Description

Individuals with impaired ability to cough due to respiratory muscle weakness or pulmonary restriction have difficulty clearing secretions from the lungs. The accumulated secretions may allow growth of pathogens, leading to a higher risk for chronic infections and deterioration of lung function as the bronchial tubes can be occluded. Conditions that can lead to this problem include amyotrophic lateral sclerosis (ALS), bronchiectasis, cystic fibrosis (CF), muscular dystrophy, myasthenia gravis and spinal cord injuries.

Airway clearance devices are an alternative to standard manual chest physiotherapy (CPT), which includes percussion, postural drainage, forced expiratory maneuvers, huffing and coughing. These techniques usually require the aid of another individual. Several types of airway clearance devices have been developed, which include, but may not be limited to:

  • High-frequency chest compression vests – These consist of an air generator and an inflatable vest that covers the chest. Increases in air pulses are delivered to the vest with oscillating airflow patterns, causing external manipulations of the chest. Examples of these devices include, but may not be limited to, AffloVest, InCourage System, Monarch Airway Clearance System, SmartVest Airway Clearance System, SmartVest SQL Airway Clearance System and Vest Airway Clearance System.
  • Oscillating positive expiratory pressure (OPEP) devices – These deliver mini bursts of oxygen while also delivering therapeutic aerosols through a nebulizer. The intended purpose of this treatment is that through a combination of bursts of oxygen and medication, it loosens secretions, stimulates cough and increases sputum production. An example of this type of device includes, but may not be limited to, the Impulsator.
  • Cough-assist devices with a facemask that covers the nose and mouth, delivering alternating positive and negative pressure allowing air to be pumped into the lungs and then rapidly evacuated. This produces a high expiratory flow rate from the lungs and stimulates a cough and increasing secretion clearance. Examples of these include, but may not be limited to, BiWaze Cough System, CoughAssist and Synclara.
  • Mechanical percussors – These electrical devices provide clapping, percussion and/or vibration to the external chest wall and are used in place of manual chest percussion to assist with secretion clearance. Examples of these types of devices include, but may not be limited to, Frequencer and Vibralung.
  • Positive expiratory pressure (PEP) devices – These devices increase resistance to expiratory airflow which helps improve secretion clearance by creating pressure in the lungs and preventing airway closure. The individual breathes into the device normally, but breathes out harder against resistance. An example of this device includes, but may not be limited to, Pari Pep S.

TheraPEP is another PEP device; however, this device is available over-the-counter without a prescription.

(Refer to Coverage Limitations section)

Hand-held devices combine PEP with high-frequency air flow oscillations using a stainless-steel ball or a counterweight plug and magnet. These devices utilize deep breathing and forced exhalation to create a vibration of the airway walls which loosen secretions. An example of this type of device includes, but may not be limited to, Flutter.

Acapella and Aerobika are examples of other OPEP devices; however, these devices are available over-the-counter without a prescription.

(Refer to Coverage Limitations section)

The Volara System and BiWaze Clear System combine several noninvasive therapies into one device. These devices purportedly provide oscillation and lung expansion (OLE) therapy using PEP, oscillation and delivery of aerosol medications.19 Volara was voluntarily recalled by the manufacturer on April 26, 2022 due to the risk of respiratory distress in ventilated patients during home use with the US Food & Drug Administration (FDA) categorizing it as a Class I recall.50

Coverage for high-frequency chest compression vests may begin with a 3 month trial of device rental if the above criteria are met. At the end of the 3 month trial period, review of physician documentation regarding compliance with prescribed therapy and stable or improved respiratory status will be required. If it is determined that continued therapy is medically necessary, device rental may be extended until 13 months, at which time it may be purchased. Coverage will extend up to limitations and exclusions found in the member’s individual certificate.

Telecommunication or wireless transmission for high-frequency chest wall compression compliance is considered integral to the prescribed use of the device and not separately reimbursable.

Note: It is the Plan’s option to determine if the durable medical equipment (DME) item shall be rented or purchased. If the cost of renting the item is more than the cost to buy it, only the cost of the purchase is considered to be a covered expense. In either case (rent or purchase), total covered expenses shall not exceed the purchase price. In the event the Plan determines to purchase the DME, any amount paid as rent for such equipment will be credited toward the purchase price.

There is a limit of one approved air pulse generator per member. Additional vests may be covered if original vest no longer fits appropriately due to sizing changes (eg, child has outgrown vest).

Although these devices may be prescribed by a health care practitioner, these devices are also available without a prescription and may be obtained over-the-counter (OTC) and are therefore generally excluded in the certificate. In the absence of a certificate exclusion for OTC items, these devices are considered not medically necessary as defined in the member’s individual certificate. Please refer to the member’s individual certificate for the specific definition.

Humana members may NOT be eligible under the Plan for BiWaze Clear System (E1399), IPV (E0481) or Volara (E1399).
