The VA rates sleep apnea at 0%, 30%, 50%, or 100% under Diagnostic Code 6847. The key threshold is 50%, which applies when your sleep apnea requires the use of a breathing-assistance device such as a CPAP machine — the most common outcome for diagnosed veterans. Sleep apnea is very often claimed as secondary to PTSD, sinusitis/rhinitis, asthma, or weight gain from psychiatric medication, making it one of the highest-value secondary claims.
Diagnostic code
DC 6847
How the rating works
0% = asymptomatic but documented; 30% = persistent daytime hypersomnolence; 50% = requires a CPAP or other breathing device; 100% = chronic respiratory failure with CO₂ retention, or requires a tracheostomy. A prescribed CPAP is the difference-maker for the 50% rating.
Secondary conditions to watch for
These are commonly connected to sleep apnea — each can be rated on top of it with a medical nexus. Most veterans leave these on the table.
Secondary to PTSD
A large body of medical literature links PTSD to obstructive sleep apnea — one of the most established secondary pathways.
Secondary to sinusitis / rhinitis
Chronic nasal obstruction can cause or aggravate apnea.
Secondary to weight gain
Weight gain from service-connected conditions or their medications can drive apnea.
Evidence that wins this claim
- A sleep study (polysomnogram) confirming the diagnosis.
- A CPAP prescription — critical for the 50% rating.
- A nexus opinion connecting the apnea to a primary service-connected condition (e.g., PTSD).
- Lay statements describing snoring, gasping, and daytime fatigue dating back to service.
Sleep apnea — frequently asked questions
- What VA rating does sleep apnea get?
- It is rated 0%, 30%, 50%, or 100% under DC 6847. Most diagnosed veterans reach 50% because their treatment requires a CPAP machine.
- Can I claim sleep apnea as secondary to PTSD?
- Yes — it is one of the most common and well-supported secondary claims. You need a current diagnosis (sleep study) and a medical nexus opinion linking the apnea to the service-connected PTSD.
- Does a CPAP machine guarantee 50%?
- If the apnea diagnosis is established and treatment requires a breathing-assistance device like CPAP, the schedule assigns 50%. The prescription documenting the device is the key evidence.
