Coverage Criteria

Mechanical Insufflation-Exsufflation (E0482) — Covered when ALL of the following are met

Covered when ALL of the following are met

MIE coverage criteria: 1. Presence of neuromuscular or chest wall disease (eg, amyotrophic lateral sclerosis, congenital muscular dystrophies, Duchenne muscular dystrophy, multiple sclerosis, post-poliomyelitis, spinal cord injury, spinal muscle atrophy).

MIE coverage criteria: 2. The condition causes a significant impairment of chest wall and/or diaphragmatic movement resulting in an inability to clear retained secretions.

MIE coverage criteria: 3. Inadequate response or intolerance to chest percussion and postural drainage.

Failure, intolerance, or contraindication to conventional airway clearance is required before considering device use.

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

High-Frequency Chest Compression / HFCWO (E0483) — Covered when ANY of the following are met

Covered when ANY of the following are met

HFCWO coverage criteria: 1. Cystic fibrosis when there is failure, intolerance, or contraindication to home chest physiotherapy, or it cannot be provided.

HFCWO coverage criteria: 2. Bronchiectasis confirmed by high-resolution, spiral, or standard CT scan characterized by either: a) daily productive cough for at least 6 continuous months; OR b) frequent (eg, >2/year) exacerbations requiring antibiotic therapy.

Either subcriterion (a) or (b) under criterion 2 satisfies this item for coverage of E0483.

CriterionDaily productive cough for at least 6 continuous months.

ContextApplies to confirmed bronchiectasis by CT (high-resolution, spiral, or standard).

Policy sourceII.A.2.a in HFCWO coverage criteria: documentation of daily productive cough ≥6 months required for coverage.

CriterionMore than 2 exacerbations per year requiring antibiotic therapy (frequent exacerbations).

ContextCounts as alternate bronchiectasis criterion for HFCWO coverage when confirmed by CT.

Provider Actions & Documentation Requirements

Prior Authorization

Prior authorization required for E0482 and E0483

Prior authorization/medical necessity documentation is required demonstrating the member meets the policy's clinical criteria for the requested device (E0482 or E0483). Requests for indications not supported by the policy are not reimbursable.

Step Therapy

Conservative therapy trial required

A trial and documentation of failure, intolerance, or contraindication to conventional airway clearance (for example, chest percussion and postural drainage) must be present before mechanical insufflation-exsufflation or HFCWO will be considered.

Documentation Required

CMN required for continued HFCWO rental

For continued HFCWO use after the initial trial/rental period, include a Certificate of Medical Necessity (CMN) that attests to device effectiveness during the trial and prior rental periods, documents any change in duration or frequency of therapy, and recommends additional rental or purchase as applicable.

Attestation to effectiveness during the trial and every previous rental period
Specification of any change in duration or frequency of therapy, if applicable
Recommendation for additional rental or for purchase

Denial Risk

Non-listed indications for MIE devices are not covered

Requests for mechanical insufflation-exsufflation devices for indications not listed in the policy (i.e., indications other than the specified neuromuscular or chest wall diseases with resulting impairment) are not covered or reimbursable and will be denied without supporting documentation meeting policy criteria.

Background

Retention of airway secretions results from either increased production or impaired clearance and contributes to clinical morbidity when secretions cannot be effectively mobilized and expelled. Conditions that commonly lead to secretion retention include obstructive and inflammatory lung diseases such as asthma and chronic obstructive pulmonary disease, congenital or acquired mucociliary disorders, cystic fibrosis, and neuromuscular or chest wall disorders that weaken cough and diaphragmatic or chest wall movement. Patients with such impairments have higher rates of complications related to retained secretions; conventional chest physiotherapy (eg, percussion and postural drainage) is effective but resource-intensive, and airway clearance devices are used to assist mobilization and expectoration when conservative measures are inadequate or impractical.

Definitions

inv-14: High Frequency Chest Compression Device

DefinitionAn inflatable vest connected to an air-pulse generator that rapidly inflates and deflates to compress and release the chest wall (up to ~20 times per second).

ComponentsInflatable vest plus tubing connected to a small air-pulse generator.

MechanismGenerator produces rapid air pulses to inflate/deflate vest, producing chest wall compression and release to mobilize secretions.

inv-15: Mechanical Insufflation-Exsufflation Device

DefinitionA facemask-based device that insufflates the lungs and then rapidly evacuates air to facilitate expulsion of secretions.

InterfaceFacemask covering nose and mouth to deliver positive insufflation and rapid exsufflation cycles.

MechanismAlternating insufflation and rapid evacuation of air to augment cough and clear retained airway secretions.
