Sleep apnea involves disrupted breathing during sleep. Diagnostic Code 6847 is commonly used for sleep apnea syndromes in VA claims. Ratings often depend on whether the veteran requires a breathing assistance device and how symptoms affect daytime function, as described in 38 CFR and summarized here in plain language.
Rating criteria current as of 2026-04-01 (verify against the live eCFR).
Regulatory change notice: The VA has proposed significant changes to sleep apnea rating criteria under DC 6847. The proposed rule would eliminate the current 30 percent level, revise the 50 percent criteria (no longer tied solely to CPAP use), and add new requirements related to treatment effectiveness. As of early 2026 the rule has not been finalized. Veterans with existing ratings are expected to be grandfathered at their current level. Always verify the live eCFR for the version in effect for your claim.
Overview and military service context
Weight change, nasal trauma, deployment sleep disruption, and PTSD related sleep problems sometimes appear in the same health history as sleep apnea. Service connection questions are separate from rating. This page explains how the VA typically applies DC 6847 after apnea is in the claim file.
What Diagnostic Code 6847 covers
DC 6847 addresses obstructive, central, and mixed sleep apnea syndromes under the schedule for respiratory conditions. The percentage levels focus on documented breathing events during sleep, objective sleep testing, prescribed therapy, and severe outcomes such as chronic respiratory failure when those criteria appear in the regulation.
Rating levels in structured form (educational summary)
Read 38 CFR 4.97 and DC 6847 for exact wording. The table below is a study guide.
| Percentage | Plain language theme tied to the schedule |
|---|---|
| 100 percent | Chronic respiratory failure with carbon dioxide retention, cor pulmonale, or need for tracheostomy as described in the regulation |
| 50 percent | Requires use of a breathing assistance device such as continuous positive airway pressure (CPAP) when the regulatory conditions for that step are met |
| 30 percent | Persistent daytime hypersomnolence under the regulatory definition |
| 0 percent | Documented sleep disordered breathing that is asymptomatic, that is, no daytime symptoms meeting the higher levels |
If your decision uses different words, trust the decision’s citation to the version of 38 CFR in effect for your case.
How polysomnography fits the file
A sleep study measures apneas, hypopneas, oxygen drops, and sleep stages. The VA often looks for a valid diagnosis from an acceptable study. Home sleep tests and in lab polysomnography each have clinical rules. Bring complete reports rather than only a one line summary when you gather records for personal organization.
CPAP compliance data and medical judgment
Many veterans receive CPAP therapy. The 50 percent step in DC 6847 references required use of a breathing assistance device when regulatory conditions are satisfied. Compliance reports from machines may appear in records. Medical providers also document whether therapy is indicated and tolerated. This page does not tell anyone how to use a device; it explains why those records surface in rating discussions.
Daytime sleepiness and the 30 percent step
Persistent daytime hypersomnolence is a regulatory phrase. Clinicians may document Epworth scores, nap frequency, or work safety concerns. The rater compares those findings to the schedule language. Migraines and other conditions can cause fatigue too, so clear symptom attribution in notes helps readers.
Higher severity respiratory outcomes
The 100 percent level speaks to severe respiratory failure patterns or tracheostomy need as written in the regulation. Those outcomes are less common in routine apnea claims but matter when the evidence shows them.
Evidence and documentation veterans often collect
Sleep study reports, pulmonology or sleep clinic notes, CPAP settings, weight trends, and hospitalizations for respiratory issues can appear in strong files. Lay statements about witnessed apneas or gasping help tell a story but may pair best with objective testing.
C and P examination ideas for sleep apnea
Examiners may review study summaries, ask about daytime sleepiness, and discuss therapy use. Bring a medication list and any recent sleep clinic letters. If you also have ringing ears, see tinnitus for how DC 6260 differs.
Secondary relationships in educational terms
Some veterans explore apnea as secondary to PTSD or weight gain related to mental health medication. Medical nexus opinions vary in quality. This site does not predict whether secondary service connection will be granted.
Overlap with mental health and headaches
PTSD can disturb sleep architecture. Migraines can worsen with poor sleep. Multiple conditions can be service connected when evidence supports each. Pyramiding rules prevent double payment for the same symptom under duplicate codes.
Weight, fitness, and clinical care
Providers often discuss weight management as part of apnea care. Lifestyle topics belong with clinicians. Ratings follow DC 6847 criteria rather than body weight alone.
Aviation, commercial driving, and safety sensitive jobs
Daytime sleepiness can affect occupational medical clearances. Those are employer and licensing issues outside VA rating math, yet they explain why veterans sometimes prioritize treatment even while a claim is pending.
Children and bed partners as lay observers
Partners may describe snoring or breathing pauses. Lay statements are one type of evidence. Objective studies usually anchor the diagnosis.
Central sleep apnea and mixed patterns
Not every apnea claim is classic obstructive disease. Cardiology and neurology notes sometimes explain central components. Accurate labels in the record help raters pick the right schedule discussion.
When a study is old
If years pass since the last sleep test, the VA may order a new exam for an increased rating claim. Technology and symptoms change. A fresh study can show current severity.
Dental appliances and positional therapy
Some treatments are not CPAP. Whether a therapy counts as a breathing assistance device for DC 6847 is a legal and medical detail read from the regulation and facts. Ask accredited representatives when specifics differ.
Deployment sleep debt versus apnea
Short term sleep loss in training differs from chronic disordered breathing. Clinicians sort causes. The claim file should reflect that sorting.
Hypertension and cardiac comorbidity
Sleep apnea can travel with blood pressure issues. Those may be separate claims or risk factors documented in charts. Rating for apnea still follows DC 6847.
Appeals literacy
Compare the decision’s summary of your sleep study to the actual report pages. If the rater misread AHI numbers or therapy status, review options exist. This page does not provide appeal tactics.
Combined rating practice
Use /calculator to model DC 6847 with tinnitus or knee style conditions for educational math.
Pediatric family context
Veterans who are parents may note child interrupted sleep; focus stays on the veteran’s own diagnosis and symptoms for the claim file.
Research versus regulation
New home monitoring gadgets appear often. VA decisions rely on acceptable medical evidence under law and policy, not on consumer device marketing.
Medication side effects
Sedating medicines can worsen daytime sleepiness documentation. Accurate med lists help examiners interpret symptoms.
Climate, altitude, and travel
Some veterans notice apnea therapy needs change with altitude or allergies. Clinical notes can mention adjustments. Those details rarely replace core DC 6847 steps but can explain trends.
Why decisions quote therapy adherence
When 50 percent hinges on prescribed device use, decisions may discuss adherence reports. If therapy was attempted but not tolerated, the file may include alternative plans from a provider.
Strengthening personal organization
Keep PDFs of sleep studies with date and facility on the file name. Store CPAP summary cards from durable medical equipment companies when available.
Mental health treatment timing
If PTSD care intensified before a sleep study, timelines help clinicians and raters understand context without blending distinct conditions.
Split night studies and titration nights
Some labs diagnose apnea on the first half of the night then start pressure trials on the second half. Reports label those sections clearly. When you read your own PDF, look for total events per hour and oxygen nadir values your clinician explained.
Insurance denials and record gaps
Private insurers sometimes decline first sleep studies. If a VA study later exists, the file may jump across facilities. A short chronology you keep for yourself can help representatives see the order of events without digging through hundreds of pages.
Veterans who travel for work
Frequent travel can disrupt CPAP routines. Download data when your machine allows before appointments so clinicians see recent weeks rather than guessing.
Firefighters, shift workers, and circadian overlap
Shift work disorder can muddy daytime sleepiness stories. Sleep medicine clinicians sometimes separate shift issues from apnea hypersomnolence. Accurate labels help DC 6847 analysis.
Post deployment weight changes
Body weight changes after separation appear in many records. Apnea severity can change with weight. An increased rating claim might include a newer study showing worse metrics even if service connection started years earlier.
Surgical options in general terms
Some patients discuss uvulopalatopharyngoplasty or hypoglossal nerve stimulators with surgeons. Surgical paths are medical decisions. Decisions discuss what the evidence shows about ongoing severity and therapy requirements after procedures.
Allergic rhinitis and nasal obstruction
Nasal blockage can worsen apnea for some people. ENT notes about septum or turbinates sometimes appear alongside sleep clinic letters. Those notes may relate to treatment planning more than to a separate VA code unless another condition is claimed.
Smoking history documentation
Smoking can affect airway inflammation. Honest history helps clinicians. This page does not moralize; it notes that charts often capture pack years for context.
Oxygen at night versus CPAP
Nocturnal oxygen orders appear for some patients. Whether an oxygen order maps to the same schedule step as CPAP is a legal detail tied to wording in 38 CFR. Representatives read those fine points with the full decision.
Bed partner mental health
Partners may lose sleep too. Their lay statements sometimes describe observable events. Focus stays on the veteran’s diagnosis for the VA claim, but family impact can be real life context.
Children and co sleeping safety
Pediatric safety guidance exists for family beds. Medical providers give household advice. This educational page does not give parenting medical instructions.
When apnea is mild on paper but symptoms feel severe
Sometimes AHI numbers look low while subjective sleep quality is poor. Clinicians explore other sleep disorders such as insomnia or limb movements. The rating schedule for DC 6847 still keys off regulatory findings rather than frustration alone.
Academic performance for veterans in school
Daytime sleepiness can affect classes. School accommodations are separate systems. Still, academic records occasionally appear when veterans explain functional impact.
Commercial pilots and FAA medical rules
Aviation medical certification has strict sleep apnea protocols. VA rating and FAA certification are different agencies with different questions.
CPAP mask types and comfort trials
Full face, nasal, and pillow masks fit different faces. Durable medical equipment teams document mask trials. Those notes show good faith treatment attempts even when comfort was hard at first.
Humidification and dry airway symptoms
Heated humidifiers reduce dryness for some users. Machine settings belong in clinical notes when relevant.
Power outages and travel adapters
Practical barriers to therapy exist for some households. Social workers or clinics sometimes help problem solve. Those stories may appear as personal statements but do not replace medical need findings.
When a veteran declines therapy
Personal choice and medical contraindications differ. Decisions may discuss whether a prescribed device was medically indicated and whether the record supports a schedule step without it. This page does not judge choices; it flags why that fact pattern can be legally complex.
Research on apnea and cognition
Studies link apnea to attention issues. Cognitive testing may appear in TBI or mental health files. TBI has a different diagnostic code. Keep issues distinct when reading decisions.
Reading fine print on sleep study headers
Check whether the study is diagnostic, split, or titration. Labels change how clinicians interpret numbers. When a decision quotes one line from a long PDF, open the same page to confirm context.
