Sleep Apnea
Sleep apnea is the highest-leverage condition many veterans miss. If you require a CPAP machine, you qualify for the 50% rating — automatically. The bigger question is whether your sleep apnea is service-connected, either directly or as secondary to PTSD, sinusitis, weight gain from a service-connected disability, or other qualifying conditions.
Rating tiers under 38 CFR § 4.97, DC 6847
The VA rates sleep apnea at these schedular tiers. Most veterans land at the middle tiers — extreme tiers require correspondingly extreme documentation.
Asymptomatic but with documented sleep disorder breathing.
Persistent daytime hypersomnolence.
Requires use of breathing assistance device such as continuous airway pressure (CPAP) machine.
Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or requires tracheostomy.
Evidence the C&P examiner needs
Build the record before the exam. Walk in with documentation, walk out with a stronger rating.
- 01
Sleep study (polysomnogram) showing AHI (apnea-hypopnea index) of 5 or higher
- 02
CPAP prescription on letterhead or in medical records
- 03
Lay statement from spouse describing in-service snoring, witnessed apnea events, or daytime fatigue
- 04
Buddy statement from barracks or deployed living quarters confirming snoring or witnessed breathing pauses
- 05
Nexus letter from a sleep specialist if filing as secondary to PTSD, sinusitis, or weight-related condition
- 06
Service treatment records noting any sleep complaint, sinus issue, or weight gain
Secondary conditions to file alongside
These conditions frequently develop as a consequence of sleep apnea and are often missed. Each can be filed as a secondary claim and add to your combined rating.
PTSD (where sleep apnea is secondary)
Established medical literature supports sleep apnea as a secondary condition to PTSD. The IRR (Independent Medical Reviewer) reports cite this connection frequently.
Hypertension (secondary to sleep apnea)
Untreated sleep apnea drives blood pressure elevation. A successful sleep apnea claim often supports a follow-on hypertension secondary.
Type 2 diabetes (secondary to sleep apnea)
Sleep apnea is recognized as contributing to insulin resistance; secondary diabetes claims succeed when supported by an endocrinology nexus letter.
Common mistakes that lower the rating
- 01
Filing without a sleep study — the VA cannot rate without the polysomnogram showing AHI
- 02
Not establishing in-service onset — without buddy or spouse statements describing snoring or witnessed apnea during service, the connection often fails
- 03
Skipping the secondary-condition pathway — if PTSD is already service-connected, sleep apnea has a much easier road as secondary than as direct
Pro tip
If you have PTSD service-connected and a recent sleep apnea diagnosis, file the sleep apnea claim as secondary to PTSD. Cite Independent Medical Examiner literature on the PTSD-OSA connection. This pathway has a roughly 70% approval rate compared to 30% for direct claims without strong in-service evidence.
