Noninvasive Ventilation

S9™ VPAP™ ST-A with iVAPS
Intelligent. Personalized. Automatic.

iVAPS is ResMed's intelligent Volume-Assured Pressure Support featured in the S9 VPAP ST-A. It monitors ventilation and adjusts to your respiratory rate, targets and maintains alveolar ventilation, and automatically adjusts Pressure Support as needed to accommodate your unique needs, so you can enjoy the benefits of effective treatment.

 

Intelligent: Unlike other ventilation modes that only target tidal volume, iVAPS targets alveolar ventilation, accounting for anatomical dead space to ventilate you more effectively. If necessary, an intelligent Backup Rate (iBR) allows you to spontaneously trigger the device, while matching the backup breath to your natural rate.

 

Personalized: iVAPS customizes therapy based on your individual needs. Whether your clinician chooses to use the device's Learn Targets feature or prefers to set your targets directly, iVAPS makes it easy to personalize therapy.

 

Automatic: iVAPS continuously monitors and adjusts Pressure Support to achieve and maintain target alveolar ventilation, even as your needs changes over time (such as during different stages of sleep). The intelligent algorithm provides rapid, gentle automatic Pressure Support so you can sleep more comfortably with fewer disruptions.

 

Important information about Medicare

We have provided this information to assist you in understanding Medicare coding and coverage for NIV respiratory assist devices (RADs). You may also download a pdf of Medicare’s RAD guidelines.

RADs are used to administer NIV therapy, sometimes referred to as noninvasive positive pressure ventilation (NPPV). ResMed’s VPAP™ series of NIV products combines increased comfort with exceptional synchronization technology and a high level of clinical control to help protect every breath and achieve better treatment outcomes.

 

Medicare Criteria for RADs
Medicare has specific coverage criteria for those patients with clinical disorder groups characterized as follows in the three groups below. Please refer to the local coverage policy for additional details.1

 

Restrictive Thoracic Disorders

1. Documentation in patient’s medical record of a neuromuscular disease (eg, amyotrophic lateral sclerosis) or a severe thoracic cage abnormality (eg, post-thoracoplasty for TB); and
2. An arterial blood gas PaCO2, done while awake and breathing the patient’s FiO2, is ≥ 45 mm Hg; or sleep oximetry demonstrates oxygen saturation ≤ 88% for ≥ 5 minutes (minimum 2-hour recording time), done while breathing the patient’s prescribed FiO2; or for a neuromuscular disease (only), maximal inspiratory pressure is < 60 cm H2O or forced vital capacity is < 50% predicted; and
3. COPD does not contribute significantly to the patient’s pulmonary limitation.

 

If all of the above criteria are met, based upon the judgment of the treating physician either an E0470 (non-backup bilevel) or E0471 (backup rate bilevel)  will be covered for patients within this group of conditions for the first three months of therapy.

 

Severe COPD

1. An arterial blood gas PaCO2, done while awake and breathing the patient’s prescribed FiO2, is ≥ 52 mm Hg; and
2. Sleep oximetry demonstrates oxygen saturation ≤ 88% for ≥ 5 minutes (minimum 2-hour recording time), done while breathing oxygen at 2 LPM or the patient’s prescribed FiO2 (whichever is higher); and
3. Prior to initiating therapy, obstructive sleep apnea (OSA) and treatment with continuous positive airway pressure
   (CPAP) has been considered and ruled out.

 

If all above criteria are met, an E0470 (non-backup bilevel) device will be covered for the first three months of therapy. An E0471 (backup rate bilevel) device will be covered for a patient with COPD if additional criteria are met. Please see continued coverage information in the extended policy for qualification prior to and post 61 days.

 

Hypoventilation Syndrome

An E0470 (non-backup bilevel) device is covered if the following are met:

1. An initial arterial blood gas PaCO2, done while awake and breathing the patient’s prescribed FiO2, is ≥ 45 mm Hg; and
2. Spirometry shows FEV1/FVC ≥ 70% and an FEV1 ≥ 50% of predicted; and
3. An arterial blood gas PaCO2, done during sleep or immediately upon awakening, and breathing the patient’s prescribed FiO2, shows the beneficiary’s PaCO2 worsened ≥ 7 mm Hg compared to original result; or
4. A facility-based PSG demonstrates oxygen saturation ≤ 88% for ≥ 5 minutes of nocturnal recording time (minimum 2-hour recording time) not caused by obstructive upper airway events (ie, AHI less than 5).

 

An E0471 (backup rate bilevel) device is covered if the following criteria are met:

1. A covered E0470 (non-backup bilevel) is being used.
2. Spirometry shows FEV1/FVC ≥ 70% and an FEV1 ≥ 50% of predicted; and
3. An arterial blood gas PaCO2, done while awake and breathing the patient’s prescribed FiO2, shows the beneficiary’s PaCO2 worsened ≥ 7 mm Hg compared to ABG result used to qualify for E0470 (non-backup bilevel); or
4. A facility-based PSG demonstrates oxygen saturation ≤ 88% for ≥ 5 minutes of nocturnal recording time (minimum 2-hour recording time) not caused by obstructive upper airway events (ie, AHI less than 5), while using an E0470 (non-backup bilevel).
   
   Follow-up Documentation Requirements Continued Coverage for E0470 (non-backup bilevel) and E0471 (backup rate bilevel)

 

Devices Beyond First Three Months of Therapy

The following items must be obtained no sooner than 61 days after initiating use of the device to document continued coverage beyond three months:

1. Signed and dated statement completed by treating physician declaring that the patient is compliant, using the device an average of four hours per 24-hour period, and that the patient is benefiting from its use; and
2. Progress of relevant symptoms.
