Question:
Jim,
i recently got a rating for copd at 30 percent,not knowing that i could claim for sleep apnia as it can aggravate the copd condition,do i need a nexus to establish that the presence of sleep apnia in connection with copd should be considered as separate and rated separately?.What im having a hard time understanding is that i have three sleep studies all stating and documented in my va medical records.its there(obstructive sleep apnia),theres no doubt,but my service rep at american leigion is telling me i should get a nexus from a doc since theres nothing in my medical records from the military service that i ever had sleep apnia while on active duty.,on one hand im thinking im hearing that my sleep apnia should be rated as secondary to the copd/emphasema.the only thing a nexus will do is establish that i had it in the navy which theres no doc i know on the planet that will make that statement.(do you know one)the other belief i have is that i see no reason to put alot of energy to get a nexus from a doc for the sleep apnia being secondary because its already well established .(i think i might also be misguided.)i(im lost) can you provide any guidance?????
Answer:
I hope I can shed a little light on a complex question.
What you're trying to do is have your sleep apnea rated as service connected secondary to the already SC COPD.
Let's discuss how these things work by using another condition that may be easier to understand.
Adult onset diabetes (DMII) is a common problem among vets and civilians. As we age our bodies don't produce or utilize out natural insulin as well as when we were younger. In the veteran population, it's recognized that exposure to Agent Orange statistically increases the chances that one will develop DMII. DMII is on the "presumptive list" of conditions that are rated as service connected for most Vietnam veterans.
DMII is well known to cause or contribute to other conditions. This is so well documented that as soon as you're diagnosed with DMII you'll probably get a talk about the issues associated with it if you don't control it. The first thing you'll hear of is how DMII contributes to vascular (blood vessel) disease and can lead to heart attack, stroke, peripheral artery disease and erectile dysfunction.
If you are diagnosed with DMII and subsequently develop coronary artery (heart) disease, you may file the heart condition as being service connected secondary to the DMII. One thing connects to the other...there is a clinical nexus.
You have a diagnosis of Chronic Obstructive Pulmonary Disease or COPD. That means you have difficulty breathing due to damage that was caused to your lungs at some time. That you have a rating of 30% for that means that it is ceded by the VA to have been caused or aggravated by your military service.
Now you need to prove that the sleep apnea is a separate condition caused or aggravated by the COPD. A letter from a physician would be a big help. That letter would have to state very clearly that in the doctor's opinion, having examined your medical records, he or she believes it is more likely than not that your sleep apnea is caused by or aggravated by your COPD.
That seems a reasonable assumption. The next thing to do is to search the medical literature to see if anything is there to support that. On the Google search engine when we use the search words <sleep apnea COPD> we get over 400,000 hits.
We first read, "Sleep is the period of greatest physiologic disturbance in chronic obstructive pulmonary disease (COPD) and the time of greatest danger to these individuals." But this article doesn't conclude that any relationship exists.

In another article the author says, "In conclusion, COPD without daytime hypoxemia was not a risk factor for sleep apnea or nocturnal hypoventilation in this study."
A third article tells us that the health risks for patients who have both conditions are significantly higher than those who don't but it doesn't conclude that the 2 conditions are related or causative.
The results of the search aren't encouraging to support your claim. That doesn't necessarily mean that you shouldn't proceed to file but it does mean that a nexus letter from a physician is likely to be required to win the award. You should speak to your physician about whether or not he or she would consider such a statement and go from there.
