Coverage Criteria for ENB
Covered indications
Electromagnetic Navigation Bronchoscopy is considered medically necessary when ANY one of the following is met:
Covered Indications
- Indication A: Suspicious pulmonary nodule that is deemed inaccessible by standard methods (e.g. peripheral nodule) or when standard methods have failed
Supports use for peripheral nodules or after failed standard methods
- Indication B: Highly suspicious solitary pulmonary nodule in an individual who poses an unacceptable risk for a more invasive diagnostic procedure (e.g., bullous lung disease, diffuse emphysema)
Used when less invasive options are needed due to procedural risk
- Indication C: Identified lung lesion(s) in an individual with co-existing cancer where determination of the lung lesion will impact staging and treatment plan
Staging impact guides coverage
- Indication D: Placement of fiducial markers in individuals who are not candidates for surgical intervention and have elected to undergo radiation therapy
For marker placement to facilitate radiation treatment
Clinical records may be requested to verify medical necessity
Use of electromagnetic navigation bronchoscopy (ENB) for any indication other than the specific covered indications listed in this policy is considered investigational and is not covered.
This medical policy is provided for informational purposes only and is not an authorization, certification, explanation of benefits, or a contract. Coverage and benefits are determined by the member’s group contract and subscriber certificate that are in effect at the time services are rendered; providers must verify benefits and obtain any required authorizations based on the member’s contract before performing services.
Any indication for ENB that is not explicitly listed as medically necessary in this policy is categorized as investigational and therefore not covered.

Provider Actions and Requirements
Prior authorization and applicable codes
Coverage is provided when the medical necessity criteria in this policy are met. Applicable procedure codes are listed in the Billing/Coding section and inclusion of a code does not guarantee reimbursement; codes may require review when medical records are requested for medical necessity determination.
Verify benefits and obtain required authorizations
Verify member benefits and obtain any required authorizations per the member's group contract and subscriber certificate before performing services. This policy itself is informational and is not an authorization or contract.
- Benefits and eligibility are determined by the group contract and subscriber certificate in effect at the time services are rendered
- Obtain prior authorization when required by the member's plan
Use standard methods first when feasible
Attempt standard diagnostic methods first (for example, flexible bronchoscopy with or without endobronchial ultrasound). If standard methods are inadequate or have failed, document the reason(s) prior to considering ENB.
- Standard methods examples: flexible bronchoscopy ± endobronchial ultrasound
- Document why standard methods are inaccessible, inadequate, or have failed
Provide clinical documentation to support medical necessity
Include clinical documentation demonstrating the individual meets the medical necessity criteria when medical records are requested. Useful documentation can include procedure notes, imaging reports, and explanations of prior failed or infeasible standard methods.
- Provide documentation of indication (e.g., peripheral nodule inaccessible by standard methods)
- Include records showing why alternative diagnostics are contraindicated or have failed
Informational policy—verify benefits and eligibility
This policy is provided for informational purposes only and is not an authorization, certification, explanation of benefits, or contract. Providers must verify benefits and eligibility with the member's plan prior to service delivery.
- Policy does not replace benefits/eligibility verification
- Verify coverage per the member's group contract and subscriber certificate
Documentation may be requested and lack of support can trigger denial
BCBSNC may request medical records to determine medical necessity; failure to supply adequate supporting documentation (including requested medical records) could result in denial of the service.
- When records are requested, letters alone are insufficient unless they contain all specific information needed for medical necessity determination
- Lack of requested documentation may trigger claim denial
Confirm benefits/eligibility before applying medical policy
Benefits and eligibility are determined before medical guidelines and payment rules are applied; services that are not a covered benefit under the member's contract may be denied even if they meet policy criteria.
- Confirm the service is a covered benefit under the member's group contract and subscriber certificate before scheduling
- Denial can occur if the service is not covered by the member's plan
Background
Electromagnetic navigation bronchoscopy (ENB) augments standard bronchoscopy by using a three-dimensional CT-based roadmap and electromagnetic tracking to provide real-time positional feedback, enabling navigation of a steerable probe to more distal or peripheral lung regions for biopsy or placement of fiducial markers.
