Delirium — VA Disability Rating Criteria (DC 9300)
Diagnostic Code 9300 · 38 CFR §4.130
What Is It?
Delirium is an acute disturbance in attention, awareness, and cognition that develops over a short period and fluctuates in severity. It is caused by an underlying medical condition, substance intoxication or withdrawal, medication effects, or multiple combined factors. For veterans, delirium may occur as a result of traumatic brain injury, toxic exposures, combat injuries requiring surgery, or medication reactions during service. While delirium itself is typically temporary, it can cause lasting cognitive impairment — particularly in cases of prolonged or repeated episodes. When residual cognitive or psychological symptoms persist, they may be rated under DC 9300 using the General Rating Formula for Mental Disorders.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Total occupational and social impairment with severe residual cognitive deficits, disorientation, inability to perform daily activities, and need for constant supervision. |
| 70% | Deficiencies in most areas due to significant residual cognitive impairment. May include disorientation, near-continuous confusion or anxiety, and inability to function independently. |
| 50% | Reduced reliability due to persistent cognitive deficits, difficulty understanding complex commands, impaired judgment, and difficulty maintaining relationships. |
| 30% | Occasional decrease in work efficiency due to residual cognitive impairment, mild memory loss, difficulty concentrating, or anxiety about recurrence. |
| 10% | Mild residual cognitive symptoms that decrease work efficiency only during significant stress. |
| 0% | History of delirium but no residual symptoms affecting functioning. |
Evidence Needed
Medical records documenting the delirium episode during service or caused by a service-connected condition are essential. These may include hospital records showing altered mental status, ICU records, or surgical records noting post-operative delirium. Follow-up neuropsychological testing showing residual cognitive impairment strengthens the claim. A nexus opinion connecting the delirium to service or a service-connected condition is required. Buddy statements from family describing cognitive or behavioral changes after the episode add context.
C&P Exam Tips
If your claim is based on residual symptoms after a delirium episode, describe the current cognitive difficulties you experience: memory problems, difficulty concentrating, confusion, difficulty with complex tasks. Explain when the delirium occurred, what caused it, and how your functioning has been different since. If you underwent neuropsychological testing, reference those results. Describe the practical impact: Can you manage finances? Follow multi-step instructions? Remember appointments?
How to File
File on VA Form 21-526EZ. Include hospital records documenting the delirium episode and its cause. Submit follow-up evaluations showing residual impairment. A nexus letter connecting the episode to a service event or condition is important. If filing as secondary to a service-connected condition (such as TBI or medication side effects), include the primary claim number.
Common Mistakes
The main mistake is not recognizing that a delirium episode during service left lasting cognitive effects. Many veterans attribute persistent cognitive problems to aging or other causes without connecting them to a documented episode. Not obtaining the original hospitalization records is a common oversight.
Frequently Asked Questions
Can I file for delirium that happened during service?
Yes, if the episode left residual cognitive or psychological impairment. The rating is based on your current symptoms, not the acute episode itself. You need documentation of the original episode and evidence of persistent effects.
How is delirium different from TBI for VA purposes?
Delirium is an acute confused state caused by a medical condition, while TBI is caused by physical trauma to the head. They can overlap — a TBI can cause delirium. If both apply, work with your VSO to determine the best rating approach to avoid pyramiding.
