Sleep Apnea C&P Exam Prep

Everything that changes your rating, nothing that doesn’t. Read it once before you go.

About a 4-minute read

Before your exam

  1. Pull your CPAP compliance report (usage hours and nights). Bring a printed copy.
  2. Bring your sleep study with the AHI score and lowest oxygen level.
  3. Bring a buddy statement from whoever hears you snore, gasp or stop breathing.
  4. Write down your diagnosis date and who diagnosed you. If it was in service, say so.
  5. List your sleep meds and dosages, plus related problems: morning headaches, daytime sleepiness, high blood pressure.

During the exam

What the examiner measures

The examiner checks three things: do you need a breathing device (CPAP/BiPAP), do you have persistent daytime sleepiness, and is there respiratory failure. Those are the only things that set the rating.

Three things to say or show

  • “I use a CPAP.” Say the machine, the settings and how many nights a week. A prescribed CPAP is the 50% criterion.
  • Your sleepiness, with examples. Falling asleep in meetings, pulling over while driving, needing multiple alarms, waking up exhausted.
  • Your numbers. AHI score, how low your oxygen drops at night, and when you were diagnosed.

Mistakes that sink ratings

  • Saying “I’m fine” or “I manage.” The examiner writes down exactly what you say. Describe your worst nights and days, honestly.
  • Hiding low CPAP use. If you stopped using it, bring the medical reason (claustrophobia, skin irritation, mask fit) in writing.

After

  • Request the exam report (DBQ) through VA.gov or your VSO and read it. Check that CPAP use is recorded.
  • Forgot something? Send a short written statement (VA Form 21-4138) to the claim file right away.
  • Keep using the CPAP and keep your follow-ups. Treatment records are what back up the rating later.

Rating criteria

0%Asymptomatic but documented sleep-disordered breathing
Go deeper: regulations, secondaries and why this works

How VA rates it

Sleep apnea is rated under 38 CFR 4.97, diagnostic code 6847. The 50% level turns on one fact: a doctor prescribed a breathing assistance device. That is why the CPAP question comes first and why your compliance data matters.

VA proposed in 2022 to rate sleep apnea by how well treatment works instead. As of this writing that proposal has not been finalized, so the table above is still the law.

Secondary conditions to raise

Sleep apnea commonly causes or worsens hypertension, heart disease, depression and anxiety, memory problems, and erectile dysfunction.

It is also often secondary to PTSD, weight gain from other service-connected conditions, or a deviated septum or sinus condition. Mention the ones you have; each can be a separate claim.

Why "worst day" matters

VA rates functional impact, and your average day understates it.

Think about the morning you could not stay awake at work, the drive where you had to pull over, the separate bedrooms because your spouse was scared by your breathing. Say those out loud.

Bringing someone with you

Most examiners allow a spouse or friend in the room; ask first. A witness describing your nighttime breathing is powerful because you are asleep when it happens.
