If CPAP isn’t working for you, you have options. This guide sticks to what FDA approvals, AASM guidelines and Medicare policy actually say. Your sleep physician decides which fits you.
The options at a glance
| Option | What it is | Who it’s for (per source) | Source |
|---|---|---|---|
| Inspire (upper airway stimulation) | Implanted hypoglossal nerve stimulator with a patient remote | Moderate to severe OSA (AHI 15–100), age 22+, failed or intolerant of PAP, no complete concentric soft-palate collapse | FDA SSED |
| Oral appliance | Custom mouthpiece that advances the lower jaw | OSA patients intolerant of CPAP or preferring an alternative | AASM/AADSM 2015 |
| Zepbound (tirzepatide) | Prescription injection | Moderate to severe OSA in adults with obesity, with diet and exercise | FDA |
| Other PAP modes | Auto CPAP, BiPAP | When standard CPAP is uncomfortable or ineffective | APAP vs CPAP vs BiPAP |
Inspire: FDA criteria
The FDA’s June 2023 approval (P130008/S090) raised the upper AHI limit from 65 to 100 and the BMI warning limit from 32 to 40 (FDA).
| Criterion | FDA labeling |
|---|---|
| Severity | AHI 15 to 100 |
| Age | 22 and older; also 18–21 under conditions; 13–18 with Down syndrome (AHI 10–50) under further conditions |
| PAP | Confirmed to fail (AHI over 15 despite PAP) or can’t tolerate PAP |
| Anatomy | No complete concentric collapse at the soft palate |
| BMI | Safety and effectiveness data available up to BMI 40 |

Oral appliances: AASM/AADSM guideline
| # | Recommendation | Strength |
|---|---|---|
| 1 | Oral appliances rather than no therapy for primary snoring (without OSA) | Standard |
| 2 | When prescribed for OSA, a qualified dentist should use a custom, titratable appliance over non-custom devices | Guideline |
| 3 | Consider oral appliances, rather than no treatment, for OSA patients intolerant of CPAP or preferring alternate therapy | Standard |
| 4 | Qualified dentists should provide follow-up to watch for dental side effects or bite changes | Guideline |
| 5 | Follow-up sleep testing to confirm or improve efficacy | Guideline |

Medicare coverage of oral appliances
Medicare’s DME policy (LCD L33611) covers a custom-fabricated mandibular advancement appliance (E0486) when all of these are met:
| Criterion | Requirement |
|---|---|
| A | In-person clinical evaluation by the treating practitioner before the sleep test |
| B | Medicare-covered sleep test: AHI/RDI of 15 or more (min 30 events), or 5–14 with qualifying symptoms or conditions, or over 30 with PAP not tolerated or contraindicated |
| C | Ordered by the treating practitioner after reviewing the sleep test report |
| D | Provided and billed by a licensed dentist (DDS or DMD) |
A prefabricated appliance (E0485) is denied as not reasonable and necessary.
Zepbound (tirzepatide)
On December 20, 2024, the FDA approved Zepbound “for the treatment of moderate to severe obstructive sleep apnea (OSA) in adults with obesity, to be used in combination with a reduced-calorie diet and increased physical activity” (FDA). Side effects listed by the FDA include nausea, diarrhea, vomiting, constipation, abdominal pain, injection-site reactions, fatigue, allergic reactions, burping, hair loss and reflux. It causes thyroid C-cell tumors in rats, and the FDA says it shouldn’t be used by people with a personal or family history of medullary thyroid cancer or MEN 2. Other GLP-1 drugs aren’t covered by this approval. Insurance coverage for this use varies; HHZ hasn’t verified Medicare coverage.
How to choose
| If you… | Discuss |
|---|---|
| Find the mask the problem | Try mask changes first (best CPAP masks, mask leak) |
| Find the pressure uncomfortable | Auto CPAP or BiPAP (APAP vs CPAP vs BiPAP) |
| Can’t tolerate CPAP or prefer an alternative | Custom oral appliance (AASM) |
| Have moderate to severe OSA and truly can’t use PAP | Inspire evaluation |
| Have OSA and obesity | Zepbound, with your clinician deciding how it fits with PAP |
Verdict
Don’t just stop CPAP. Fix comfort problems first, then work through the alternatives with your sleep physician. A custom oral appliance has guideline support and Medicare coverage criteria. Inspire is for moderate to severe OSA after PAP failure, with specific FDA criteria. Zepbound is now an FDA-approved option for OSA with obesity. Whatever you choose, confirm it works with follow-up testing.
