VA Disability Rating for Sleep Apnea: A Complete Guide (2026)

If you were prescribed a CPAP machine after service and told your sleep apnea might be connected to your time in the military, you are far from alone. Sleep apnea has become one of the most commonly claimed VA disabilities, and it is also one of the most misunderstood, since the rating depends less on how tired you feel and more on a specific piece of medical equipment sitting on your nightstand.

This guide explains how VA currently rates sleep apnea under Diagnostic Code 6847, a proposed 2026 change that has not yet taken effect, what evidence establishes service connection, the most common reasons sleep apnea claims get denied, and why the quality of your nexus letter matters as much as your sleep study results.

What Counts as a VA-Ratable Sleep Apnea Diagnosis

Obstructive sleep apnea is the most commonly claimed form, but VA rates all forms of sleep-disordered breathing, including central and mixed sleep apnea, under the same diagnostic code once a qualified sleep study confirms the diagnosis. A polysomnogram, whether performed in a lab or at home, is generally required to establish the diagnosis in the first place.

What makes sleep apnea different from most other VA claims is that the rating schedule does not scale with symptom severity the way conditions like back pain or PTSD do. Instead, it largely turns on whether you have been prescribed a specific treatment.

How VA Rates Sleep Apnea Under Diagnostic Code 6847

VA rates sleep apnea using four percentage tiers, and unlike most musculoskeletal or mental health conditions, the middle tier is defined by treatment rather than symptoms alone.

100 percent: Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or the condition requires a tracheostomy. This tier is reserved for severe, rare cases involving serious downstream cardiopulmonary complications.

50 percent: Requires the use of a breathing assistance device such as a CPAP machine. This is the most commonly awarded rating, since the large majority of veterans with a confirmed diagnosis are prescribed a CPAP or similar device as first-line treatment.

30 percent: Persistent daytime hypersomnolence, meaning excessive daytime sleepiness that occurs without a prescribed breathing assistance device. Veterans who have a confirmed diagnosis but have not yet been prescribed a CPAP, or who decline to use one, often fall into this tier.

0 percent: Asymptomatic but with documented sleep disorder breathing. This tier establishes service connection and the diagnosis on your record without a monthly payment attached.

For 2026, following the 2.8 percent cost-of-living adjustment that took effect December 1, 2025, a veteran with no dependents receives $552.47 per month at 30 percent, $1,132.90 per month at 50 percent, and $3,938.58 per month at 100 percent.

A Note on the Proposed 2026 CPAP Rule Change

VA has proposed rewriting Diagnostic Code 6847 to move away from the current standard, under which prescribing a CPAP alone triggers a 50 percent rating, toward a treatment-effectiveness standard that would look at how well the device actually controls the condition rather than simply whether one was prescribed. This proposal has not been finalized, and any change would not reduce ratings already in place, since VA is required to protect existing ratings from being cut solely because the rating schedule itself changed. Claims filed today are still decided under the current CPAP-based standard described above.

What Evidence Establishes Service Connection for Sleep Apnea

A sleep apnea claim generally rests on three pieces of evidence working together.

A current diagnosis confirmed by a sleep study. A polysomnogram showing an elevated apnea-hypopnea index is the objective foundation VA looks for, along with a prescription for a CPAP or other treatment if one has been issued.

An in-service event or a qualifying secondary connection. Direct service connection requires evidence the condition began in or was aggravated by service, which can be difficult for a condition often diagnosed years after separation. Far more sleep apnea claims succeed as secondary claims, connected to an already service-connected condition such as PTSD, a deviated septum from an in-service injury, or weight gain caused by a service-connected orthopedic condition that limits exercise.

A medical nexus opinion. A provider needs to state, using VA's "at least as likely as not" standard, that the sleep apnea is connected to service directly or was caused or aggravated by an already service-connected condition. Given how often sleep apnea is claimed secondarily, this opinion is frequently the entire case.

Common Reasons Sleep Apnea Claims Get Denied

Sleep apnea claims fail for a recurring set of avoidable reasons.

No sleep study in the file. Without a polysomnogram confirming the diagnosis, VA has no objective basis to grant the claim no matter how compelling the veteran's description of symptoms.

Weak or missing secondary nexus evidence. Many veterans correctly suspect their sleep apnea developed because of weight gain tied to a service-connected knee, back, or mental health condition, but never get a provider to connect those dots in writing using VA's required language.

Obesity treated as an intervening cause. Raters sometimes deny secondary sleep apnea claims by attributing the weight gain to lifestyle rather than to the service-connected condition that limited the veteran's ability to stay active. A well-supported nexus letter needs to address this directly.

No documentation of CPAP compliance. Veterans who were prescribed a CPAP but have limited records showing ongoing use sometimes see their rating challenged at a later review, since the 50 percent tier is tied to the prescription and its ongoing medical necessity.

Why the Nexus Letter Is Critical for Sleep Apnea Claims

Because so many sleep apnea claims succeed or fail on a secondary connection rather than a direct one, the nexus letter often carries more weight here than for conditions with an obvious in-service injury.

A strong nexus letter for a sleep apnea claim should:

• Identify whether the claim is direct or secondary, and name the specific service-connected condition believed to have caused or aggravated the sleep apnea

• State a clear medical opinion using the "at least as likely as not" language VA raters are trained to look for

• Reference the sleep study findings and any CPAP prescription supporting the current diagnosis

• Explain the physiological reasoning connecting a secondary condition, such as weight gain from reduced mobility or medication side effects, to the development of sleep apnea

• Be written by a licensed medical provider who has reviewed the claims file and treatment history, not a generic template with a name inserted

A letter that only states "the veteran has sleep apnea that may be related to service" gives VA nothing to act on, particularly for a secondary claim where the entire theory of the case depends on a documented physiological chain. A letter that walks through that chain step by step gives a rater a clear, defensible basis to grant service connection.

Get Your Records Reviewed at No Cost

If you have sleep apnea and are not sure whether your evidence supports a direct or secondary claim, or whether your sleep study and treatment records are strong enough to withstand review, the fastest way to find out is to have your records reviewed before you file or appeal.
