What if I have a sleep study but no CPAP?

You likely qualify for the 30% rating based on documented hypersomnolence. Discuss a CPAP evaluation with your provider if your symptoms warrant it, since the prescription itself is what typically drives the higher 50% rating.

Does a home sleep test count the same as an in-lab study?

Generally yes for diagnostic purposes, though your provider may recommend an in-lab study depending on your specific symptom presentation.

Can sleep apnea reach 100% without a tracheostomy?

Yes, if you have documented chronic respiratory failure with carbon dioxide retention or cor pulmonale — a tracheostomy is one qualifying path to 100%, not the only one.

VA Sleep Apnea Rating Criteria: 0%, 30%, 50%, 100%

How the VA rates obstructive sleep apnea under diagnostic code 6847 — the role of CPAP, hypersomnolence, and exactly what the 100% threshold requires.

Quick answer

Sleep apnea is rated 0%, 30%, 50%, or 100% under DC 6847. A CPAP prescription generally drives the 50% rating regardless of tolerance. The 100% level requires chronic respiratory failure with carbon dioxide retention, cor pulmonale, or a required tracheostomy.

The VA rates sleep apnea under Diagnostic Code 6847. The difference between rating levels often hinges on a handful of specific findings that examiners check during the C&P exam. Knowing what each level requires lets you advocate for an accurate rating — and identify when an under-rating warrants an appeal.

Rating Criteria

0%

Asymptomatic, with documented sleep disorder breathing confirmed by testing.

30%

Persistent daytime hypersomnolence (excessive sleepiness) documented in treatment records.

50%

Requires use of a breathing assistance device such as CPAP, regardless of how well the device is tolerated.

100%

Chronic respiratory failure with carbon dioxide retention, or cor pulmonale, or a required tracheostomy — the top rating is reserved for genuinely severe, complicated cases.

Evidence That Drives the Rating

A sleep study (polysomnogram) documenting your AHI (Apnea-Hypopnea Index) score
CPAP prescription and any follow-up compliance or usage records
A spouse or partner statement describing observed apneic episodes, gasping, or breathing pauses during sleep

What to Expect at the C&P Exam

The examiner will complete the DBQ specific to sleep apnea. Bring symptom logs, treatment records, and a clear description of how the condition affects daily life and work. Describe your worst typical day, not your best day.

Why CPAP Is the Single Biggest Lever in This Claim

Because a prescribed CPAP machine alone generally supports the 50% rating — without needing to separately prove daily compliance or perfect tolerance — the prescription itself is worth more to your claim than almost any other single piece of evidence. If your provider has discussed CPAP but hasn't formally prescribed it yet, it's worth raising directly at your next appointment.

The Gap Between 0% and 30%

The distinction between an asymptomatic diagnosis (0%) and persistent daytime hypersomnolence (30%) often comes down to how clearly your treatment records document actual daytime symptoms, not just the sleep study result itself. A sleep study alone can support a diagnosis without necessarily documenting the hypersomnolence needed for the 30% level — make sure your provider notes daytime fatigue and its functional impact separately.

Common mistakes to avoid

Filing without a sleep study, which is the foundational piece of evidence for any sleep apnea claim.
Forgetting to include the CPAP prescription itself, which is what specifically supports the jump to 50%.
