Tracheal Stenosis

DC 6520Respiratory38 CFR 4.97, DC 6520

A narrowing of the trachea (windpipe) that restricts airflow and makes breathing difficult. Can result from prolonged intubation during service-related medical treatment, inhalation injuries, or trauma. The VA rates tracheal stenosis based on the degree of airflow obstruction and need for medical intervention.

How the VA rates this condition

The VA rates this condition based on objective clinical measurements and test results. The examiner will use standardized tests or lab values to determine the severity of your condition rather than relying primarily on subjective symptom reports.

Diagnostic code

DC 6520

Rating range

10% – 100%

Rating levels

Rating criteria are defined in 38 CFR 4.97, DC 6520. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

You have severe tracheal stenosis requiring tracheostomy, continuous positive airway pressure, or causing respiratory failure. You may be unable to perform routine activities.

What the VA looks for

Severe tracheal narrowing or near-complete obstruction
FEV-1 less than 40% predicted
Tracheostomy in place
Episodes of acute respiratory failure
Continuous positive airway pressure required

Common Pitfalls

⚠Not obtaining bronchoscopy or CT airway imaging — standard PFTs may underestimate the degree of fixed upper airway obstruction. Direct visualization provides the strongest evidence.
⚠Not connecting stenosis to in-service intubation or trauma — obtain medical records showing the intubation event, inhalation injury, or neck/chest trauma that caused the narrowing.
⚠Not documenting the impact on daily activities — describe how breathing restriction limits your work capacity, exercise tolerance, and quality of life.
