Monitor payer policy activity
Medical policy governing coverage of lung volume reduction surgery (LVRS) for treatment of emphysema for Blue Cross Blue Shield of North Carolina members; describes clinical criteria for when LVRS is considered medically necessary and when it is investigational.
No material clinical or coverage changes in this revision.
Coverage Criteria for Lung Volume Reduction Surgery
Initial eligibility criteria
Lung volume reduction surgery is medically necessary when ALL of the following criteria are met:
FEV1 age-specific condition from policy
NETT physiologic refinements
Additional physiologic criteria (from NETT) that may further refine candidate selection:
NETT trial criteria
Patients who do not meet ALL of the medical necessity criteria listed for lung volume reduction surgery are not eligible for coverage. Key disqualifying situations include: non–predominantly upper‑lobe emphysema or lack of hyperinflation/heterogeneity, FEV1 outside the age‑specified thresholds, age ≥75 years, inability to participate in a vigorous pulmonary rehabilitation program, ongoing cigarette smoking (not abstinent for at least 4 months), unacceptable nutritional status (outside 70–130% of ideal body weight), or the presence of major comorbidities that significantly increase operative risk. When documentation is insufficient to confirm that all required criteria are met, the procedure may be treated as investigational and denied.
Lung volume reduction surgery is considered investigational and not covered when the medical necessity criteria specified in this policy are not met. Blue Cross Blue Shield of North Carolina does not cover services designated as investigational.

- Provide complete medical records when requested to support medical necessity determinations.
- Letters of support/explanation alone are insufficient unless they contain all required clinical details specified by BCBSNC.
Investigational — not covered when medical necessity criteria are not met
Lung volume reduction surgery is considered investigational and is not covered when the medical necessity criteria in this policy are not met.
- If the patient does not meet ALL listed medical necessity criteria (e.g., non–upper-lobe disease, insufficient FEV1, age ≥75 years, active smoking, inability to participate in rehab, poor nutrition, major comorbidities), LVRS is investigational and not covered.
Background
Emphysema is an anatomic subtype of chronic obstructive pulmonary disease characterized by destruction of alveolar walls and enlargement of airspaces. Lung volume reduction surgery (LVRS) removes portions of emphysematous lung (commonly bilateral upper lobes) to reduce hyperinflation and improve respiratory mechanics, ventilation–perfusion matching, and cardiac filling; the procedure carries significant risks, including operative mortality, prolonged ventilation, infection, arrhythmia, and persistent air leak.

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.
