Online sleep-apnea services promise a prescription without an office visit. Some are legitimate telehealth; others sell a questionnaire. Here’s how to tell the difference, using FDA rules, AASM guidance and Medicare policy.
Why you need a prescription
ResMed’s AirSense 11 user guide states: “In the US, Federal law restricts this device to sale by or on the order of a physician” (AirSense 11 guide). That’s the FDA prescription-device framework (21 CFR 801.109): devices that aren’t safe without practitioner supervision are sold only on a licensed practitioner’s order. So a legitimate U.S. seller should ask for your prescription before shipping a machine.
What a legitimate online pathway looks like
| Step | Legitimate service | Red flag |
|---|---|---|
| Evaluation | A licensed clinician reviews your history and symptoms | Only an online quiz |
| Diagnosis | A sleep test: home sleep apnea test or in-lab study | ”Prescription” issued from a questionnaire alone |
| Result review | Clinician interprets the test and discusses severity and options | No report shared with you |
| Prescription | Specifies device type and pressure settings | Vague or missing settings |
| Follow-up | Check-in on comfort, leaks and data | No follow-up offered |
The AASM strongly recommends that “clinical tools, questionnaires and prediction algorithms not be used to diagnose OSA in adults, in the absence of polysomnography or home sleep apnea testing” (AASM 2017). Home testing is appropriate for uncomplicated adults; people with significant heart or lung disease, neuromuscular conditions, opioid use, stroke or severe insomnia should have an in-lab study. See home vs in-lab sleep tests.
If you’re on Medicare
Medicare’s PAP policy (L33718) requires:
- an in-person clinical evaluation by the treating practitioner before the sleep test
- a qualifying Medicare-valid sleep test
- instruction from the supplier on using the device
- a 12-week trial with adherence of at least 4 hours a night on 70% of nights in a 30-day period
The policy text uses “in-person”. HHZ couldn’t verify from the LCD whether a telehealth visit satisfies it, so ask your practitioner and DME supplier before paying for an online service. Details: Medicare CPAP coverage.
Paying cash with an online prescription
If you’ll buy without insurance, an online prescription plus a cash purchase can work. Compare costs in CPAP without insurance. For reference, the ResMed AirSense 11 AutoSet price we track: $1,004. HSA/FSA funds can often be used for prescribed CPAP (HSA/FSA guide).
Checklist before you pay
| Ask | Why |
|---|---|
| Who’s the clinician, and are they licensed in my state? | You need a legitimate prescriber |
| What sleep test is used? Is it FDA-cleared? | Questionnaires alone aren’t diagnostic (AASM) |
| Will I get the full test report? | Useful for any future supplier or payer |
| What’s in the prescription (device type, pressures, mask)? | Sellers need it |
| What if the test is negative or inconclusive? | AASM: in-lab study should follow |
| Is there follow-up after I start? | Early problems such as leaks need adjusting (mask leak guide) |
| Will my insurer accept it? | Payer rules vary; Medicare says in-person evaluation |
Verdict
An online CPAP prescription is legitimate when it’s based on a real sleep test interpreted by a licensed clinician, not on a quiz. For cash buyers it can be a fast, convenient route. If you’re on Medicare or need insurance to pay, confirm first that the evaluation format meets your plan’s rules.
