    OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.

    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.

    MIE coverage criteria: 4. No bullous emphysema, pneumomediastinum, or pneumothorax.

    All four criteria must be met for coverage of E0482.

    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.

    CareSource does not consider concurrent use of both airway clearance systems to be medically necessary. Specifically, it is not reasonable and necessary for a member to use both a high-frequency chest compression (HFCWO) device and a mechanical insufflation-exsufflation (MIE) device at the same time, and requests proposing simultaneous use will not meet coverage criteria. Additionally, the Volara device is not approved for outpatient use and therefore is not an acceptable option for outpatient coverage.

    Chronic bronchitis and chronic obstructive pulmonary disease (COPD) without a confirmed diagnosis of bronchiectasis do not meet criteria for HFCWO coverage. Coverage for HFCWO requires either cystic fibrosis with failure/intolerance/contraindication to home chest physiotherapy or a CT-confirmed diagnosis of bronchiectasis meeting the policy’s symptom or exacerbation thresholds; COPD or chronic bronchitis alone is explicitly excluded when bronchiectasis is not documented.

    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

    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.

    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

    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.

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