What Is Sleep Apnea?
Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. There are two primary types relevant to VA claims:
- Obstructive Sleep Apnea (OSA) — the most common type, caused by the airway collapsing or becoming blocked during sleep. This is the type most veterans are diagnosed with.
- Central Sleep Apnea — caused by the brain failing to signal the muscles that control breathing. Less common but can be connected to TBI or neurological conditions.
The VA rates sleep apnea under Diagnostic Code (DC) 6847, found in 38 CFR 4.97 — the Schedule of Ratings for the Respiratory System.
VA Rating Tiers for Sleep Apnea (DC 6847)
0% — Asymptomatic but With Documented Disorder
Sleep apnea is confirmed by a sleep study, but there are no current symptoms or the condition does not require treatment.
30% — Persistent Daytime Hypersomnolence
You experience persistent excessive daytime sleepiness (hypersomnolence) that is not adequately managed without treatment, but you do not require a breathing assistance device.
50% — Requires Use of a Breathing Assistance Device (CPAP)
You require the use of a CPAP machine or other breathing assistance device. This is the most common rating for veterans with sleep apnea. If you have a CPAP prescription, you qualify for 50%.
100% — Chronic Respiratory Failure with Cor Pulmonale
Chronic respiratory failure with carbon dioxide retention, the need for a tracheostomy, or cor pulmonale (right-sided heart failure caused by lung disease). This is rare but represents the most severe form of the condition.
Direct vs. Secondary Service Connection
Sleep apnea can be service-connected in two ways:
Direct Service Connection
You were diagnosed during service or can show symptoms began during service. Evidence includes in-service sleep studies, buddy statements from bunkmates who witnessed choking/gasping during sleep, and STR entries noting fatigue or sleep complaints.
Secondary Service Connection
Sleep apnea developed as a result of — or was aggravated by — another service-connected condition. Common secondary pathways include:
- PTSD — PTSD medications cause weight gain, which contributes to OSA; research also links PTSD directly to sleep-disordered breathing
- Weight gain from medications — psychiatric medications, pain medications, and steroids prescribed for service-connected conditions often cause significant weight gain
- Toxic exposure — burn pit exposure (PACT Act), Agent Orange, and other environmental hazards are linked to respiratory conditions including sleep apnea
- TBI — traumatic brain injury can cause central sleep apnea through damage to the brain's respiratory control centers
- Sinusitis/rhinitis — chronic nasal and sinus conditions can contribute to airway obstruction
Evidence Needed for a Sleep Apnea Claim
- Sleep study (polysomnography) — an official sleep study is required for diagnosis. The VA will not rate sleep apnea without one. It must show an Apnea-Hypopnea Index (AHI) of 5 or higher.
- CPAP prescription — your doctor's prescription for CPAP establishes the need for a breathing assistance device (50% rating)
- CPAP compliance data — download reports from your CPAP machine showing regular use; this demonstrates ongoing need
- Buddy statements — statements from a spouse, roommate, or fellow service members describing witnessed apnea episodes (gasping, choking, stopping breathing during sleep)
- Nexus letter — for secondary claims, a medical opinion linking sleep apnea to your service-connected condition is critical
- Weight and medication records — if claiming secondary to medication-induced weight gain, document your weight before and after starting the medication
What to Expect at the C&P Exam
The C&P exam for sleep apnea is typically conducted by a pulmonologist or general practitioner. The examiner will:
- Review your sleep study results and medical records
- Ask when you first noticed symptoms (snoring, daytime fatigue, gasping)
- Confirm whether you use a CPAP and how often
- Ask about the impact on your daily life and work
- For secondary claims, evaluate the relationship between sleep apnea and your primary condition
- Provide a medical opinion on service connection
Tip: Bring your CPAP compliance data printout to the exam. If you gained weight after starting a service-connected medication, bring documentation showing your weight timeline.
Common Mistakes to Avoid
- Not getting a sleep study — the VA will not rate sleep apnea without polysomnography results, period
- Filing direct when secondary is stronger — if you were not diagnosed during service, a secondary claim through PTSD or medication weight gain often has a clearer nexus
- Inconsistent CPAP use — if you stop using your CPAP, the VA may reduce your rating at re-examination; maintain consistent use and compliance data
- Not documenting weight gain — if weight gain from medications is your nexus, you need before-and-after weight records
- Ignoring the PACT Act — if you were exposed to burn pits or other toxins, sleep apnea may qualify under PACT Act presumptives; check your eligibility
Frequently Asked Questions
- Do I automatically get 50% if I use a CPAP?
- Yes — if your sleep apnea is service-connected and you are prescribed a CPAP or other breathing assistance device, the VA assigns a 50% rating under DC 6847.
- Can I claim sleep apnea secondary to PTSD?
- Yes, and this is one of the most common secondary claim pathways. You will need a nexus letter from a doctor explaining the medical connection — typically through medication-induced weight gain or the direct physiological effects of PTSD on sleep.
- What if I was diagnosed after service?
- That is common. Sleep apnea often goes undiagnosed for years. Buddy statements from service members who witnessed your snoring and gasping during service, combined with a nexus letter, can bridge the gap between service and diagnosis.
- Will the VA pay for my CPAP machine?
- If your sleep apnea is service-connected, yes. The VA will provide a CPAP machine, supplies (masks, hoses, filters), and replacement equipment through VA healthcare.
- Can my sleep apnea rating be reduced?
- Yes. If a future C&P exam shows you no longer need a CPAP, the VA can propose a reduction. Maintain your CPAP compliance data and continue treatment to protect your rating.
