DESCRIPTION OF PROCEDURE OR SERVICE:

Individuals with high-level vertebrae C1-C3 spinal cord injuries typically experience respiratory muscle paralysis leading to chronic ventilatory insufficiency. The standard therapy for these patients is chronic mechanical ventilation via tracheostomy.

Non-invasive ventilation (NIV) such as positive ventilation or bilevel positive airway pressure is currently the first line treatment for amyotrophic lateral sclerosis (ALS) patients experiencing symptoms of respiratory insufficiency. Eventually, ALS affects the respiratory muscles so severely that bulbar paresis is combined with severe expiratory and inspiratory muscle weakness. There is a significant risk of impending respiratory failure or death and invasive ventilation becomes the only option for survival.

Diaphragmatic/phrenic nerve stimulation, is an alternative to mechanical ventilation for a select subgroup of individuals. Diaphragmatic/phrenic nerve stimulation, also referred to phrenic pacing, phrenic nerve stimulation, diaphragm pacing, or electrophrenic respiration, is the electrical stimulation of the diaphragm via the phrenic nerve, the major nerve supply to the diaphragm that controls breathing. Individuals with partial or complete respiratory insufficiency who have an intact phrenic nerve and diaphragm may be eligible for diaphragmatic/phrenic nerve stimulation. The individual should be alert, mentally competent, motivated and able to complete the training and rehabilitation needed for a successful outcome. Prior to implantation patients may undergo diaphragm electromyography, pulmonary function studies and/or polysomnography (i.e., sleep study). Common indications include individuals with high quadriplegia (spinal cord injury) at or above C-3, chronic central alveolar hypoventilation syndrome (CCHS), and amyotrophic lateral sclerosis (ALS).

KEY POINTS:

Literature review completed through July 10, 2024.

SUMMARY OF EVIDENCE:

Diaphragmatic pacing is a therapy intended for individuals with ventilatory failure due to bilateral diaphragm paresis or paralysis. This is aimed at giving these individuals an opportunity to become free or delay the need for invasive mechanical ventilation, improving the quality of life. Diaphragm pacing is a relatively rare procedure, so individuals should be evaluated at centers of expertise. 

PRACTICE GUIDELINES AND POSITION STATEMENTS:

AMERICAN ACADEMY OF NEUROLOGY (AAN)

In 2009 (reaffirmed in 2023), the American Academy of Neurology (AAN) issued a practice parameter update on the care of the patient with amyotrophic lateral sclerosis (ALS): drug, nutritional and respiratory therapies an evidence based review. The recommendations in this practice parameter update does not mention diaphragmatic/phrenic nerve stimulation or diaphragm pacing as a treatment.

AMERICAN THORACIC SOCIETY (ATS)

In 2010, the American Thoracic Society clinical policy statement on congenital central hypoventilation syndrome in their discussion of the diagnosis and management of children with congenital central hypoventilation syndrome (CCHS) which states: diaphragm pacers can be used for daytime support of ambulatory children who require full-time ventilator support, in combination with positive pressure ventilation at night.

U.S. Preventive Services Task Force Recommendations

Not applicable.

Medical Policy Group, July 2024 (6): Updates to Key Points and References.

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.

This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.

The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.

As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.

The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:

1. The technology must have final approval from the appropriate government regulatory bodies;

2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;

3. The technology must improve the net health outcome;

4. The technology must be as beneficial as any established alternatives;

5. The improvement must be attainable outside the investigational setting.

Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:

1. In accordance with generally accepted standards of medical practice; and

2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and

3. Not primarily for the convenience of the patient, physician or other health care provider; and

4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
