Sleep Apnea: VA Rating Criteria

Plain-language guide

What this rating actually turns on

Sleep apnea is rated under 38 CFR 4.97, Diagnostic Code 6847, and the axis is treatment required, not test severity. The 50 percent level turns on whether you require a breathing assistance device such as a CPAP machine; the 30 percent level on persistent daytime hypersomnolence; 100 percent is reserved for chronic respiratory failure with carbon dioxide retention, cor pulmonale, or a required tracheostomy. Your apnea-hypopnea index does not set the percentage — a veteran with moderate OSA on a prescribed CPAP and one with severe OSA on a prescribed CPAP sit at the same level.

Because of that structure, the contested ground in most sleep apnea claims is service connection, not the percentage. Sleep apnea is frequently diagnosed years after separation, so you need evidence of in-service incurrence or aggravation plus a medical nexus to the current diagnosis under 38 CFR 3.303 — or a link to an already service-connected condition, since 38 CFR 3.310 allows service connection for disabilities proximately due to, or aggravated by, a service-connected disability.

What the C&P exam measures

The Sleep Apnea DBQ tracks the rating criteria almost line by line. The examiner documents whether a sleep study has been performed (date, facility, and results), whether continuous medication is required, and checks boxes for the exact findings the schedule rates: persistent daytime hypersomnolence, cor pulmonale, carbon dioxide retention, chronic respiratory failure, and tracheostomy, plus the condition’s functional impact on your ability to work. The DBQ is on VA’s public list, so a private physician who treats you can complete it.

What to have in your file

• The sleep study report. Even the 0 percent criterion requires “documented sleep disorder breathing” (DC 6847), and the DBQ asks for the study by name, date, and results.
• Documentation that the device is medically required — the prescription and treatment notes. The 50 percent criterion reads “requires use of breathing assistance device,” so the record must show medical necessity, not just ownership of a machine.
• In-service evidence: service treatment records noting snoring, apneic episodes, or chronic fatigue, and lay statements from people who served with you describing what they observed.
• A nexus opinion from a physician connecting the current diagnosis to service or to a service-connected condition, with reasoning.

Common mistakes

• No sleep study. A symptom-based diagnosis without a confirming study leaves nothing for the rater to anchor under DC 6847’s wording.
• Assuming CPAP use alone settles it. Without records showing the device is prescribed and required, the 50 percent criterion isn’t documented.
• Filing with a current diagnosis and nothing else. A post-service diagnosis without in-service evidence or a nexus opinion fails the § 3.303 elements regardless of severity.
• Stacking respiratory ratings. Under 38 CFR 4.96(a), ratings under DCs 6600–6817 and 6822–6847 are not combined with each other; coexisting respiratory conditions get a single rating under the predominant disability, with possible elevation to the next level.

Worth knowing

VA published a proposed rule on February 15, 2022 (87 FR 8474) that would rebuild DC 6847 around treatment effectiveness: 0 percent if asymptomatic with or without treatment, 10 percent where treatment yields incomplete relief, 50 percent only where treatment is ineffective or cannot be used due to comorbid conditions, and 100 percent only with end-organ damage. No final rule has been published, and the criteria currently in the CFR remain the law. Claims are decided under the criteria in effect, but this is the single most consequential pending change for this condition and worth watching. A VA-accredited representative or VSO can assist at no cost.
