Drug-Induced Pulmonary Pneumonitis/Fibrosis — VA Disability Rating Criteria (DC 6829)
Diagnostic Code 6829 · 38 CFR §4.97
What Is It?
Drug-induced pulmonary pneumonitis or fibrosis occurs when medications cause inflammation or scarring in the lungs. Veterans may develop this as a side effect of medications prescribed during or after service, including certain antibiotics, chemotherapy agents, cardiac medications (amiodarone), or anti-inflammatory drugs. If the causative medication was prescribed for a service-connected condition, the lung damage itself is service-connectable on a secondary basis.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Severe pulmonary fibrosis from drug toxicity causing respiratory failure or requiring continuous oxygen therapy. |
| 60% | Significant irreversible lung damage from drug exposure with substantially reduced PFT values and exercise intolerance. |
| 30% | Moderate residual pulmonary impairment persisting after the causative drug was stopped. PFTs show meaningful reduction in lung function. |
| 10% | Mild residual lung changes after drug discontinuation with minimal PFT impairment. FVC or DLCO mildly reduced. |
Evidence Needed
Medical records showing the medication prescribed and its timeline. Documentation linking the medication to the lung damage (pulmonologist opinion). PFTs before and after drug exposure if available. Evidence that the medication was prescribed for a service-connected condition (for secondary claims). Current PFTs and imaging.
C&P Exam Tips
Clearly identify which medication caused the lung damage and why it was prescribed. Bring a timeline showing medication start, symptom onset, and current status. Ensure current PFTs include DLCO.
How to File
File as a secondary condition to whatever service-connected condition required the causative medication. Include the prescribing records, medical evidence linking the drug to your lung damage, and current PFT results showing impairment.
Common Mistakes
Not establishing the causal chain from service-connected condition to medication to lung damage. Failing to get a pulmonologist opinion on causation. Not documenting that the lung damage persists after drug discontinuation.
Frequently Asked Questions
Which medications commonly cause lung damage?
Common culprits include amiodarone (heart medication), methotrexate (autoimmune conditions), bleomycin (chemotherapy), nitrofurantoin (antibiotic), and certain biologics. If you developed respiratory symptoms while on any long-term medication, discuss the connection with your doctor.
Can I claim this if the medication was prescribed by VA doctors?
Yes. If VA-prescribed medication for a service-connected condition caused lung damage, that is a valid secondary service connection claim. You may also have a 1151 claim if the prescribing was negligent, though that is a separate legal theory.
