Sleep Apnea Secondary to Anxiety Disorder Claim Guide
Sleep Apnea (VA diagnostic code 6847) is sometimes claimed as secondary to service-connected Anxiety Disorder (code 9400) under 38 CFR 3.310. We analyzed published Board of Veterans' Appeals decisions on that pairing; here is what they show. It is an encyclopedic reference, not a forecast.
The Numbers, from 1.9M Appeals
We analyzed the Board's published decisions and found sleep apnea (DC 6847) claimed as secondary to anxiety disorder (DC 9400) is a small but documented claim pool that wins more often than not once it reaches a merits decision.
How those 213 issues came out
Symptoms Recorded in Granted Sleep apnea Decisions
We analyzed 10,989 granted Board decisions involving sleep apnea for symptoms named in sentences about the condition (rating-criteria recitations excluded). Descriptive of the published record, what the Board wrote down, not a checklist of what to report.

ICD-10 Diagnosis Codes for Sleep Apnea
The ICD-10 diagnosis codes most commonly used for DC 6847, Sleep Apnea (the kind on your medical records, decision letter, or C&P exam report). VA rates the disability and its residuals, not the diagnosis itself, so coding can vary.
What a secondary claim on this pairing needs
Under 38 CFR 3.310 a secondary claim turns on three elements:
- A current diagnosis: a medical diagnosis of sleep apnea (the secondary).
- A service-connected primary: Anxiety Disorder, already service-connected (the primary). A 0% primary still counts.
- A medical nexus: a medical opinion linking the sleep apnea to the anxiety disorder, showing the primary caused or aggravated it.
See the Secondary Claim guide for the caused-versus-aggravated split, and the Nexus Letter guide for what makes the medical opinion strong.
Why sleep apnea is claimed secondary to anxiety disorder
Whether that medical link exists in any one case is a medical question decided on that case's own evidence (the nexus).
Caused By vs Aggravated By: What the Board Found
The outcome split above counts whole issues. This section goes one layer deeper. Under 38 CFR § 3.310 a secondary claim can be won two ways: the anxiety disorder caused the sleep apnea (§ 3.310(a)), or it aggravated an existing sleep apnea (§ 3.310(b)). Every grant rests on one or the other, so the numbers below divide up the granted claims only.
Direct causation is the route that carries most grants here: 96% of them found the anxiety disorder caused the sleep apnea, the rest found aggravation. A practical consequence for the nexus opinion: it should address both routes, because a medical opinion that only argues causation leaves the aggravation theory, a separate legal basis, on the table. See the caused-vs-aggravated guide for how the two theories differ.
On the other side: in 11 denied claims the Board looked at this pairing and found no link, meaning it decided the anxiety disorder neither caused nor worsened the sleep apnea. That is a separate group from the grants above, counted here so the picture is not one-sided.
We analyzed published Board decisions on this pairing to build this split. The grant split covers granted claims only; denied, remanded, and dismissed claims are not in it. Descriptive of the published record, not a prediction.
What VA Looks For: Tests, Records, and Diagnostic Codes
The record VA actually reviews centers on a small set of documents. We analyzed published Board decisions on these claims and ranked the records that appeared most often:
- A medical nexus opinion: the one record VA weighs most on a secondary claim, a doctor's statement linking your sleep apnea to your service-connected anxiety disorder and naming the mechanism.
- Sleep study (polysomnography) in the file
- CPAP prescribed or recommended
- Witness statements on snoring or stopped breathing
- In-service fatigue, snoring, or daytime sleepiness
- Weight gain documented during or since service
The diagnostic code involved: DC 6847 (Sleep Apnea). The rating levels for this code are in the rating section below.
Records ranked by how often published Board decisions cited them. The exam that captures most of this is covered in the C&P Exam section below. Source: Board of Veterans' Appeals decisions, RateMyVSO analysis.
The Evidence That Wins Sleep Apnea Secondary Claims
What veterans who win this pairing actually put in the file, and why each piece moves the claim.
- Sleep study with full results: Get a copy of your polysomnography report showing your apnea-hypopnea index (AHI), oxygen levels during sleep, and whether it's obstructive, central, or mixed apnea. The VA cannot rate sleep apnea without this. If you never had one, ask your doctor to order one now.
- Timeline of anxiety and sleep apnea: Pull your service and post-service medical records showing when your anxiety was first diagnosed versus when sleep apnea showed up. If anxiety came first, that supports the claim that it caused your apnea. If apnea came first, you're arguing anxiety made an existing problem worse (aggravation), and you need to say so directly.
- Medication list: Gather records of every anxiety medication you've taken, especially SSRIs, benzodiazepines, or other sedatives. These drugs can relax the muscles in your throat or slow your breathing drive during sleep. List the exact drug names and the dates you started them next to when your sleep apnea got worse.
- Weight and activity records: If you gained weight, get documentation of when. If the weight gain happened after your anxiety started, and you can show it came from anxiety-driven inactivity or stress eating, that weight gain supports your claim instead of hurting it. The VA will try to blame obesity alone, so this record matters.
- Mental health treatment notes: Bring therapy and psychiatry records that were written around the same time your sleep apnea developed. These show how severe and active your anxiety really was, not just what a single exam said.
- Statements from people who know you: Ask a spouse, family member, or battle buddy to write down what they've seen and heard, gasping, choking, tossing at night, and whether it got worse when your anxiety flared up. Firsthand accounts like this carry real weight with the Board.
- An independent nexus letter: This is the single most important document you can get. Find a sleep medicine doctor or former VA examiner, not your VA C&P examiner, to write a letter stating it is "at least as likely as not" that your anxiety caused or made your sleep apnea worse. The letter needs to name the specific reason (hyperarousal, medication side effects, anxiety-driven weight gain, or sleep disruption), not just say they're "related."
- A direct answer to both causation and aggravation: Make sure your claim and your doctor's letter address both possibilities under the law, that anxiety caused the apnea, or that it made an existing case worse. If your C&P exam says anxiety "doesn't directly collapse airways," your nexus letter should explain the indirect pathways the examiner missed, so the record doesn't leave that objection unanswered.
Evidence Cited in Published Sleep apnea Decisions
We analyzed 77,405 published Board decisions involving sleep apnea for condition-specific evidence, counting only case-specific mentions (boilerplate recitations excluded). "Favorable" is the share of decisions citing that evidence where every issue was granted or the outcome was mixed; the baseline across all these decisions is 58%. Evidence appearing in a decision does not mean it decided the case. Descriptive of the published record, not a prediction.

Board Grants on This Pairing, Dissected
The Board has granted service connection for sleep apnea as secondary to generalized anxiety disorder (or a psychiatric disability that includes GAD) in several recent decisions. In each case, the Board found the VA examiner's negative opinion inadequate and gave more weight to a private opinion that addressed the veteran's specific psychiatric symptoms and their link to sleep-disordered breathing. Remember, Board decisions are not binding precedent on other veterans' claims. They only show how the Board weighed the evidence in front of it.
Grant where VA exam ignored documented sleep symptoms in the mental health record Citation A26018320 (March 2, 2026), Direct Review docket
The record: A June 2025 VA examiner found OSA "not medically related" to depression with GAD, saying the two conditions were separate entities and citing general OSA risk factors like weight, age, and smoking. A February 2025 private physician reviewed the file and explained that chronic stress and heightened arousal from anxiety and depression disrupt sleep architecture, leading to throat muscle relaxation and OSA. The private physician tied this to the veteran's specific stressors, including his service-connected shoulder condition feeding into his psychiatric symptoms.
Why it won: The Board found the June 2025 VA opinion failed to address an August 2024 mental health exam that documented the veteran's sleep disturbances and chronic sleep impairment. Because the VA examiner ignored this relevant evidence, the Board gave the opinion little weight. The private opinion, by contrast, gave "clear conclusions with supporting data" and reasoned medical explanations, so the Board gave it significant weight and granted the claim.
Grant based on a psychologist's literature-supported nexus statement Citation A26014699 (February 18, 2026), Hearing docket
The record: Two VA examiners (a physician in July 2019 and a physician assistant in November 2019) found the veteran's OSA was not related to her service-connected panic disorder and agoraphobia, pointing to her BMI and a "crowded oropharynx" as the mechanical cause. A private licensed psychologist, PhD F.W.N., reviewed the file, interviewed the veteran, and cited peer-reviewed studies linking anxiety and PTSD to higher rates of OSA. He also addressed the veteran's obesity in the context of her psychiatric and physical limitations.
Why it won: The Board found the July 2019 VA opinion did not consider whether obesity served as an "intermediate step" between the psychiatric disability and OSA. The November 2019 VA opinion did not address the veteran's anxiety and insomnia symptoms or the scientific literature on OSA and mental health. The psychologist's opinion did both, and he "adequately acknowledged his limitations as a licensed psychologist." The Board found his opinion persuasive and granted the claim.
Grant on an aggravation theory when two VA opinions never addressed aggravation Citation A26003558 (January 14, 2026), Evidence Submission docket
The record: A July 2022 VA examiner and a May 2024 VA examiner both found the veteran's OSA was not caused by his service-connected generalized anxiety disorder with major depressive disorder and alcohol use disorder in remission, citing smoking and unspecified "medical literature." A private physician assistant, L.M.B., reviewed the whole VA claims file, including the negative opinions, and explained in detail how psychiatric symptoms can contribute to or aggravate upper airway dysfunction, citing anatomical brain changes and the veteran's documented sleep impairments.
Why it won: The Board gave both VA opinions "minimal probative weight" because neither one addressed whether the psychiatric disability aggravated the OSA, and neither examiner specified the literature relied on. The private PA's opinion was based on a thorough review and cited specific literature, so the Board gave it great weight and granted the claim on an aggravation basis.
Grant where the VA opinions gave only conclusory statements Citation A26000610 (January 5, 2026), Evidence docket
The record: A December 2023 VA examiner said there was no in-service treatment and a time lapse before diagnosis. A February 2025 VA examiner said there was "no pathological or etiological correlation" between GAD and OSA. A private physician, Dr. S.B., opined that GAD sustains sympathetic nervous system hyperactivity that increases upper airway muscle tension and impairs airway patency, and also causes dysfunctional breathing patterns that destabilize breathing during sleep, citing supporting medical studies.
Why it won: The Board found the December 2023 opinion improperly relied on the absence of treatment records, and the February 2025 opinion gave only a "vague statement" without real analysis. Dr. S.B.'s opinion was "extensive and detailed," with multiple studies cited. The Board found this most probative and granted the claim.
Grant despite a competing claim theory, where the private nexus statement stood unopposed Citation A25106163 (December 9, 2025), Evidence Submission docket
The record: The veteran was diagnosed with moderate OSA. A physician assistant, L.B., submitted a private report stating it was "at least as likely as not" that the veteran's OSA was "secondarily linked to his service-connected mental health disability." No VA medical opinion on this specific nexus question was discussed in the decision.
Why it won: Because the veteran was pursuing secondary service connection, the Board explained he only needed to show that a current disability existed and that it was caused or aggravated by a service-connected condition. With the private PA's opinion establishing that link and no contrary opinion addressing it head-on, the Board resolved doubt in the veteran's favor and granted the claim.
What the Board Said in Recent Grants
These are the Board's own words, quoted from the findings in 5 recent granted decisions on this pairing. Each sentence is the finding the grant rested on, not a summary of it. Click a citation to read the full decision.
“The Veteran's OSA is due to service-connected depression (major depressive disorder) with generalized anxiety disorder.”
“Resolving reasonable doubt in the Veteran's favor, the evidence is at least in approximate balance that his current OSA is aggravated by his service-connected generalized anxiety disorder with recurrent major depressive disorder and alcohol use disorder in remission (psychiatric disability).”
“Resolving all doubt in the Veteran's favor, it is at least as likely as not that his obstructive sleep apnea was caused by his service-connected generalized anxiety disorder”
“The evidence of record is at least in approximate balance or nearly equal that the Veteran's sleep apnea condition is caused by his service-connected generalized anxiety disorder, major depressive disorder with alcohol use disorder”
“The evidence is approximately evenly balanced as to whether the Veteran's sleep apnea was caused by service-connected PTSD, generalized anxiety disorder, and major depression.”

Why VA Denies, and How the Board Answered
The rationales below are the ones VA examiners actually used against this pairing in the published record, each paired with the Board's response.
- Read the left column first: if a VA opinion in your file uses one of these arguments, that is the reasoning your own evidence has to meet.
- The right column is the counter: it shows how the Board actually answered that argument, with the decision cited.
- A rationale appearing here is not a verdict: the same argument won some cases and lost others, on different records.
| VA examiner's rationale | How the Board answered it |
|---|---|
| OSA is a mechanical or anatomical problem (airway collapse, crowded oropharynx, deviated septum), so anxiety or a related psychiatric condition cannot be the cause, and no scientifically controlled studies prove a causal link. | The Board found some of these opinions probative and adopted them where the examiner reviewed the whole file and gave a detailed explanation (A25002256, A23007125). But in other cases, the Board found the same type of reasoning conclusory when the examiner failed to address the veteran's own reported psychiatric sleep symptoms or discuss the medical literature on point (A24049712). |
| The veteran's obesity, not the psychiatric disability, is the true cause of OSA, and the record does not show the psychiatric disability or its medications caused the obesity in the first place. | The Board agreed obesity was the more likely explanation where the record showed major weight gain occurred before the anxiety diagnosis, and where private opinions used the wrong entrance weight or failed to explain why anxiety caused the weight gain (A24079995, A24058345). |
| Buddy statements describing snoring or breathing pauses during service do not prove sleep apnea existed at that time, especially when written years later and potentially subject to recall bias. | The Board found the buddy statements credible as observations of symptoms, but still found the VA opinion addressing them more probative overall, since the examiner explained why snoring alone is not evidence of OSA (A25002256). |
| A private opinion discusses general research linking anxiety, tinnitus, or a deviated septum to sleep apnea in populations generally, but this shows correlation, not an individualized causation analysis for this veteran. | The Board agreed and gave the private opinion little or no weight, finding it used "boilerplate language," failed to explain how the cited studies applied to the veteran's specific case, and even discussed a diagnosis (PTSD or TBI) the veteran did not have (A24049712, A24058345). |
| The veteran is not competent to link his own OSA to a service-connected psychiatric disability because the question requires specialized medical knowledge. | The Board agreed with this general principle in every denial reviewed here, and in each case decided the claim based on which competing medical opinion it found more probative, not on the veteran's own lay opinion (A24058345, A23007125). |
If Granted: How Sleep Apnea Is Rated
The VA assigns one of these percentages based on what your medical record documents. Plain-language summary of the rating criteria at 38 CFR; the controlling text is the regulation itself.
| Rating | What the record has to show for DC 6847, Sleep Apnea |
|---|---|
| 100% | You qualify at this level if your sleep apnea has caused chronic respiratory failure where your body can't get rid of carbon dioxide properly, or if it has led to cor pulmonale (heart problems caused by lung disease). You also qualify if you need a tracheostomy (a surgical opening in your neck to help you breathe). |
| 50% | You must use a breathing assistance machine like a CPAP device (continuous positive airway pressure machine) all the time to help keep your airways open and support your breathing. |
| 30% | You feel excessively sleepy during the day on a regular, ongoing basis that doesn't go away. This persistent daytime sleepiness (hypersomnolence) means you have trouble staying awake or alert during normal daytime hours, even after what should be a full night's sleep, and it significantly impacts your daily activities. |
| 0% | You have been diagnosed with sleep apnea through a sleep study or other medical testing, but you don't experience any noticeable symptoms from it. Even though the medical tests show you have breathing problems while sleeping (documented sleep disorder breathing), you don't have symptoms like daytime fatigue, morning headaches, or need to use a CPAP machine. |
Do's and Don'ts
Every item below comes from a pattern in the decisions on this pairing, not from general claim advice.
- Get a private opinion that reviews your full claims file, including any negative VA opinions, and explains specifically why those opinions fall short.
- Make sure your private doctor discusses your correct weight history and other individual facts, not just general population studies.
- Point out if a VA mental health exam documented sleep disturbance or chronic sleep impairment, since the Board has found sleep apnea opinions less credible when they ignore this.
- Ask your private examiner to address aggravation as well as causation, since some VA opinions only address whether the psychiatric condition caused the OSA outright.
- Keep and submit lay statements about snoring or breathing problems during service, since the Board has found these credible even when they do not decide the case alone.
- Don't rely on a private opinion that cites only general research about veterans as a "class" without tying the studies to your specific medical history.
- Don't submit an opinion built on the wrong entrance weight or other inaccurate facts, since the Board has thrown out opinions for this reason alone.
- Don't assume a buddy statement about snoring, by itself, proves you had sleep apnea in service.
- Don't submit an opinion that argues the reverse relationship (that your sleep apnea aggravated your psychiatric condition) if what you are claiming is that your psychiatric condition caused or aggravated your sleep apnea.
- Don't expect a private opinion diagnosing a condition you don't have (like PTSD or TBI, when you are only service connected for GAD) to carry weight with the Board.
Quick Checklist Before You File
- Service connection already in place for Anxiety Disorder, and a current medical diagnosis of sleep apnea.
- Diagnostic testing, imaging, or clinical records documenting the sleep apnea, whatever your provider used to diagnose and track it.
- A nexus opinion, whenever possible from a doctor familiar with sleep apnea, stating it is at least as likely as not caused or aggravated by the anxiety disorder, and naming the mechanism rather than just the conclusion.
- Lay statements: spouse, family, friends, or battle buddies describing what they've witnessed or noticed.
- Your STRs and any VA opinions already in the file on either condition. If a VA opinion already went against you, your submitted opinion or statement should address its specific reasoning.
For the mechanics of filing itself, see the Standard Claim Guide and the Fully Developed Claim Guide.
The Claims Process, Step by Step
A secondary claim moves through the same pipeline as any other. Understanding who does what helps you know who to contact and what to expect.
- You file the claim, naming Anxiety Disorder as the service-connected primary and sleep apnea as secondary. Directly with VA, through VA.gov, or with an accredited representative's help.
- VA assigns a Veteran Service Representative (VSR) to develop the claim: gather your service treatment records, VA and private medical records, and order a C&P exam if needed.
- The C&P exam is conducted, usually with the examiner asked to address the specific secondary theory (causation and aggravation both).
- The file goes to a Rating Veteran Service Representative (RVSR), the "rater," who weighs the medical evidence and decides service connection and, if granted, the rating percentage.
- VA issues the decision letter stating the outcome and the reasoning.
- If denied or under-rated, you choose an appeal lane, Supplemental Claim, Higher-Level Review, or a Board appeal, covered below.
Who's who: VSO vs. VSR vs. Rater vs. C&P Examiner
Your VSO
An accredited representative, agent, or attorney. Not a VA employee. Helps prepare and file, and can represent you on appeal. Has no authority to decide your claim.
VSR
VA staff who develops the claim: gathers records and schedules the exam. Does not decide the rating.
Rater (RVSR)
VA staff who reviews the complete file and makes the actual decision on service connection and percentage.
C&P Examiner
Conducts the exam and, where asked, gives a nexus opinion. Does not decide the claim, but the opinion's reasoning and legal framing carry real weight.
For the full walkthrough, see Inside Your Claim and Claim Stages.
DBQs and Your C&P Exam
A Disability Benefits Questionnaire (DBQ) is the standardized form the examiner completes for your condition. See the DBQ Guide for how these forms work and whether a private DBQ from your own doctor can be submitted instead of relying solely on a VA exam. For what to expect and how to prepare, see the C&P Exam Prep Guide, and be specific about how your sleep apnea symptoms relate to your anxiety disorder timeline, treatment, and any aggravation, that is the detail a nexus opinion relies on.
Reading Your Decision Letter, and What to Do If Denied
Your decision letter has a narrative "reasons and bases" section and a codesheet with the rating and effective date. See the Reading Your Decision Letter Guide or use the Letter Interpreter tool to decode your own letter. If denied, you have three main lanes:
- Supplemental Claim: refile with new and relevant evidence, such as a nexus opinion that addresses the mechanism and the specific VA rationale you're rebutting. See Supplemental Claim Guide.
- Higher-Level Review (HLR): a senior reviewer looks at the same evidence again, useful if the denial rested on a legal error. See HLR Guide.
- Board Appeal: your case goes to a Veterans Law Judge, with a direct review, evidence, or hearing docket. See Board Appeal Guide.
Not sure which lane fits? See the Appeals decision guide for a side-by-side comparison.
After You Win: Maintaining Your Rating
Keep documentation of ongoing treatment, follow-up evaluations, and any updated diagnostic testing for your sleep apnea on file, this protects you if VA schedules a future reexamination. See Protect Your Rating for when a rating becomes protected and Future Reexaminations for what triggers one. If your sleep apnea worsens, see the Rating Increase Guide.
Frequently Asked Questions
Does Anxiety Disorder have to be highly rated to support a sleep apnea secondary claim?
No. 38 CFR 3.310 looks at whether the service-connected Anxiety Disorder caused or aggravated the sleep apnea, not at how severe the Anxiety Disorder rating is. Even a 0% service-connected primary can anchor a secondary claim.
What do the percentages on this page mean?
They are the historical outcomes of 213 published Board decisions on this exact pairing: 30% granted, 23% denied, 45% remanded. They describe decided appeals already on record. They do not predict what would happen in any individual case.
