    Coverage Criteria

    Initial Request

    Covered for an initial request when all required administrative and clinical criteria are met and at least one qualifying treatment pathway applies.

    Required initial-request criteria

    • Administrative and clinical support: A complete prior authorization form, including all required documentation, is submitted; pulmonary function test (PFT) results support the diagnosis; the member has a covered diagnosis consistent with OHA guidelines for nebulizer use; and documentation shows that a metered-dose inhaler (MDI), with or without spacer or reservoir, was attempted or is contraindicated or insufficient.

      Covered diagnosis examples include COPD with airflow limitation confirmed by PFT, moderate to severe asthma, bronchiectasis, cystic fibrosis, tracheostomy with secretion management, or use of an inhaled drug requiring nebulization, such as treprostinil. Poor administration technique alone does not constitute treatment failure; provide education on proper product use, including a spacer and/or mask when appropriate.

    • ONE qualifying treatment pathway

      • Longstanding COPD pathway: The member has longstanding COPD with documented adherence to guideline-directed maintenance therapy consistent with current GOLD recommendations, and the treating provider documents that adding nebulizer therapy to established maintenance care is medically necessary to maintain disease stability or reduce the risk of emergency department visits or hospitalization.

        Qualifying requests may be approved for up to 12 months.

      • Covered nebulized-drug pathway: The nebulizer is requested to administer a covered inhaled drug with an FDA-approved nebulized formulation.

        Qualifying requests may be approved for up to 12 months.

    Renewal Request

    Covered for a renewal request when replacement quantities are within Table 1 guidelines or higher quantities are medically supported.

    ONE renewal pathway

    • Table 1 replacement pathway: Requested accessories, including tubing, masks, and filters, are within the OHA replacement frequency guidelines listed in Table 1.

      Apply the HCPCS-specific usual maximum replacement frequencies in Table 1.

    • Exception quantity pathway: The member's medical records clearly document and corroborate the medical appropriateness of current use with supply quantities greater than those described in Table 1.

      Higher quantities require clear supporting medical-record documentation.

    Step Therapy

    MDI Trial or Contraindication

    Document that a metered-dose inhaler (MDI), with or without a spacer or reservoir, was attempted or is contraindicated/insufficient for the member.

    • Poor administration technique alone does not constitute treatment failure.
    Prior Authorization

    Submit the Prior Authorization

    Complete and submit the PA request with the form and documentation needed to evaluate the diagnosis, pulmonary function testing, MDI history, and applicable treatment pathway.

    • A request lacking required clinical support does not meet criteria and may be denied.
    Documentation Required

    Pulmonary Function Testing Required

    Provide pulmonary function test (PFT) results supporting the diagnosis for which the nebulizer is requested.

    • PFT support may be relevant to diagnoses such as COPD, asthma, cystic fibrosis, or bronchiectasis.
    • If required PFT results are not submitted, the initial request may be denied as not meeting criteria.
    Documentation Required

    Diagnosis and MDI History

    Document a covered diagnosis consistent with OHA guidelines for nebulizer use and the member’s MDI history.

    • Covered diagnoses/pathways include COPD with airflow limitation confirmed by PFT, moderate to severe asthma, bronchiectasis, cystic fibrosis, tracheostomy with secretion management, or use of an inhaled drug requiring nebulization, such as treprostinil.
    • Document that an MDI with or without spacer/reservoir was attempted, or that it is contraindicated or insufficient.
    Documentation Required

    COPD Maintenance-Treatment Documentation

    For longstanding COPD, document adherence to guideline-directed maintenance therapy consistent with current GOLD recommendations and explain why adding nebulizer therapy to established maintenance care is medically necessary to maintain disease stability or reduce the risk of emergency department visits or hospitalization.

    • The explanation must be provided by the treating provider.
    • Failure to document qualifying maintenance therapy and medical necessity may result in denial.
    Documentation Required

    Administration-Technique Education

    Educate the member on proper product use and document the education and administration technique when a technique issue is identified.

    • Use a spacer and/or mask when appropriate.
    • Poor technique alone is not treatment failure; address technique before concluding that MDI therapy is inadequate.
    Documentation Required

    Support Additional Renewal Quantities

    When requested accessories exceed the replacement frequencies in Table 1, provide clear medical-record documentation corroborating the medical appropriateness of the current use and the greater quantities.

    • Documentation must support quantities of tubing, masks, filters, or other requested accessories beyond Table 1 limits.
    Denial Risk

    Incomplete Initial Request

    An initial request may be denied when the PA form is incomplete or required clinical support is missing.

    • Submit the complete PA form and all required documentation.
    • Include PFT results, diagnosis support, MDI trial or contraindication documentation, and any applicable treatment-pathway support.
    Denial Risk

    No Qualifying Treatment Pathway

    An initial request may be denied when the member does not meet a qualifying treatment pathway.

    • The qualifying pathways include documented longstanding COPD with guideline-directed maintenance therapy and provider-documented medical necessity for added nebulizer therapy, or administration of a covered inhaled drug with an FDA-approved nebulized formulation.
    • A covered diagnosis and required supporting documentation must also be present.
    Denial Risk

    Unsupported Excess Replacement Quantities

    A renewal request may be denied when quantities exceed Table 1 replacement frequencies without clear documentation supporting the medical appropriateness of the additional quantities.

    • Document the clinical need for excess tubing, mask, filter, or other accessory quantities in the member’s medical records.

    Renewal accessories are medically necessary when requested quantities are within Table 1 limits or higher quantities are supported by the member's medical record.

    ONE renewal accessory pathway

    • Within usual maximum replacement quantities: Requested accessories, including tubing, masks, and filters, are within the OHA replacement frequency guidelines listed in Table 1.

      Table 1 lists the usual maximum replacement frequency for each applicable HCPCS code.

    • Higher-quantity exception: For quantities above Table 1 limits, the member's medical records clearly document and corroborate the medical appropriateness of current use and the requested supply quantities.

      Without clear supporting documentation, higher replacement quantities do not meet medical-necessity criteria.
