Understanding the Complexity of Sleep Apnea Claims

Filing a claim for sleep apnea with the VA may seem straightforward due to the perception that a positive sleep study result automatically leads to a successful claim. However, the reality is more complex. Despite the increasing number of veterans submitting claims for sleep apnea, bolstered by the belief that these claims are easily approved, the actual approval rates tell a different story.

Sleep apnea claims are often misunderstood. A current diagnosis confirmed by a sleep study is a crucial first step, but it is far from the only requirement. The VA requires clear evidence that sleep apnea is connected to military service, not just the result of post-service lifestyle changes or other non-service-related factors such as non-service-connected weight gain, respiratory conditions, or other underlying health issues.

 

Sleep Apnea Symptoms

Obstructive Sleep Apnea (OSA) is a common disorder characterized by repeated episodes of partial or complete blockage of the airway during sleep. Here are some key symptoms associated with sleep apnea:

  • Snoring: Loud and frequent snoring can be a key indicator of sleep apnea. It occurs when air flows past relaxed tissues in the throat, causing the tissues to vibrate during breathing.

  • Episodes of Stopped Breathing During Sleep: Often reported by someone else, these episodes involve a complete or partial blockage of the upper airway, which is noticeable when the veteran temporarily stops breathing and then resumes often with a loud snort or choking sound.

  • Gasping for Air During Sleep: This symptom involves abrupt awakenings accompanied by gasping or choking, which is a reflexive response to re-establish breathing after an apnea event.

  • Daytime Fatigue and Sleepiness: Despite getting a full night's sleep, veterans might experience excessive daytime sleepiness, feeling unusually tired, and may fall asleep during activities that require attention, such as driving or working.

  • Morning Headaches: Often experienced upon waking, these headaches can result from the body's response to decreased oxygen levels and increased carbon dioxide levels in the blood during sleep.

  • Difficulty Concentrating: Sleep apnea can lead to poor brain oxygenation and fragmented sleep, which are associated with significant difficulties in maintaining concentration and alertness during the day.

  • Mood Changes: Irritability, depression, or mood swings may be noticed, likely due to poor sleep quality and chronic fatigue.

  • High Blood Pressure: Ongoing disruptions in breathing can cause blood pressure fluctuations, which, over time, may lead to consistently high blood pressure.

  • Night Sweats: Veterans might experience increased perspiration during sleep, which can be a response to the body's effort to re-establish breathing after apnea episodes.

  • Decreased Libido: The reduced energy levels and the physiological stress caused by chronic sleep interruptions can lead to a decrease in sexual drive.

  • Insomnia: Difficulty staying asleep can result from repeatedly waking up during the night due to apnea events.

 

 

Secondary Conditions Related to Sleep Apnea

 

For each of these secondary condition claims related to sleep apnea, it’s crucial to have comprehensive medical evidence. This evidence should include diagnostic test results, doctor’s opinions, and possibly a nexus letter that connects the primary service-connected condition with the development or worsening of sleep apnea. This helps establish a clear and direct link necessary for VA disability claims. Various service-connected conditions can aggravate sleep apnea, contributing to its severity or complications:

  • Sleep Apnea Secondary to Asthma:

    • Connection: Asthma can cause increased airway resistance and inflammation, which can worsen the symptoms of sleep apnea.

    • Claiming as Secondary: Veterans can claim sleep apnea as secondary to service-connected asthma by providing medical evidence showing that their asthma contributes to the development or exacerbation of sleep apnea, including details on airway resistance and inflammation.

  • Sleep Apnea Secondary to PTSD:

    • Connection: PTSD often leads to disrupted sleep patterns, nightmares, and anxiety, which can exacerbate sleep apnea. There is a noted high prevalence of sleep apnea among veterans with PTSD.

    • Claiming as Secondary: If sleep apnea develops or worsens as a result of managing PTSD, a veteran can claim it as a secondary condition. This requires medical documentation linking disrupted sleep patterns or heightened anxiety due to PTSD to the occurrence or worsening of sleep apnea.

  • Sleep Apnea Secondary to Sinusitis and Rhinitis:

    • Connection: These conditions can cause chronic nasal congestion and airway inflammation, leading to or worsening obstructive sleep apnea by physically blocking the airways.

    • Claiming as Secondary: Veterans should provide medical records and possibly a specialist’s statement showing how sinusitis or rhinitis has led to the development or aggravation of sleep apnea.

  • Sleep Apnea Secondary to Deviated Septum:

    • Connection: A deviated septum can restrict airflow during sleep, increasing the likelihood of airway collapse during throat muscle relaxation, thus contributing to sleep apnea.

    • Claiming as Secondary: A nexus letter from a healthcare provider that explains how the anatomical deviation of the nasal septum contributes to sleep apnea can support a claim.

  • Sleep Apnea Secondary to Chronic Respiratory Conditions:

    • Connection: Conditions like chronic obstructive pulmonary disease (COPD) or other chronic respiratory issues can impair respiratory function, reducing airway patency and increasing the work of breathing, which can exacerbate sleep apnea.

    • Claiming as Secondary: Veterans may claim sleep apnea as a secondary condition by presenting evidence from respiratory function tests and medical opinions linking chronic respiratory conditions to exacerbated sleep apnea.

  • Hypertension as Secondary to Sleep Apnea:

    • Connection: The low oxygen levels and high carbon dioxide levels during sleep apnea episodes can cause blood vessels to tighten and the heart to work harder, leading to elevated blood pressure.

    • Claiming as Secondary: If a veteran's service-connected sleep apnea leads to hypertension, it can be claimed as a secondary condition. Medical evidence would need to demonstrate that the hypertension is likely exacerbated by or a consequence of sleep apnea.

  • Diabetes Mellitus Secondary to Sleep Apnea:

    • Connection: Sleep apnea can increase insulin resistance due to the stress placed on the body by disrupted sleep and frequent awakenings, which can lead to higher blood sugar levels and, eventually, diabetes.

    • Claiming as Secondary: If diabetes develops as a result of managing a service-connected sleep apnea, it could be claimed as a secondary condition. A doctor would need to provide a nexus letter stating the diabetes is at least as likely as not caused by sleep apnea.

  • GERD Secondary to Sleep Apnea:

    • Connection: The effort to breathe against a closed airway in sleep apnea can increase intra-abdominal pressure, which can lead to acid reflux, manifesting as GERD.

    • Claiming as Secondary: GERD can be claimed as secondary to service-connected sleep apnea if medical documentation shows that the GERD symptoms are exacerbated by the mechanics of sleep apnea.

  • Depression Secondary to Sleep Apnea:

    • Connection: Chronic sleep disruption and the associated fatigue from sleep apnea can lead to psychological conditions such as depression due to decreased quality of life and chronic tiredness.

    • Claiming as Secondary: If a veteran develops depression linked to the lifestyle and health impact of service-connected sleep apnea, this could be claimed as a secondary condition. Supportive documentation would include a psychological evaluation and a medical opinion linking depression directly to sleep apnea.

 

VA Rating Schedule for Sleep Apnea

When the VA assesses a sleep apnea claim, the condition is rated under 38 CFR § 4.97, Diagnostic Code 6847, according to the severity of the condition and the level of treatment required:

  • 0% Rating: Assigned when there is a diagnosis of sleep apnea without significant symptoms or required continuous treatment. This rating recognizes the condition's presence but denotes it does not cause significant functional impairment under normal conditions.

  • 30% Rating: The required use of a CPAP machine elevates the rating to 30%. This reflects moderate severity and recognizes that the veteran needs a mechanical device to maintain nighttime breathing to prevent more severe complications.

  • 50% Rating: This rating is assigned if the veteran's condition results in chronic respiratory failure with carbon dioxide retention or requires the use of a tracheostomy. It indicates a severe level of sleep apnea that significantly impacts daily activities and health.

  • 100% Rating: The highest rating is given when sleep apnea causes chronic respiratory failure with carbon dioxide retention, requires a tracheostomy, or necessitates the veteran's use of a respirator. This rating reflects the life-threatening consequences of sleep apnea, requiring constant and intensive management.

 

Common Reasons for Sleep Apnea Claim Denials

For each of these secondary condition claims related to sleep apnea, detailed medical evidence and a clear nexus provided by a healthcare professional are crucial. This helps establish that the secondary conditions are indeed consequential to or aggravated by the primary service-connected condition of sleep apnea.

1. Bad and Inadequate Exams

  • Quality of VA Examinations: Occasionally, the examinations conducted by VA health professionals may not be thorough enough to correctly diagnose the severity of sleep apnea or to document its specific characteristics comprehensively. Incomplete or rushed examinations can fail to capture the full impact of the condition on the veteran’s health.

  • Failure of Duty to Assist: The VA is required to help claimants gather the necessary evidence to support their claims. This assistance might involve scheduling diagnostic tests, obtaining medical records, or providing access to specialists. When the VA does not fulfill this obligation adequately, essential evidence may be missing, leading to claim denial.

2. Lack of Medical Evidence

  • Formal Diagnosis: A formal diagnosis of sleep apnea, typically confirmed through a sleep study known as polysomnography, is essential. Without this, the VA may have insufficient evidence to recognize the condition as service-connected.

  • Continuous Treatment Records: It is crucial to demonstrate ongoing management and treatment of sleep apnea, such as consistent use of a CPAP machine. These records prove the persistence and severity of the condition, supporting the claim for disability benefits.

 

3. Failure to Establish a Service Connection

  • Direct Service Connection: The claim may be denied if there is no clear evidence showing that sleep apnea was diagnosed during or immediately after military service, or if there is no proof that an event or exposure during service precipitated or aggravated the sleep apnea.

  • Secondary Service Connection: Claims can also be denied if a veteran fails to adequately demonstrate how their sleep apnea is secondary to another service-connected condition. The VA requires clear medical evidence and rationale that links primary service-connected conditions to the onset or exacerbation of sleep apnea

 

4. Inadequate Nexus Statement

  • Vagueness or Lack of Specificity: A nexus letter that does not specifically state that sleep apnea is "as likely as not" caused by or connected to military service may not be persuasive enough. The letter must directly link the veteran’s service and their condition in clear, unequivocal terms.

5. Non-corroborative Statements:

  • If personal or buddy statements provided to support the claim do not align with medical evidence or lack details about how symptoms of sleep apnea were observed during and after military service, they may be deemed insufficient. These statements need to clearly support the claim by detailing the veteran’s symptoms and their impact. How to Write a Statement

6. Lack of Specificity:

  • General or Vague Statements that do not provide specific observations or instances of the veteran’s sleep apnea symptoms can weaken a claim. Detailed accounts that describe the observable impact of sleep apnea on the veteran’s daily life are crucial.

 

7. Misinterpretation of Symptoms

  • Attribution to Other Factors: Sometimes, the symptoms of sleep apnea, such as daytime fatigue or loud snoring, might be incorrectly attributed to less serious issues or lifestyle choices such as poor sleep habits or obesity. When symptoms are misinterpreted in this way, it can lead to the denial of the claim, as the VA may conclude that the condition is not service-connected or not severe enough to warrant compensation.

The Advocates Advice

Prepare for Rigorous Evaluation

Filing a claim for sleep apnea with the VA requires substantial evidence, thorough preparation, and an understanding of the legal standards applied by the VA. Veterans should approach this process with diligence, ensuring they have all necessary documentation and professional support to present the strongest possible claim. This level of preparation not only enhances the likelihood of a favorable outcome but also ensures that the claim process is as smooth and expedient as possible.

  • Be Prepared to Be Denied: This is a time to dig and focus on the evidence needed to win your case

  • Multiple Statements: They may need to gather multiple lay statements from people who can attest to their condition and how it has affected them over time. This includes statements from family, friends, and possibly colleagues who can discuss the impact of sleep apnea on their daily functioning.

  • Possible Multiple Exams: Be prepared to undergo multiple medical examinations, as the VA might require additional evidence or confirmatory tests to establish the severity and service connection of sleep apnea.

Subject: Claim for Sleep Apnea Aggravated by Service-Connected PTSD

To whom it may concern,

 

I am writing to file a claim for obstructive sleep apnea, a condition that has been severely aggravated by my service-connected Post-Traumatic Stress Disorder (PTSD), which originated from a violent assault during my service. My diagnosis of PTSD is well-documented and includes severe symptoms such as nightmares, night sweats, panic attacks, insomnia, and sleep paralysis.

The exacerbation of my sleep apnea is directly linked to these PTSD symptoms. My sleep is frequently interrupted by nightmares and panic attacks, which not only disturb my sleep but also lead to significant breathing cessation. These episodes of apnea contribute to extreme daytime fatigue and cognitive impairments, severely impacting my daily functioning and my ability to maintain employment. The stress and anxiety associated with PTSD further aggravate the muscle tension and physiological changes, worsening my sleep apnea.

 

Included with this letter is a nexus letter from Dr. [Doctor's Name], my treating physician. Dr. [Doctor's Name] has provided a detailed explanation of how the symptoms of my PTSD contribute to the severity of my sleep apnea. Additionally, lay statements from my wife and a longtime friend are enclosed, detailing their observations of my disrupted sleep patterns and the direct impact on my health and daily activities.

I respectfully request that this claim be processed with the understanding that my PTSD not only affects my mental health but also has a profound impact on my respiratory health through the aggravation of sleep apnea. I am willing to participate in further medical evaluations to substantiate this claim.

 

Thank you for your consideration and for the support in addressing these complications stemming from my dedicated service.

Subject: Claim for Sleep Apnea Secondary to Service-Connected Sinusitis and Rhinitis

 

To whom it may concern,

 

I am submitting this letter to advocate for my claim that my obstructive sleep apnea is a secondary condition to my service-connected sinusitis and rhinitis, which were caused by toxic exposures during my military service.

The persistent nasal congestion and anatomical blockages from my sinusitis and rhinitis significantly exacerbate my sleep apnea, leading to frequent nightly disruptions and severe daytime fatigue. This condition has degraded my quality of life, impairing my ability to concentrate and perform my job functions effectively. The inflammation and mucus accumulation not only narrow my airways during sleep, causing repeated interruptions in breathing but also result in chronic tiredness that affects my daily activities and job performance.

Included is a nexus letter from Dr. [Doctor's Name], my otolaryngologist, detailing how the chronic inflammation associated with sinusitis and rhinitis directly contributes to the exacerbation of sleep apnea. Also enclosed are statements from my current employer and colleagues who have observed the decline in my work performance and overall alertness, directly correlating with my sleep-related issues.

I trust that this evidence will adequately support the claim that my sleep apnea while debilitating on its own, is significantly intensified by my sinus and nasal conditions, both of which are service-connected. I am prepared to provide additional information or undergo further evaluations as necessary.

Thank you for your attention to this critical matter and for your continued support of veterans.

 

 

Respectfully,
