DC 6847 Sleep Apnea Diagnostic Code
50% Automatic w/ CPAP Use
38 CFR 4.97 Respiratory Schedule
1 Rating Per Respiratory System (4.96a)

Respiratory conditions — especially sleep apnea — are among the highest-impact claims a veteran can file. A single sleep apnea claim that ends in a CPAP prescription automatically rates at 50% under current rules, instantly worth over $13,500 per year tax-free. When combined with PTSD or other conditions, it pushes combined ratings dramatically higher.

This guide walks through every respiratory rating under 38 CFR § 4.97: sleep apnea, asthma, COPD, emphysema, chronic bronchitis, sinusitis, and rhinitis. We'll cover the diagnostic codes, the evidence that wins, the upcoming proposed rule changes that may reshape sleep apnea ratings, and how to handle the C&P exam.

💡 Key Takeaway Under the current 2026 rating criteria, sleep apnea (DC 6847) requiring a CPAP machine automatically rates at 50%. The VA has proposed rule changes that may tie future ratings to treatment effectiveness rather than CPAP use alone — but no final rule has been issued. Claims filed under current rules remain rated under those rules.

01
How the VA Rates Sleep Apnea (DC 6847)

Sleep apnea is rated under 38 CFR § 4.97, Diagnostic Code 6847 (Sleep Apnea Syndromes — Obstructive, Central, Mixed). Unlike most VA conditions with subjective severity descriptions, sleep apnea ratings have clear-cut criteria with four distinct tiers:

Rating Criteria 2026 Monthly Pay (Veteran Alone)
0% Asymptomatic but with documented sleep disorder breathing (diagnosed by sleep study) $0 — non-compensable, but service connection preserved
30% Persistent daytime hypersomnolence (excessive daytime sleepiness) $552.47
50% Requires use of breathing assistance device such as a CPAP machine $1,132.90
100% Chronic respiratory failure with carbon dioxide retention OR cor pulmonale OR requires tracheostomy $3,938.58

The vast majority of veterans with diagnosed sleep apnea fall into the 50% tier because CPAP is the standard treatment for moderate-to-severe obstructive sleep apnea.

02
Why CPAP Triggers an Automatic 50%

The current rule is binary: if your doctor prescribes a CPAP machine and you use it, you qualify for 50%. The VA does not look at:

  • Your AHI (Apnea-Hypopnea Index) score
  • The severity of your apnea episodes
  • How much the CPAP helps
  • Whether you use the CPAP every night vs. occasionally

The question is binary: does the veteran require a breathing assistance device? If yes, 50%.

ℹ️ What Counts as a Breathing Assistance Device CPAP (Continuous Positive Airway Pressure), BiPAP (Bilevel Positive Airway Pressure), APAP (Auto-adjusting Positive Airway Pressure), and oral appliances prescribed as treatment for sleep apnea all qualify. The key requirement is a prescription from a physician — buying an over-the-counter mouthpiece doesn't count.

Evidence Needed for the 50% Rating

  • A formal sleep study (polysomnography) confirming sleep apnea diagnosis
  • Physician prescription for CPAP or other breathing assistance device
  • CPAP compliance data showing regular use (helpful but not strictly required)
  • Provider notes documenting symptoms and CPAP necessity

03
Establishing Service Connection for Sleep Apnea

Sleep apnea can be service-connected through three pathways:

1

Direct Service Connection

Symptoms began during service, or service treatment records document snoring, fatigue, witnessed apneas, or other sleep-disordered breathing during active duty. A nexus letter is typically required unless symptoms are clearly documented in your STRs.

2

Secondary Service Connection

Sleep apnea caused or aggravated by another service-connected condition — PTSD, depression, chronic pain, TBI, asthma, GERD, or sinusitis. This is often the easiest pathway for veterans diagnosed years after service.

3

Presumptive Service Connection

For veterans with qualifying exposures under the PACT Act, sleep apnea can be presumptively service-connected when associated with airway-related conditions caused by burn pits, particulate matter, or other recognized exposures.

04
Sleep Apnea as a Secondary Condition

For most veterans diagnosed with sleep apnea years after service, the secondary connection pathway is the strongest. The medical literature firmly supports the link between sleep apnea and many service-connected conditions:

🧠
Secondary to PTSD
Disrupted sleep architecture, hyperarousal, hypervigilant sleep positioning, and PTSD medication-induced weight gain all contribute to sleep apnea.
😢
Secondary to Depression
SSRI/SNRI weight gain, reduced activity, and altered sleep patterns drive sleep apnea development.
🦴
Secondary to Chronic Pain
Pain medications (opioids, gabapentin) affect respiratory drive. Reduced physical activity and weight gain contribute.
👃
Secondary to Sinusitis/Rhinitis
Chronic upper airway inflammation and obstruction directly cause or worsen obstructive sleep apnea.

05
Proposed 2026 Rule Changes

The VA published a Notice of Proposed Rulemaking on February 15, 2022, and a Supplemental Notice on September 12, 2024, proposing significant changes to sleep apnea ratings. The proposed approach would shift away from CPAP use as an automatic rating trigger and toward treatment effectiveness and functional impairment.

Important: as of May 2026, these remain proposed rules. No final rule or effective date has been issued. Sleep apnea continues to be rated under the existing 38 CFR § 4.97, DC 6847 criteria.

Key takeaways:

  • Claims filed and rated under current rules remain rated under those rules
  • If you're considering filing, current rules may be more favorable than the proposed rules
  • The proposed rules would consider comorbid conditions, treatment tolerance, and end-organ damage
  • CPAP compliance data is becoming more important regardless of which rules apply
⚠️ If You're Considering Filing Consult with a VSO or accredited representative about the current vs. proposed rules. Many veterans benefit from filing under current rules while they remain in effect. Documentation of CPAP necessity and consistent compliance protects your rating regardless of which rules ultimately apply.

06
Asthma VA Ratings (DC 6602)

Asthma is rated under Diagnostic Code 6602 (Bronchial Asthma). The rating is based on either pulmonary function test (PFT) results — specifically FEV-1 and FEV-1/FVC ratios — OR on the frequency and severity of asthma attacks and medication requirements.

Rating Criteria (PFT or Symptom-Based)
10% FEV-1 71–80% predicted, OR FEV-1/FVC 71–80%, OR intermittent inhalational/oral bronchodilator therapy
30% FEV-1 56–70% predicted, OR FEV-1/FVC 56–70%, OR daily inhalational/oral bronchodilator therapy, OR inhalational anti-inflammatory medication
60% FEV-1 40–55% predicted, OR FEV-1/FVC 40–55%, OR at least monthly visits to a physician for required care of exacerbations, OR intermittent (at least 3 per year) courses of systemic (oral or parenteral) corticosteroids
100% FEV-1 <40% predicted, OR FEV-1/FVC <40%, OR more than one attack per week with episodes of respiratory failure, OR daily use of systemic high-dose corticosteroids or immuno-suppressive medications

07
COPD, Emphysema & Chronic Bronchitis

These obstructive lung diseases are rated under similar PFT-based criteria:

  • DC 6604 — Chronic Obstructive Pulmonary Disease (COPD)
  • DC 6603 — Emphysema
  • DC 6600 — Chronic Bronchitis

Ratings range from 10% to 100% based primarily on:

  • FEV-1 (Forced Expiratory Volume in 1 second) — the most important measurement
  • FEV-1/FVC ratio — degree of airflow obstruction
  • DLCO (Diffusing Capacity for Carbon Monoxide) — gas exchange efficiency
  • Maximum oxygen consumption in advanced cases

The 100% rating typically requires FEV-1 below 40% predicted, severe exercise limitation, cor pulmonale, or chronic respiratory failure with continuous oxygen therapy.

Veterans with burn pit exposure under the PACT Act may qualify for presumptive service connection for COPD, asthma, emphysema, and several other respiratory conditions without needing a nexus letter.

08
Sinusitis & Rhinitis Ratings

Sinusitis (DC 6510–6514)

Chronic sinusitis is rated based on the frequency and severity of "incapacitating episodes" (requiring antibiotic treatment of 4–6 weeks) and "non-incapacitating episodes" (sinus pain, headaches, purulent discharge, crusting).

  • 0%: Detected by X-ray only
  • 10%: 1–2 incapacitating episodes per year, OR 3–6 non-incapacitating episodes per year
  • 30%: 3+ incapacitating episodes per year, OR 6+ non-incapacitating episodes per year
  • 50%: Following radical surgery with chronic osteomyelitis, OR near-constant sinusitis with debilitating symptoms after repeated surgery

Allergic or Vasomotor Rhinitis (DC 6522)

  • 10%: Without polyps but with greater than 50% obstruction of nasal passage on both sides or complete obstruction on one side
  • 30%: With polyps

09
The Predominant Disability Rule (38 CFR § 4.96a)

One of the most important rules for respiratory veterans: under 38 CFR § 4.96(a), you generally cannot receive separate ratings for multiple respiratory conditions that affect the same body system. Instead, the VA rates the predominant disability — the one with the highest evaluation under its rating schedule.

Conditions Subject to the Single-Rating Rule

The following respiratory conditions cannot receive separate ratings — only one is assigned at the predominant level:

  • Asthma (DC 6602)
  • Sleep apnea (DC 6847)
  • COPD (DC 6604)
  • Chronic bronchitis (DC 6600)
  • Emphysema (DC 6603)
  • Bronchiectasis (DC 6601)

If you have both asthma and sleep apnea, for example, the VA will rate whichever scores higher under its individual schedule — not both. This is a critical strategic consideration when filing multiple respiratory claims.

10
The Respiratory C&P Exam

Respiratory C&P exams typically involve:

  • Pulmonary function testing (PFT) — spirometry measuring FEV-1, FVC, FEV-1/FVC ratio, sometimes DLCO
  • Sleep study results review for sleep apnea cases (the examiner reads your polysomnography report)
  • Disability Benefits Questionnaire (DBQ) covering symptom severity, treatment, medications, and functional impact
  • Physical exam — lung auscultation, oxygen saturation, occasionally chest X-ray review

What the Examiner Will Ask

  • Frequency of attacks, exacerbations, or symptom episodes
  • Medications and dosages (inhalers, oral steroids, immunosuppressants)
  • Hospitalizations, ER visits, physician visits for the condition
  • CPAP prescription and compliance (for sleep apnea)
  • Functional impact on work, exercise, daily activities
  • Oxygen requirement (for severe cases)

Frequently Asked Questions

Sleep apnea is rated under 38 CFR § 4.97, Diagnostic Code 6847, at four levels: 0% (asymptomatic but diagnosed), 30% (persistent daytime hypersomnolence), 50% (requires CPAP or other breathing assistance device), or 100% (chronic respiratory failure with CO2 retention, cor pulmonale, or tracheostomy required). Most veterans with diagnosed obstructive sleep apnea using CPAP rate at 50%.
Under current rules, yes. If your sleep apnea is service-connected and your doctor prescribes a CPAP machine, the VA assigns a 50% rating regardless of AHI score, symptom severity, or compliance percentage. The VA has proposed changes to this rule, but as of May 2026, no final rule has been issued and current criteria apply.
Yes — and this is one of the strongest secondary claims. Medical literature supports connections between PTSD and sleep apnea through disrupted sleep architecture, hyperarousal, PTSD-medication-induced weight gain, and hypervigilant sleep positioning. You'll need a current sleep study, CPAP prescription, and a nexus letter from a sleep specialist or qualified provider linking your sleep apnea to PTSD.
Asthma is rated under DC 6602 at 10%, 30%, 60%, or 100% based on pulmonary function test results (FEV-1, FEV-1/FVC) OR the frequency of attacks and medication requirements. The 60% rating typically requires monthly physician visits or 3+ courses of systemic corticosteroids per year. The 100% rating requires FEV-1 below 40% predicted or more than one attack per week with episodes of respiratory failure.
Generally no. Under 38 CFR § 4.96(a), the VA cannot assign separate ratings for asthma (DC 6602) and sleep apnea (DC 6847) — instead, it rates the predominant disability (the higher of the two evaluations). The same rule applies to combinations of COPD, emphysema, chronic bronchitis, and bronchiectasis.
Yes — under the PACT Act of 2022, many respiratory conditions are presumptively service-connected for veterans exposed to burn pits and airborne hazards during qualifying service periods and locations. This includes asthma, COPD, chronic bronchitis, emphysema, certain cancers, and other airway-related conditions. No nexus letter is required for PACT Act presumptive claims.
A formal sleep study (polysomnography) is required to establish diagnosis. For a 50% rating, you also need a CPAP prescription. Strong claims also include CPAP compliance data, treatment records, a nexus letter (especially for secondary claims), lay statements from family or partners describing witnessed apneas and snoring, and a DBQ from your sleep specialist.
