Clinical UM Guideline

This document addresses the medically necessary indications for the use of back-up (or second additional) ventilators in the home setting, for use as a “back-up” machine, if needed.

Mechanical ventilation may be defined as a life support system designed to replace or support normal ventilatory lung function (AARC 2007).

Medically Necessary:

The use of a back-up (second) ventilator in the home setting is considered medically necessary when all of the following criteria are met:

1. The individual cannot maintain spontaneous ventilations for 4 or more consecutive hours; and
2. The individual lives in an area where a replacement ventilator cannot be provided within 2 hours.

The use of a back-up (second) ventilator in the home setting is considered medically necessary for the following additional indication, when applicable:

1. For individuals who require mechanical ventilation during mobility, as prescribed in their plan of care.

Not Medically Necessary:

The use of a back-up (second) ventilator in the home setting is considered not medically necessary when the above criteria are not met.

The following codes for treatments and procedures applicable to this document are included below for informational purposes. Inclusion or exclusion of a procedure, diagnosis or device code(s) does not constitute or imply member coverage or provider reimbursement policy. Please refer to the member's contract benefits in effect at the time of service to determine coverage or non-coverage of these services as it applies to an individual member.

When services may be Medically Necessary when criteria are met:

When services are Not Medically Necessary:
For the procedure codes listed above when criteria for a back-up (second) device are not met.

Mechanical ventilation may be defined as a life support system designed to replace or support normal ventilatory lung function (AARC, 2007). There are a myriad of medical conditions that may cause an individual to require the use of mechanical ventilation for either a short-term or long-term basis. Ventilators can be categorized as either invasive or noninvasive. Invasive mechanical ventilation is defined as the delivery of positive pressure to the lungs via an endotracheal or tracheostomy tube. It is most often used to fully or partially replace the function of spontaneous breathing and gas exchange. Noninvasive ventilation (NIV) may be required part of the time and is delivered through an alternative interface such as a face mask (Hyzy, 2021).

According to the American Association for Respiratory Care (AARC), individuals eligible for invasive long-term mechanical ventilation in the home setting require a tracheostomy tube for ventilatory support, but no longer require intensive medical and monitoring services (AARC, 2007).

The medical necessity criteria in this document for use of back-up ventilators in the home setting are consistent with the recommendations of the AARC Clinical Practice Guidelines for Long-term Invasive Mechanical Ventilation in the Home Setting (AARC, 2007). This document has not been updated since 2007.
