Sleep apnea secondary to PTSD — the pathway raters actually accept.
If PTSD is already service-connected, obstructive sleep apnea is one of the most well-documented secondary claims a veteran can file. Brightview writes the medical opinion that ties them together.
Do you qualify?
You likely have a claim worth discussing if all three are true
- PTSD is already service-connected at any rating percentage. There is no minimum.
- You have a sleep apnea diagnosis confirmed by a sleep study — in-lab polysomnography or an at-home test. A suspicion of sleep apnea is not enough; the VA requires the study.
- You have not yet had a physician explain the connection in writing, or the opinion in your file was rejected as too brief.
If your sleep study came years after separation, that does not disqualify you. Secondary service connection does not require the condition to have appeared during service — it requires a medical link to a condition that did.
One clinic. One psychiatrist. One standard.
Brightview writes sleep apnea secondary to PTSD nexus letters the VA can't ignore.
Most sleep apnea secondary to PTSD claims aren't denied because the veteran doesn't deserve service connection — they're denied because the letter behind the claim wasn't written to the VA's evidentiary standard. Dr. Jessica Allen writes every Brightview letter personally, using the exact clinical and legal language raters are trained to look for.
Why other sleep apnea secondary to PTSD letters get denied
The letters raters throw out
- Letter says 'PTSD is linked to sleep apnea' without explaining the physiologic mechanism.
- No citation to the PTSD–OSA literature (sleep fragmentation, autonomic arousal, REM disruption, weight gain from psychotropics).
- C&P examiner blames obesity and never addresses PTSD-driven weight gain, insomnia, or medication side effects.
- Aggravation theory ignored when OSA predates PTSD but worsens after service.
How Brightview wins them
What Dr. Allen puts in every sleep apnea secondary to PTSD letter
- 38 CFR 3.310 causation and aggravation opinion tied to your PTSD symptom history.
- Explains sleep fragmentation, upper-airway muscle tone changes, and REM-related airway collapse in plain, VA-relevant language.
- Addresses obesity/weight gain from PTSD medications (SSRIs, mirtazapine, quetiapine) when applicable.
- Cites peer-reviewed medical literature the VA is trained to weigh.
VA Rating Criteria
What is sleep apnea rated at?
Under the current rating schedule, obstructive sleep apnea is evaluated under Diagnostic Code 6847:
| Rating | Criteria |
|---|---|
| 0% | Documented sleep-disordered breathing, asymptomatic. |
| 30% | Persistent daytime hypersomnolence. |
| 50% | Requires use of a breathing assistance device. |
| 100% | Chronic respiratory failure with CO2 retention, cor pulmonale, or requires tracheostomy. |
The 50 percent level is where most service-connected OSA claims land, because it turns on whether a breathing assistance device is medically required — not on how severe the apnea-hypopnea index is.
Because 50 percent is a substantial evaluation, adding it to an existing combined rating often moves a veteran into a higher compensation bracket. How much depends on your other ratings, your dependents, and your effective date. VA combined ratings do not add arithmetically, so the effect is specific to your file.
Rating criteria are currently under review. Both a pending VA rulemaking and proposed legislation would change how sleep apnea is rated for future claims, moving away from device-based criteria toward treatment effectiveness. Nothing has changed yet, and existing compensation would be protected under the proposed language. Read the full explanation of the proposed changes →
Secondary pathways
Once sleep apnea is service-connected, what else can you claim?
Untreated or poorly controlled OSA produces repeated oxygen desaturation, fragmented sleep, and sustained autonomic activation. Where the medical evidence supports it, veterans with service-connected sleep apnea may pursue additional claims for:
Whether any of these applies depends on your records and your timeline. This is worth raising on your consultation call — veterans frequently discover they have more than one viable claim.
Don't count yourself out
You may still qualify for sleep apnea secondary to PTSD — even if you've been told you don't.
Half the veterans we help were told they had no case. They did. They just didn't have the right medical opinion in the file yet.
- You were diagnosed with sleep apnea years after separation.
- The C&P examiner said your OSA is 'due to weight.'
- You were already denied on a direct-service-connection theory.
- Your BMI is in the overweight or obese range — that is often part of the PTSD chain, not a defeater.
