Sleep Apnea Secondary to Anxiety

Overview

Obstructive sleep apnea (OSA) is a condition in which the upper airway repeatedly narrows or collapses during sleep, interrupting breathing and fragmenting sleep. Veterans with service-connected anxiety disorders sometimes claim it as secondary. VA can grant that claim, but only on medical evidence, because OSA has strong risk factors of its own: excess weight, age, male sex, and airway anatomy.

The honest picture is that anxiety and OSA frequently occur together, and each can worsen the other. The theories most likely to succeed are specific and documented, such as weight gain from a psychiatric medication. Aggravation theories also work when the record supports them. General statements that anxiety “affects breathing” rarely carry a claim.

VA rates sleep apnea under Diagnostic Code 6847, in the respiratory system. A grant combines with your mental-health rating rather than overlapping it.

What the Research Shows

• They often coexist, in both directions. A 2020 meta-analysis of 73 studies (Garbarino et al., Behavioral Sleep Medicine) found anxiety symptoms in about 32% and depressive symptoms in about 35% of people with OSA. The authors described the relationship as probably bidirectional. Untreated OSA can worsen anxiety, which is one reason the timeline in your records matters.
• Medications. Some psychiatric medications, such as certain antipsychotics (for example, quetiapine) and mirtazapine, are known to cause weight gain, a major OSA risk factor. For sedatives, the evidence is more reassuring than often claimed. A Cochrane review of small, short trials (Mason et al., 2015) found that the hypnotics and sedatives studied, including several benzodiazepines, did not significantly increase apnea severity (AHI). Some did lower minimum overnight oxygen saturation. The authors urged caution because the trials were small.
• Mechanisms. Hyperarousal and fragmented sleep have been proposed as contributors, but direct evidence that anxiety causes airway collapse is limited.

Theories That Hold Up Best

1. Medication-related weight gain (intermediate step). VA’s General Counsel (VAOPGCPREC 1-2017) held that obesity can be an intermediate step between a service-connected condition and a secondary one. The adjudicator must find three things: (1) the anxiety disorder, or its treatment, caused the weight gain; (2) the weight gain was a substantial factor in causing OSA; and (3) OSA would not have occurred without it. Prescription start dates and weight records before and after are the key evidence.
2. Aggravation. If you already had OSA, the question is whether the anxiety disorder or its treatment worsened it beyond natural progress. For example, anxiety or claustrophobia may prevent effective CPAP use. Aggravation needs evidence of the baseline severity, such as an earlier sleep study (38 CFR 3.310(b)).
3. Direct causation. This theory is supported mainly by association. It needs a specialist’s reasoned explanation tied to your history.

How VA Decides the Claim

• Causation (38 CFR 3.310(a)) and aggravation (38 CFR 3.310(b)) must be addressed separately. An opinion that addresses only causation is inadequate (El-Amin v. Shinseki, 26 Vet. App. 136 (2013)).
• VA must consider every theory reasonably raised, including direct service connection if your symptoms began in service.

Evidence Requirements

• Sleep study diagnosis of OSA, with the apnea-hypopnea index (AHI).
• Service-connected anxiety disorder. Your rating decision.
• Medication history with start dates and doses, and weight history, if you are using the weight-gain theory.
• A medical opinion from a sleep physician, pulmonologist, or psychiatrist that applies these facts, addresses causation and aggravation separately, and deals with other risk factors.
• CPAP prescription and usage data, which are relevant to the 50% level.
• Lay statements from a bed partner about snoring, gasping, or pauses, and when they began.

Rating Criteria for Sleep Apnea

Sleep apnea is rated under DC 6847 (38 CFR 4.97). These are the current criteria:

0% Rating

Asymptomatic but with documented sleep disorder breathing.

30% Rating

Persistent daytime hypersomnolence.

Monthly compensation at 30% (single veteran, no dependents, 2026): $552.47

50% Rating

Requires use of a breathing assistance device such as a continuous airway pressure (CPAP) machine.

Monthly compensation at 50% (single veteran, no dependents, 2026): $1,132.90

100% Rating

Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or requires tracheostomy.

Proposed change. VA proposed replacing these criteria in 2022. The proposal has not been finalized, and the criteria above remain in effect. See our update on the proposed sleep apnea rating changes.

How to File This Secondary Claim

1. Get a sleep study if you do not have a diagnosis.
2. Confirm your anxiety disorder is service connected.
3. Gather the facts behind your theory, especially medication dates and weight records.
4. Get a medical opinion that applies those facts and addresses causation and aggravation separately.
5. File VA Form 21-526EZ on VA.gov, listing sleep apnea as secondary to your anxiety disorder, and upload your evidence with the claim.
6. Attend the C&P exam.

C&P Exam Tips

• Bring your sleep study report and CPAP usage data.
• Describe your symptoms accurately: daytime sleepiness, morning headaches, witnessed breathing pauses, and how often each happens.
• Explain the timeline: when anxiety treatment started, which medications, when your weight changed, and when apnea symptoms were first noticed.
• Describe typical days and bad days, and say which is which.

Impact on Combined Rating

VA combines ratings with the 38 CFR 4.25 combined ratings table.

Example 1: Anxiety 50% + sleep apnea 50%

1. 50% combined with 50% = 75
2. 75 rounds up to 80%

Example 2: Anxiety 30% + sleep apnea 50%

1. 50% combined with 30% = 65
2. 65 rounds up to 70%
