How the VA rates sleep apnea
Sleep apnea is rated under 38 CFR Part 4, diagnostic code 6847 (sleep apnea syndromes). The rating is based on the severity of the condition and treatment requirements — not on how tired you feel or how badly your sleep is disrupted.
Sleep apnea rating levels in detail
Sleep disorder breathing documented by sleep study but without significant symptoms. No compensation is paid, but service connection is established — which matters if the condition worsens later.
Daytime sleepiness that persists despite treatment or without use of a breathing device. The veteran is excessively sleepy during waking hours. This level is often temporary — if the examiner recommends CPAP and it is prescribed, the rating moves to 50%.
The veteran requires use of a CPAP, BiPAP, APAP, or other breathing assistance device. This is the most commonly awarded sleep apnea rating. The key evidence is a prescription for the device. If you use a CPAP and it was prescribed, you qualify for 50%.
Chronic respiratory failure with carbon dioxide retention, cor pulmonale, or requires tracheostomy. Rare — applies to the most severe cases with documented systemic effects.
Sleep apnea secondary to PTSD
Sleep apnea secondary to PTSD is one of the most commonly granted secondary service connection claims. The medical rationale: PTSD disrupts normal sleep architecture, increasing arousal thresholds and contributing to the development or worsening of obstructive sleep apnea.
To establish secondary service connection, you need:
- A current diagnosis of sleep apnea (sleep study)
- An existing service-connected condition (usually PTSD)
- A medical nexus opinion linking the two
Private nexus letters from sleep medicine physicians or psychiatrists are highly effective here. The opinion typically states that PTSD "at least as likely as not" caused or aggravated the sleep apnea.
Sleep apnea secondary to back injuries
Sleep apnea can also be claimed secondary to cervical spine (neck) conditions. Cervical instability and related muscle tension can narrow the airway during sleep, contributing to obstructive events. Veterans with service-connected cervical spine conditions who develop sleep apnea should explore this route with a physician familiar with VA secondary claims.
Additionally, weight gain resulting from limited mobility caused by a service-connected orthopedic condition can be documented as a contributing factor to sleep apnea.
The 50% + PTSD combination: the most common high-value claim
This is why sleep apnea secondary to PTSD is one of the most impactful claims a veteran with PTSD can file. A single secondary condition — properly documented and nexus-supported — can push a veteran from 70% to 90%, adding over $6,600 per year in tax-free compensation.
Evidence needed for a sleep apnea claim
- Sleep study (polysomnography) — documenting obstructive sleep apnea diagnosis and AHI score
- CPAP prescription — confirming that a breathing device is required
- In-service nexus or secondary nexus — connecting the condition to military service or a service-connected condition
- Service records showing in-service symptoms — if claiming direct service connection
If the initial claim is for direct service connection without clear in-service records, a secondary claim from PTSD or orthopedic conditions is often the stronger path.
What if your sleep apnea claim was denied?
Common denial reasons:
- No documented in-service symptoms or treatment for sleep issues
- Nexus opinion that the sleep apnea is not related to military service
- Failure to claim secondary service connection when direct connection wasn't established
- Inadequate C&P examination (examiner did not review service records)
A denial on direct connection does not close the door on a secondary claim. If you have service-connected PTSD, depression, or orthopedic conditions, a new supplemental claim for secondary service connection with a private nexus letter is often successful.
Frequently asked questions
No. The 50% rating is based on the requirement to use a breathing device — not on whether you actually use it nightly. If a physician has prescribed a CPAP or BiPAP, you qualify for 50% regardless of compliance. However, failure to use prescribed treatment can be used in future re-examinations, so it's worth documenting compliance if possible.
Yes, but it requires severe disease — chronic respiratory failure with carbon dioxide retention (hypercapnia), cor pulmonale (right heart failure from lung disease), or requiring a tracheostomy. These criteria apply to a small minority of veterans with the most severe sleep apnea. Most veterans with CPAP-dependent sleep apnea are rated at 50%.
The VA can propose a rating reduction if a re-examination shows material improvement. For sleep apnea, improvement typically means the condition no longer requires a breathing device. If you stop needing the CPAP, the rating would likely drop from 50% to 30% or 0%. The VA must follow specific procedural protections before reducing a rating that has been in place for five or more years.
Yes. Sleep apnea is rated under the Respiratory System in 38 CFR Part 4 (DC 6847). This means it cannot be combined with another respiratory condition that represents the same disability (pyramiding rule). However, it can be combined with mental health conditions, musculoskeletal conditions, and other systems without issue.
Yes, through secondary service connection. Sleep apnea often goes undiagnosed during service because service members avoid reporting sleep problems out of concern for their career. A post-service diagnosis combined with a medical opinion connecting it to PTSD, cervical spine injury, or other service-connected conditions is a viable path to service connection even with no in-service diagnosis.
