Implant candidacy guide

Inspire candidacy: an implant evaluation has several independent gates

Hypoglossal nerve stimulation can treat selected adults with obstructive sleep apnea, but a marketing quiz cannot establish eligibility. Diagnosis, severity, PAP experience, anatomy, drug-induced sleep endoscopy, medical safety, and payer criteria all need direct verification.

Direct answer

Who qualifies for Inspire therapy?

Current candidacy generally requires an adult with obstructive sleep apnea within labeled severity limits, inability to use or benefit from PAP as defined by the treating pathway, a suitable airway-collapse pattern, and no disqualifying anatomy or excessive central and mixed events. Exact FDA labeling and payer rules must be checked at the evaluation date.

  • Body-mass criteria and coverage limits can differ from FDA labeling and change over time.
  • DISE supports anatomy selection but does not guarantee response.
  • Implant surgery, activation, titration and long-term device management are separate steps.

At a glance

  • Bring the complete diagnostic study, not only AHI.
  • Document PAP trials and structured troubleshooting.
  • Review central and mixed event proportion.
  • Confirm DISE findings, anatomy, surgical risk and MRI considerations.
  • Verify insurer criteria before assuming approval.

Confirm the diagnosis and range

The implant is for selected obstructive—not predominantly central—sleep apnea.

Review study date, AHI, oxygen, position, stage, central and mixed events, and whether weight or health has changed since testing.

Define PAP difficulty accurately

Dislike and documented intolerance may not be treated the same.

Bring device downloads, mask trials, pressure work, humidification, coaching and the clinician’s conclusion about inability to use or benefit.

DISE examines collapse pattern

Certain airway behavior affects candidacy.

Ask what sites and directions collapsed, how findings were scored, and whether the result meets current implant and payer requirements.

Surgery is only the beginning

Healing, activation, programming and titration require multiple visits.

Discuss incision, nerve and tongue effects, infection, device sensation, restrictions, battery life, future procedures and follow-up sleep testing.

Medical and device context matters

Anatomy, neurologic function and implanted devices can change safety.

Review swallowing or speech problems, prior neck surgery, pregnancy, MRI needs, pacemakers and conditions affecting surgical or anesthesia risk.

Coverage is a separate gate

FDA approval does not obligate every insurer to pay.

Obtain current medical-necessity, network, prior-authorization and documentation requirements. Ask which services—DISE, surgery, activation, programming and testing—are billed separately.

Appointment checklist

Bring evidence for every implant gate

Avoid repeating studies or promising eligibility before the team sees the complete record.

  1. 1

    Sleep-study record

    Bring AHI, event types, oxygen, stage, position and study quality.

  2. 2

    PAP record

    Bring modes, settings, mask trials, downloads, side effects and clinician-directed troubleshooting.

  3. 3

    Anatomy record

    Bring ENT exam, prior airway surgery, DISE report and imaging if requested.

  4. 4

    Medical and coverage record

    List conditions, implants, MRI needs, medicines, insurer criteria and authorization status.

Common questions

Questions patients ask first

What disqualifies someone from Inspire?

Predominantly central or mixed apnea, an unsuitable collapse pattern, anatomy or health concerns, and failure to meet current labeling or payer criteria may affect candidacy.

Is there a BMI limit?

FDA labeling and insurer thresholds may differ and can change. Verify the current rule with the implant center and payer.

Does Inspire replace CPAP immediately?

No. Implantation is followed by healing, activation, programming and efficacy testing; the team directs when other therapy changes.

Is approval guaranteed after DISE?

No. DISE is one gate among diagnostic, PAP, anatomy, safety and coverage requirements.
