To file a VA sleep apnea disability claim, submit an Intent to File on VA.gov to lock in your effective date, then send VA Form 21-526EZ along with a sleep study, a doctor’s nexus letter, and a completed Disability Benefits Questionnaire that ties the condition to your military service either directly or through a disability the VA already recognizes. The strength of the medical evidence, not the paperwork, decides most claims.
Gather Your Evidence Before You File
A claim without supporting documents is a claim the VA will send back for more information. Four pieces of evidence carry almost every sleep apnea decision.
A Formal Sleep Study
A polysomnogram is the foundation. It records how many times your breathing stops per hour and confirms whether you have obstructive, central, or mixed sleep apnea. If the study leads to a CPAP prescription, that alone supports the 50 percent rating threshold under Diagnostic Code 6847.1eCFR. 38 CFR 4.97 – Schedule of Ratings, Respiratory System You can get a sleep study through a VA medical center or a private provider; private home sleep tests typically run $150 to $620 out of pocket.
A Nexus Letter
This is a written statement from a doctor explaining why your sleep apnea is connected to your service. It should reference your service records, walk through the medical reasoning, and cite relevant medical literature. For a secondary claim, the letter must explain how a condition the VA has already service-connected caused or worsened your sleep apnea. In most denied claims, this is the piece that was missing or too thin.
A Disability Benefits Questionnaire
The sleep apnea DBQ is a standardized form your doctor fills out for the VA’s rating specialists. It captures the specific symptoms the rating criteria turn on: persistent daytime sleepiness, use of a breathing device, carbon dioxide retention, and cor pulmonale. It also records the date and facility of your sleep study.2Veterans Benefits. Sleep Apnea Disability Benefits Questionnaire
Lay Statements
Written statements from a spouse, family members, or fellow service members can describe loud snoring, gasping during sleep, or daytime exhaustion, and they help establish when symptoms began. Buddy statements from people who shared sleeping quarters with you during service carry particular weight when your service medical records are silent.3U.S. Department of Veterans Affairs.

Connect Sleep Apnea to Your Service
A diagnosis alone is not enough. You have to show the VA how the condition ties back to your military service, and there are two working pathways.
Direct Service Connection
A direct connection means the sleep apnea started during active duty or was caused by something that happened there. Under 38 CFR 3.303, you need a current diagnosis, evidence of an in-service event or condition, and a medical opinion linking the two at the “at least as likely as not” standard, meaning at least a 50 percent probability.4eCFR. 38 CFR 3.303 – Principles Relating to Service Connection Direct claims are strongest when service medical records document heavy snoring, breathing interruptions, or chronic fatigue during service.
Secondary Service Connection
If you cannot tie sleep apnea directly to service, you can still qualify if a condition the VA already service-connected caused or worsened it. Under 38 CFR 3.310, common secondary pathways include:
- PTSD and other mental health conditions, where medical evidence supports a link between psychological trauma and sleep disturbance.
- Service-connected GERD, which VA decisions have recognized can aggravate sleep apnea.5Board of Veterans’ Appeals. Citation Nr 19158332 – Service Connection for Sleep Apnea Secondary to GERD
- Service-connected respiratory conditions or sinusitis that restrict breathing.
- Weight gain caused by a service-connected injury that limits mobility, since excess weight is a major risk factor for airway obstruction.
For aggravation claims, the VA requires medical evidence of your baseline sleep apnea severity before the aggravation began, and the nexus opinion has to explain how the service-connected condition made it worse, not just that the two are related.6eCFR. 38 CFR 3.310 – Disabilities That Are Proximately Due to, or Aggravated by, Service-Connected Disease or Injury
One boundary worth knowing: sleep apnea is not on the PACT Act’s list of conditions presumed caused by toxic exposure. Burn pit exposure by itself will not carry a sleep apnea claim. If the PACT Act gives you a service-connected respiratory condition, though, that condition can anchor a secondary claim for sleep apnea.
File an Intent to File First
Before you send the formal application, file VA Form 21-0966, the Intent to File. It takes a few minutes on VA.gov and sets a potential effective date for your benefits. If your claim is later approved, you may receive retroactive payments covering the months between the Intent to File and the decision.7Veterans Affairs. Submit an Intent to File
You then have one year to submit the completed VA Form 21-526EZ. Miss that window and the potential effective date expires along with the back-pay advantage.8Veterans Affairs. About VA Form 21-0966
Submit VA Form 21-526EZ
VA Form 21-526EZ is the formal application. List sleep apnea as your condition, provide your service dates and Social Security number, and identify every medical facility, VA and private, where you have received treatment.3U.S. Department of Veterans Affairs. File for Disability Compensation With VA Form 21-526EZ
Filing Online
Uploading the application and supporting documents through VA.gov is the fastest option. The system returns a tracking number that documents your filing date, and digital claims move through processing faster than paper ones.
Filing by Mail or in Person
To file on paper, mail the completed form and supporting documents to:
Department of Veterans Affairs
Claims Intake Center
PO Box 4444
Janesville, WI 53547-4444
Certified mail with return receipt creates a delivery record. You can also drop the claim off at a local VA regional office.9Veterans Affairs. How to File a VA Disability Claim
The Fully Developed Claim Option
If your evidence is already assembled, submit a Fully Developed Claim (FDC). You send the medical records, nexus letter, DBQ, and lay statements together with the application and certify that no additional evidence exists. FDC claims move faster because the VA does not have to request records.10Veterans Affairs. Fully Developed Claims Program If the VA later needs more records, it simply moves the claim to the standard track without penalty. Submitting new evidence after you file an FDC, though, will automatically bump it off the faster track.
The C&P Exam and What Comes Next
Once the VA has your claim, it schedules a Compensation and Pension (C&P) examination. The examiner reviews your sleep study, nexus letter, and service records, confirms the diagnosis, and completes the sleep apnea DBQ, noting whether you have persistent daytime sleepiness, whether you use a breathing device, and whether you show signs of chronic respiratory failure or cor pulmonale.2Veterans Benefits. Sleep Apnea Disability Benefits Questionnaire A VA rating specialist uses those findings to decide the claim.
As of mid-2025, the VA reported average claim processing of about 132 days, roughly four and a half months.11VA News. VA Processes More Than 2M Disability Claims in Record Time The decision letter lists your rating percentage, monthly compensation amount, and effective date.
What Your Rating Will Pay
Sleep apnea is rated under Diagnostic Code 6847 at four levels: 0 percent (documented but asymptomatic), 30 percent (persistent daytime sleepiness that interferes with normal activity), 50 percent (requires a breathing assistance device such as a CPAP), and 100 percent (chronic respiratory failure with carbon dioxide retention, cor pulmonale, or a tracheostomy).1eCFR. 38 CFR 4.97 – Schedule of Ratings, Respiratory System Most veterans who use a CPAP fall at the 50 percent level.
For 2026, monthly compensation for a veteran with no dependents is $552.47 at 30 percent, $1,132.90 at 50 percent, and $3,938.57 at 100 percent. Veterans rated 30 percent or higher who have a spouse, children, or dependent parents receive additional amounts on top of the base rate.12U.S. Department of Veterans Affairs.

If the VA Denies Your Claim
A denial is not the end of the process. You have three review options, each with a one-year window from your decision letter:
- A Supplemental Claim, if you have new and relevant evidence the VA did not consider. Filing within one year preserves your original effective date.
- A Higher-Level Review, if you believe the VA made an error. A senior reviewer looks at the same evidence, and you can request an informal conference to point out mistakes.
- A Board Appeal, which sends your case to a Veterans Law Judge. You can choose direct review, submit additional evidence, or request a hearing.
Sleep apnea denials most often come down to a weak nexus letter or thin evidence connecting the condition to service. A Supplemental Claim built around a stronger medical opinion is usually the most effective next step.13Veterans Affairs. Decision Reviews FAQs
