plan will pay. A diagnostic report may support a claim but may not replace a prescription or payer form. Public programs and private plans may apply different clinical criteria, approved prices, supplier networks, deductibles, co-insurance and replacement limits.

What a CPAP prescription may describe

Depending on the clinical pathway, a prescription or written order may identify the therapy type, pressure or pressure range, comfort features and other treatment instructions. The supplier should match the dispensed equipment and setup to the order and clarify any ambiguity with the prescriber. Do not alter prescribed pressure or choose a different therapy mode to satisfy a benefit category.

A prescription is only one part of the record. Ask whether the payer also requires the interpreted sleep-study report, a specific authorization form, a physician or nurse-practitioner signature, or documentation from another regulated professional.

What to confirm for each purchase

Seven steps to verify coverage

1. Confirm the diagnosis, prescribed therapy and who can issue the required order.
2. Ask the payer for the current benefit wording in writing.
3. Confirm pre-authorization, supplier and product restrictions before purchase.
4. Ask whether machines, masks, humidifiers, supplies and services have separate limits.
5. Request an itemized estimate and compare the amount you may pay yourself.
6. Keep every clinical, supplier, payment and insurer document.
7. After submission, record the claim number and appeal route.

How to claim CPAP on group benefits

1. Get your paperwork together: the sleep study report (showing your AHI) and a CPAP prescription from your clinician.
2. Ask for pre-authorization if your plan requires it (add the items to your cart and select Download a price estimate (PDF) for an itemized estimate you can send with your request), and confirm the maximum amount, how often it will pay for a machine and supplies, and whether it excludes mild sleep apnea.
3. Ask whether a usage report is needed. Some plans ask for proof that you are using CPAP after a trial period; a connected machine makes this easy.
4. Buy from an eligible supplier and get an itemized receipt showing the product, your name and the amount paid.
5. Submit the claim with the receipt, prescription and sleep study report. If you have a spouse’s plan, submit the balance there.
6. Claim what is left as a medical expense on your tax return (CRA).

Common coverage terms in plain language

Eligible expense

An item or service the plan may consider under its contract; eligibility does not mean the full amount will be reimbursed.

Pre-authorization

A review requested before purchase. Confirm what was approved, any conditions and the expiry date.

Approved supplier

A seller or provider that meets the payer’s rules. A licensed product and a payer-approved supplier are separate checks.

Coordination of benefits

The process used when more than one plan may pay part of a claim. Ask which plan receives the claim first.

Reasonable and customary limit

The maximum price a plan recognizes for an item or service, which may be lower than the amount charged.

Public programs and private insurance

Provincial and territorial programs do not all fund CPAP the same way. Employer and personal health plans are contracts that may supplement public coverage and may change at renewal. Confirm the rules that apply to your residence and policy rather than relying on another person’s reimbursement experience.

If you are comparing coverage across the broader sleep-care pathway—including assessments, home sleep testing and consultations—use the Insurance Coverage guide. This page focuses on CPAP prescriptions, equipment and claim documentation.

Tax treatment is separate

The Canada Revenue Agency lists a CPAP machine as a potentially eligible medical expense when a prescription is needed, subject to current rules and the unreimbursed amount. This does not make every mask, accessory, service or purchase automatically eligible. Keep records and seek qualified tax advice for your circumstances.

Product authorization and supplier questions

Health Canada maintains the Medical Devices Active Licence Listing for applicable device classes. Product authorization, prescription, clinical suitability, warranty and insurance eligibility remain separate checks. Confirm the exact model, Canadian warranty, seller, compatibility and return terms before buying. Use the CPAP Buying Guide for the broader purchase decision.

If a claim is denied

Ask for the reason and relevant policy wording in writing. Check for a missing prescription, report, code, supplier credential or authorization. Ask about correction, resubmission and the formal appeal process. Accurate documentation can support review but cannot guarantee approval.

When replacing equipment or changing suppliers

Do not assume that a previous approval automatically applies to a replacement machine, a new mask category or a different supplier. Ask whether a new prescription, pre-authorization, proof of equipment age, repair estimate or confirmation of medical need is required. Confirm warranty options before using an insurance replacement benefit, and keep records that show the exact model and parts supplied.
