Sleep Apnea Syndromes Secondary to Bronchial Asthma
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Sleep Apnea Syndromes when it develops after Bronchial Asthma.
Why Sleep Apnea Syndromes Is Linked to Bronchial Asthma
Asthma-related inflammation can worsen airway obstruction at night
Primary condition · VASRD 6602
Bronchial Asthma
A chronic lung condition that causes wheezing, coughing, and difficulty breathing due to inflamed airways.
Secondary condition · VASRD 6847
Sleep Apnea Syndromes
Sleep apnea is a disorder where breathing repeatedly stops or becomes shallow during sleep, fragmenting rest and often leading to loud snoring, daytime fatigue, and difficulty concentrating. Left untreated, it's also linked to higher blood pressure and heart strain, which is part of why the VA rates it based on treatment need rather than just the diagnosis.
Sleep Apnea Syndromes VA Rating Tiers
The VA rates Sleep Apnea Syndromes the same way whether it's claimed directly or as secondary to Bronchial Asthma — severity of Sleep Apnea Syndromes itself determines the percentage.
| Rating | Criteria |
|---|---|
| 50% | Must use a CPAP machine to sleep safely. |
| 0% | Sleep apnea present, but no machine needed. |
Example combined rating
30% Bronchial Asthma + 50% Sleep Apnea Syndromes = 65%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 50% combine to 65%, not 80%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
Evidence for a Sleep Apnea Syndromes Secondary Claim
- •A polysomnography (sleep study) confirming the diagnosis - this is the evidence the rating schedule specifically requires.
- •A CPAP prescription along with compliance or usage reports, since device use is what supports the 50% tier.
- •Medical notes describing sleep-related symptoms like loud snoring, witnessed breathing pauses, or excessive daytime sleepiness.
