The Sleep Apnea DBQ is one of the shortest forms in the rating system. It is also one of the highest-leverage exams, because the difference between 0%, 30%, and 50% is decided by just three boxes the examiner checks. If the right box is checked, you get 50% under DC 6847. If the wrong box gets checked — usually because of a careless answer about CPAP use — you drop to 30% or 0%. The whole DBQ is structured around confirming a sleep-disordered-breathing diagnosis and identifying the level of treatment required.
What the examiner is filling out
The DBQ (current title: Sleep Apnea Disability Benefits Questionnaire) has four sections:
- Diagnosis — obstructive, central, or mixed sleep apnea. Plus the date of the sleep study (polysomnography or HSAT) that established the diagnosis.
- Sleep study results — AHI / RDI / lowest oxygen saturation noted. This does not affect the rating tier directly but establishes the disability.
- Current symptoms & treatment — the box-checking section. This is where the rating tier is decided.
- Impact on occupational functioning — brief; not tier-decisive but useful for TDIU support.
The § 4.97 DC 6847 schedule
You have OSA on paper but no daytime symptoms and no prescribed therapy. Rare in practice — if a sleep study confirmed apnea, daytime symptoms almost always exist.
Documented daytime sleepiness that interferes with normal activities, but no CPAP / BiPAP prescribed. This is where you land if the examiner concludes you do NOT require CPAP.
Prescribed CPAP, BiPAP, APAP, or similar PAP therapy. The regulation says 'requires use' — that means prescribed and used, not necessarily used 7 nights a week. This is the most-common rating for service-connected sleep apnea.
Severe end-stage disease. Uncommon. Cor pulmonale = right-heart failure from chronic lung disease. Tracheostomy is rare in OSA, more common in severe central sleep apnea or other complicating conditions.
The phrases that secure the 50% tier
Magic words for this tier
If you are prescribed CPAP, BiPAP, or APAP:
- “My doctor prescribed CPAP. I use it as directed.”
- “My CPAP is required to manage my breathing during sleep.”
- “Before treatment, my [partner / roommate] said I stopped breathing in my sleep.”
- “I still feel tired during the day even with CPAP — that is normal for OSA.”
Magic words for this tier
For the 30% tier (if no CPAP):
- “I fall asleep during meetings / driving / watching TV.”
- “I have to nap during the day to function.”
- “My partner has observed loud snoring and breathing pauses.”
- “My morning headaches and fatigue have not improved.”
What NOT to say
What NOT to say
- “I only use the CPAP sometimes.” → paraphrased as “does not require CPAP” → drops you from 50% to 30%.
- “The CPAP fixed everything — I feel great now.” → can be read as “condition resolved with treatment.”
- “I gave up on the mask after a few months.” → suggests no current treatment requirement; talk to the prescribing physician about a different mask or APAPbefore the exam if there is a fit problem.
- “I’ve always been a snorer.” → without aggravation framing, this suggests pre-service onset and undercuts direct service connection.
- “I think it’s mostly because I gained weight.” → on a secondary to PTSD claim, the weight gain from PTSD medication is the nexus — do not separate the two. See the sleep apnea secondary to PTSD article for the framing.
If you do not yet have a sleep study
You cannot win this claim without the polysomnography or HSAT report. The schedule requires documented sleep-disordered breathing. The C&P examiner cannot diagnose OSA on the day of the exam — they read the report.
If you suspect OSA but have not been tested:
- Ask your VA or civilian PCP for a sleep medicine referral.
- HSAT (home sleep test) is faster and adequate for most uncomplicated OSA. Insurance and VA usually approve it without a fight.
- An in-lab polysomnography is required if you have comorbidities (heart failure, neuro disease, severe insomnia) or for titration to set the CPAP pressure.
File the claim only after the study is complete and you have the report. Filing without the study leads to a denial that takes longer to fix than just waiting for the test.
If you are filing secondary (especially to PTSD)
A secondary sleep apnea claim has all the same DBQ mechanics, but the examiner is also being asked the nexus question: was the OSA caused or aggravated by the service-connected primary? The DBQ has a section for the examiner’s medical opinion on that link.
What to bring up
- Weight gain that correlated with PTSD medication (mirtazapine, paroxetine, quetiapine).
- Chronic sleep fragmentation from PTSD nightmares.
- The nexus letter your private doctor wrote (bring a copy).
