Ask the Attorney Series: Why Sleep Apnea Claims Get Denied
Sleep apnea is one of the most frequently discussed conditions in the VA disability space—but having a diagnosis of obstructive sleep apnea (OSA) and using a CPAP does not automatically establish service connection.
So why do sleep apnea claims get denied?
In this episode of our Ask the Attorney Series, we break down some of the common medical and evidentiary problems that arise in VA sleep apnea claims, including direct and secondary service connection, medical nexus evidence, risk factors, and the theories frequently presented to VA.
In This Video:
- Common reasons VA sleep apnea claims are denied
- Why a sleep apnea diagnosis alone does not establish service connection
- Direct vs. secondary service connection for sleep apnea
- The importance of establishing an accurate timeline of symptoms and diagnosis
- The role of a sleep study in documenting obstructive sleep apnea
- Sleep apnea claimed secondary to other service-connected conditions
- PTSD and obstructive sleep apnea claims
- The obesity intermediate-step theory
- Rhinitis, sinusitis, and other respiratory conditions in sleep apnea claims
- Why association does not necessarily establish medical causation
- The importance of considering established OSA risk factors
- What medical nexus evidence should address
- Common problems with unfavorable and inadequate medical opinions
- How C&P examinations may affect a sleep apnea claim
- Why conflicting medical evidence should be addressed rather than ignored
Secondary Service Connection Can Be Complicated
Many sleep apnea claims involve a theory that OSA developed because of—or was aggravated by—another service-connected disability.
But simply having two medical conditions at the same time does not necessarily establish that one caused the other.
A meaningful medical analysis should consider the veteran's individual medical history, chronology, relevant risk factors, proposed physiological mechanism, and applicable medical literature.
Depending on the theory being presented, the analysis may also need to distinguish between causation and aggravation, which are separate medical questions.
What About PTSD and Sleep Apnea?
Veterans frequently ask whether PTSD can cause obstructive sleep apnea.
Research may identify associations between certain populations or medical conditions, but an association does not automatically establish causation in an individual veteran.
The relevant question is not simply whether literature exists mentioning PTSD and sleep apnea. The medical analysis should address whether the proposed relationship is medically supportable in the specific veteran's case.
The Obesity Intermediate-Step Theory
Obesity may also become relevant in certain secondary service-connection theories.
For example, a veteran may contend that a service-connected disability contributed to obesity, which then played a role in the development or aggravation of obstructive sleep apnea.
This is a multi-step analysis. Each part of the proposed relationship should be supported by the veteran's medical history and appropriate medical evidence rather than assumed simply because obesity and OSA coexist.
Key Takeaway
A diagnosis of obstructive sleep apnea and a CPAP prescription establish important facts about the veteran's current condition—but they do not, by themselves, answer the service-connection question.
When a sleep apnea claim is denied, identifying why it was denied is critical.
Was there insufficient evidence of an in-service event or symptoms? Was the medical nexus unsupported? Was a secondary theory inadequately addressed? Was causation considered but aggravation overlooked? Were significant risk factors or conflicting evidence identified?
Understanding the specific issue can help clarify what medical or evidentiary question actually remains unresolved.
Every veteran's medical history is different, and medical opinions should be based on the individual evidence rather than a generalized assumption that a particular diagnosis automatically causes—or cannot cause—sleep apnea.
