Evidence Checklist: Pleural Effusion Residuals

Pulmonary function tests (PFTs) documenting restrictive impairmentCritical

Spirometry and DLCO documenting any residual restrictive ventilatory defect or reduced diffusing capacity caused by pleural fibrosis or trapped lung following a significant effusion.

Nexus opinion linking pleural effusion to service ("at least as likely as not")Critical

A medical opinion connecting the pleural effusion to an in-service condition such as chest trauma, pneumonia, empyema, or a service-connected systemic disease (heart failure, malignancy, or connective tissue disease).

Documentation of dyspnea and exercise limitation

Medical records documenting persistent dyspnea on exertion, reduced exercise tolerance, and activity limitations caused by the residual pleural disease.

Chest imaging documenting effusion history and residual pleural changesCritical

Chest X-ray or CT scan from the acute event and current imaging documenting residual pleural thickening, trapped lung, pleural calcification, or pleural fibrosis following resolution of the effusion.

Thoracentesis or pleural biopsy records

Pleural fluid analysis and any pleural biopsy pathology documenting the etiology of the effusion (exudate vs. transudate, infection, malignancy).

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.
