A pre-existing history of insomnia does not automatically disqualify you from VA disability benefits. You may still qualify if the evidence shows that your military service worsened the condition. These claims often require medical and service records that document how your symptoms changed over time.
This guide explains how the VA evaluates pre-existing conditions, what evidence may help establish aggravation, and how to show that your insomnia became worse during military service.
How Does The VA Rate Insomnia?
VA does not list insomnia under a separate diagnostic code. Instead, service-connected insomnia is generally evaluated under the General Rating Formula for Mental Disorders. The VA considers the frequency, severity, and duration of symptoms and their effect on occupational and social functioning.
Under the current schedule, insomnia may receive a 0%, 10%, 30%, 50%, 70%, or 100% rating. Chronic sleep impairment appears in the 30% criteria, but it does not automatically result in a 30% rating. The VA considers the veteran’s overall impairment.
The VA proposed a five-domain mental health framework, but it has not taken effect. The current schedule still applies. To avoid pyramiding, the VA generally will not compensate the same insomnia symptoms twice when they overlap with another mental health condition. Veterans with separately rated conditions can use a VA disability calculator to estimate their combined rating.
The Principle of "Aggravation"
At MEPS, recruits complete a medical questionnaire and examination, and prior conditions should be disclosed. Under the presumption of soundness, the VA generally assumes that you entered military service without a pre-existing condition unless it was noted on your entrance examination. If insomnia was recorded at entry, the question becomes whether your military service made it worse. If the condition was not recorded, the VA must meet a higher standard to establish that it existed before service and was not aggravated by service.
A pre-existing condition may be considered aggravated when it became more severe during service, unless the evidence shows that the increase resulted from its natural progression. You do not have to prove that military service first caused the insomnia. Instead, the evidence should show that symptoms worsened during service, such as after night operations, deployment-related stress, or a service-related injury. The VA addressed this standard in a 2020 proposed rule, but the current standard remains in 38 C.F.R. § 3.306.
How Does the VA Evaluate Worsening Sleep Conditions?
To determine whether military service aggravated pre-existing insomnia, the VA reviews evidence showing how the condition presented before, during, and after service. Entrance examinations and pre-service treatment records may help establish its earlier severity. Service records, medical records, and statements from the veteran or others may then document changes that occurred during service.
The key question is whether the insomnia increased in severity during service. Under 38 C.F.R. § 3.306, a pre-existing condition is generally considered aggravated when it worsens during service, unless the increase resulted from the condition’s natural progression. A medical opinion may help distinguish between these possibilities.
The VA considers medical and lay evidence. When the existing evidence is insufficient to decide a qualifying claim, the VA may provide an examination or obtain a medical opinion. A nexus letter or supporting opinion may therefore come from a VA examiner or a private medical provider.
What Considerations Should You Be Aware of for Your VA Claim?
When seeking benefits for aggravated insomnia, it is important to distinguish between a condition that worsened during service and one that was later aggravated by another service-connected disability. The VA applies different rules to these claims, particularly when determining the degree of worsening that may be compensated.
The "Subtraction" Principle
Under 38 C.F.R. § 3.322, compensation for a pre-existing condition aggravated during service generally reflects only the degree of disability beyond what existed at entry. The VA deducts the ascertainable entrance-level evaluation from the current evaluation.
For example, if your current insomnia warrants a 50% evaluation and its severity at entry was equivalent to 10%, the compensable degree would generally be 40%. However, no deduction is made if the current disability is rated 100% or if the degree of disability at entry cannot be determined under the rating schedule.
One important rule can affect the final rating. Before making a deduction, the VA must establish that insomnia existed at entry. It must also determine its severity under the rating schedule. If the entrance-level severity cannot be determined, no deduction is made. Reviewing early medical and entrance records can help clarify whether a deduction applies.
Secondary Conditions and Lay Evidence
Other service-connected conditions may also contribute to worsening insomnia. For example, chronic pain from a shoulder injury or persistent ringing caused by tinnitus may make it harder to fall asleep or remain asleep. If a service-connected condition aggravates pre-existing insomnia, the veteran may be able to pursue benefits for insomnia on a secondary basis.
Lay evidence can also help document how the condition changed over time. Statements from family members, friends, or fellow service members who knew the veteran before and after service may describe noticeable changes in sleep patterns, mood, fatigue, or daily functioning. These firsthand observations can provide useful context when earlier medical records do not fully capture the progression of the insomnia.
Next Steps, When You Are Ready
Building an aggravation claim requires evidence showing how your insomnia changed during military service. Consider these steps:
- Request your entrance examination and available pre-service medical records.
- Gather current records documenting your diagnosis and symptoms.
- Ask whether a medical opinion or nexus letter could help explain why the worsening exceeded the condition’s natural progression.
If the VA previously denied your claim because your insomnia existed before service, you may still have options for challenging the decision. Our team can review the available evidence, explain the appeals process, and help you determine an appropriate next step. Contact us to discuss your claim.
