Coverage Criteria for Home Ventilators

Initial Therapy — Restrictive thoracic disorders

Covered when ALL of the following are met for initial 3-month request

Restrictive thoracic disorders initial criteria: 1) Documentation of a neuromuscular disease (e.g., amyotrophic lateral sclerosis) or a severe thoracic cage abnormality (e.g., post‑thoracoplasty or severe kyphoscoliosis) AND one of the following taken while the member was stable (not in acute respiratory failure): (a) PaCO2 ≥ 45 mm Hg measured while awake and breathing room air or on prescribed oxygen; OR (b) sleep oximetry demonstrating O2 saturation ≤ 88% for at least five minutes while breathing prescribed O2; OR (c) if neuromuscular disease is present, maximal inspiratory pressure < 60 cm H2O or forced vital capacity < 50% predicted. 2) Documentation that the member could not be appropriately treated with a respiratory assist device (RAD). 3) Documentation that the noninvasive home ventilator will not be used to provide RAD or CPAP therapy (i.e., will be used to provide average volume‑assured pressure support). 4) COPD does not contribute significantly to the pulmonary limitation.PaCO2 >= 45 mm Hg; Sleep oximetry <=88% for >=5 minutes; MIP <60 cm H2O; FVC <50% predicted

Initial certification period is three months.

Initial Therapy — Severe COPD

Covered when ALL of the following are met for initial 3-month request

Severe COPD initial criteria: 1) An arterial blood gas PaCO2 measurement obtained while awake and breathing at baseline with the prescribed FIO2 ≥ 52 mm Hg. 2) Prior to initiating therapy, sleep apnea and CPAP treatment have been considered and ruled out (formal sleep testing not required if the record demonstrates sleep apnea is not the predominant cause of awake hypercapnia or nocturnal desaturation). 3) Documentation that the member could not be appropriately treated with a respiratory assist device (RAD) AND that the noninvasive home ventilator will not be used to provide RAD or CPAP therapy (i.e., will be used to provide average volume‑assured pressure support).PaCO2 with FIO2 >= 52 mm Hg

Initial certification period is three months.

Initial Therapy — Obesity hypoventilation syndrome (OHS)

Covered when ALL of the following are met for initial 3-month request

OHS initial criteria: 1) BMI ≥ 30. 2) An initial arterial blood gas PaCO2 done while awake and breathing at baseline with the prescribed FIO2 ≥ 45 mm Hg. 3) Sleep‑disordered hypoventilation documented by polysomnography and other conditions are not the primary cause of hypoventilation (e.g., lung disease, chest wall disorder other than obesity mass loading, medication use, neurologic disorder, muscle weakness, congenital or idiopathic central alveolar hypoventilation). 4) Documentation that the member could not be appropriately treated with a respiratory assist device (RAD) AND that the noninvasive home ventilator will not be used to provide RAD or CPAP therapy (i.e., will be used to provide average volume‑assured pressure support).BMI >= 30; PaCO2 with FIO2 >= 45 mm Hg

Initial certification period is three months.

Continuation Therapy

Covered when ALL of the following are met for continued use

Continuation criteria: A) Device is used at least an average of four hours per 24‑hour period. B) Documentation supports both: (1) ongoing benefit from use of the device; AND (2) the noninvasive home ventilator is not being used to provide RAD or CPAP therapy (i.e., is being used to provide average volume‑assured pressure support).>= 4 hours/24 hr

Applies after the initial three‑month certification period.

Invasive Ventilator Use

Covered when criteria for long-term/chronic invasive ventilator support are met

Invasive ventilator: Initial and ongoing use of an invasive ventilator is medically necessary for long‑term or chronic conditions that impair the ability to maintain adequate respiration (examples: neuromuscular disease, thoracic restrictive disease, or chronic respiratory failure following COPD).N/A

Detailed physiologic thresholds are referenced to clinical judgment; see policy for examples of qualifying conditions.

Second/Back-up Ventilator

Second or back-up ventilator is medically necessary for one of the following

Second/back-up ventilator: A) A second ventilator to serve a different purpose from the first ventilator based on medical needs (e.g., two different types such as a negative‑pressure device with chest shell for part of the day and a positive‑pressure ventilator with mask for the remainder). OR B) A back‑up ventilator when: (1) the member is wheelchair‑confined and requires a wheelchair‑mounted ventilator during the day and another ventilator of the same type for use while in bed because the wheelchair‑mounted ventilator cannot be positioned close enough to the bed; OR (2) the member resides in a remote area with poor emergency access.N/A

Second ventilator may be same or different type depending on need.

Overlap syndromes — Medical director review

Special review requirement

Overlap syndromes: Noninvasive home ventilator requests for overlap syndromes (presence of more than one condition, such as COPD and sleep apnea) require secondary review by a medical director.N/A

Medical director review required.

The policy requires clear documentation that the noninvasive home ventilator will be used to provide average volume assured pressure support rather than serving as a respiratory assist device (RAD) or a continuous positive airway pressure (CPAP) device. For initial indications (restrictive thoracic disorders, severe COPD, and obesity hypoventilation syndrome) the request must include explicit documentation that the member could not be appropriately treated with a RAD and that the ventilator will not be used to provide RAD or CPAP therapy. (Initial certification is for 3 months.)

Coverage decisions under this clinical policy are a guide to medical necessity and are subject to the terms, conditions, exclusions and limitations of the member’s coverage documents. Where applicable, state Medicaid provisions and other statutory or regulatory requirements take precedence over this policy when they conflict with its provisions.

Use of a noninvasive home ventilator solely to provide RAD or CPAP therapy does not meet the medical necessity criteria in this policy. Both initial and continued coverage require documentation that the ventilator is being used to provide average volume assured pressure support and not solely as a RAD/CPAP device; continued coverage additionally requires average use of at least 4 hours per 24-hour period with evidence of ongoing benefit.

Provider Actions, Prior Authorization, and Documentation

Prior Authorization

Prior authorization: initial 3-month requests and continuation evidence required

Initial prior authorization requests for noninvasive home ventilators must be submitted for the first three-month certification period and meet the indication-specific criteria for the requested diagnosis. Continued authorization after the initial three-month period requires documentation that the device is used at least an average of four hours per 24-hour period and shows ongoing benefit, and that the ventilator is not being used to provide RAD or CPAP therapy.

Initial requests: first 3 months and must meet the specific indication criteria for restrictive thoracic disorders, severe COPD, or OHS.
Continuation: average device use ≥ 4 hours/24 hr, documentation of ongoing benefit, and confirmation device is not used for RAD/CPAP.

Note

Review applicable Medicare NCDs/LCDs prior to applying policy

For Medicare members/enrollees, review all applicable Medicare National Coverage Determinations (NCDs), Local Coverage Determinations (LCDs), and Medicare Coverage Articles before applying this clinical policy to ensure consistency with Medicare coverage rules.

Background

Respiratory failure refers to the inability to adequately oxygenate or eliminate carbon dioxide and may present as an acute or chronic condition. Noninvasive ventilation (NIV) delivers positive pressure via external interfaces (for example masks or mouthpieces) to support ventilation in patients with conditions such as neuromuscular disease, severe thoracic cage abnormalities, obesity hypoventilation syndrome, or chronic respiratory failure related to COPD. NIV can improve symptoms, gas exchange, quality of life, and reduce hospital readmissions and mortality in selected patients. In contrast, invasive ventilatory support is delivered through an invasive airway (tracheostomy or endotracheal tube) and is used when patients cannot sustain adequate spontaneous ventilation or airway protection. This policy defines clinical thresholds and documentation requirements to identify patients for whom home NIV or invasive ventilator support is medically necessary.

Definitions

inv-25: Definition — Noninvasive ventilation (NIV)

DefinitionAdministration of positive pressure to the lungs using external interfaces such as nasal masks, orofacial masks, full face masks, mouthpieces, nasal pillows, or helmets.

Primary goalManage acute and chronic respiratory failure, improve symptoms, quality of life, and reduce readmission and mortality

Interfaces listedExamples include nasal mask, oronasal mask, nasal prongs, full-face mask

inv-26: Definition — Invasive ventilatory support

DefinitionAdministration of positive pressure to the lungs through an invasive interface such as a tracheostomy tube or endotracheal tube.

IndicationUsed when patients cannot breathe spontaneously or protect their airway, or ventilatory needs exceed capability

Refer to the CMS website for current NCDs and LCDs prior to applying policy criteria.

Step Therapy

Consider CPAP/sleep apnea and rule out prior to ventilator for severe COPD

Before initiating home ventilator therapy for severe COPD, consider and rule out sleep apnea and treatment with CPAP; formal sleep testing is not required if the medical record shows sleep apnea is not the predominant cause of awake hypercapnia or nocturnal desaturation.

Document that CPAP and evaluation for sleep apnea were considered and ruled out, or that records demonstrate sleep apnea is not the predominant cause of hypercapnia/desaturation.

Note

Ensure submission of all indication-specific clinical findings before authorization

Provide the specific clinical findings and supporting documentation required by the indication being requested; lack of required physiologic measurements or documentation may prevent approval.

Include arterial blood gas PaCO2 measurements (with prescribed FIO2 thresholds where specified).
Include sleep study or sleep oximetry documentation when required.
Document inability to be treated with a RAD and that ventilator will not be used for RAD/CPAP.

Documentation Required

Required clinical documentation: diagnoses, physiologic measures, RAD/CPAP justification, and device use

Clinical documentation must include the diagnosis and the relevant physiologic measurements taken while the member was stable, plus evidence that a RAD/CPAP is inappropriate and, for continuation, records of average daily device use and ongoing benefit.

Diagnosis (e.g., neuromuscular disease, severe thoracic cage abnormality, OHS).
PaCO2 values with the applicable FIO2 thresholds and PaCO2 ≥ 45 mm Hg where required.
Sleep oximetry or polysomnography results when required.
Maximal inspiratory pressure or FVC for neuromuscular disease when specified.
For continuation: documentation showing average use ≥ 4 hours per 24-hour period and ongoing clinical benefit.

Note

Follow Health Plan effective date and administrative procedures

This clinical policy is effective as of the date determined by the Health Plan; providers must follow Health Plan notification and administrative procedures and recognize the policy may be changed, amended, or withdrawn by the Health Plan.

The posted date may not equal the effective date; comply with any applicable legal or regulatory provider notification requirements.
State Medicaid provisions take precedence where they conflict with this policy.

Denial Risk

Denial triggers: missing required clinical criteria

Requests lacking required clinical criteria (for initial or continued use) — for example, missing PaCO2 values with required FIO2, absent sleep study or sleep oximetry documentation, failure to document RAD/CPAP inappropriateness, or no documentation of average device use for continuation — may be denied.

Missing arterial blood gas PaCO2 (with required FIO2) for the applicable indication.
Absent sleep testing or sleep oximetry when required by the indication.
No documentation that RAD/CPAP is inappropriate or that the ventilator will not be used to provide RAD/CPAP.
For continuation requests, failure to show average use ≥ 4 hours/24 hr and ongoing benefit.

Denial Risk

Denial risk: coverage documents, exclusions, and administrative rules may limit payment

Coverage determinations are subject to the terms, conditions, exclusions and limitations of the member's coverage documents and to state and federal requirements; administrative policies and benefit terms may affect payment even when clinical criteria are met.
