Avoiding Pyramiding in Respiratory VA Claims: What Veterans Must Know

Quick Answer

The VA prohibits separate ratings for most coexisting respiratory conditions under 38 C.F.R. § 4.96(a), meaning conditions like asthma (DC 6602) and sleep apnea (DC 6847) cannot be rated separately . Instead, the VA assigns a single rating based on the predominant disability the condition with the highest evaluation. This special rule overrides the general principle that veterans can receive multiple ratings for distinct disabilities, and it applies regardless of whether the conditions have different symptoms or treatments . The key exception is when a condition is not truly respiratory in nature, such as central sleep apnea (a neurological condition), which may not be subject to this rule .

The Special Rule for Respiratory Conditions

What 38 C.F.R. § 4.96 Says

The regulation states: "Ratings under diagnostic codes 6600 through 6817 and 6822 through 6847 of § 4.97 will not be combined with each other. A single rating will be assigned under the diagnostic code which reflects the predominant disability with elevation to the next higher evaluation where the severity of the overall disability warrants such elevation" .

This means the VA does not combine respiratory disability ratings like other conditions. Instead, it chooses the highest-rated respiratory condition and uses that as the basis for a single rating, potentially elevating it if overall respiratory severity warrants.

Diagnostic Codes Covered by § 4.96(a) :

• 6600 – Chronic bronchitis
• 6602 – Bronchial asthma
• 6603 – Pulmonary emphysema
• 6604 – Chronic obstructive pulmonary disease (COPD)
• 6847 – Sleep apnea

Why This Rule Exists

The rule is designed to prevent pyramiding compensating a veteran twice for the same manifestations . Respiratory symptoms often overlap:

By assigning a single rating, the VA ensures veterans are not compensated multiple times for the same functional impairments.

When VA Violates the Pyramiding Rule

VA is required to follow § 4.96, but errors happen. Here are common pitfalls to watch for.

Failing to Identify the Predominant Disability

The Board must explain which respiratory condition is predominant and why . In a 2025 Board decision, the Board combined asthma (30%) and sleep apnea (50%) and assigned the 50% rating because sleep apnea was the predominant disability .

If the VA fails to identify and justify the predominant condition, the decision may be flawed.

Combining Non-Respiratory Conditions

Central sleep apnea is not a respiratory condition it is a neurological disorder affecting the brain's breathing control . Under Wilson v. Shulkin, central sleep apnea can be separately rated without running afoul of § 4.96 .

The VA's pyramiding rule only applies when all conditions are respiratory in nature. If your sleep apnea is central (not obstructive), argue it should be rated under a neurological diagnostic code, separate from your respiratory rating.

Applying § 4.96 to Conditions Outside Its Scope

The diagnostic codes listed in § 4.96(a) are specific. Conditions like allergies, sinusitis (DC 6510-6514), and rhinitis (DC 6522) may be separately ratable from asthma, as they fall outside the rule's coverage .

The 20-Year Protection Exception

A 2025 Board decision illustrates the power of VA's 20-year rule. The VA found a Clear and Unmistakable Error (CUE) in a 2008 rating decision that had granted separate 50% and 30% ratings for sleep apnea and asthma. Under 38 C.F.R. § 3.951(b), a disability that has been continuously rated at or above any rating for 20 years cannot be reduced except upon a showing of fraud . The veteran's separate ratings had not reached 20 years, so the VA combined them .

When You CAN Get Separate Respiratory Ratings

There are limited exceptions to the pyramiding rule.

Sleep Apnea (Central) vs. Respiratory Conditions

If your sleep apnea is central, it is neurological, not respiratory . The VA's rule against combining respiratory ratings under § 4.96 does not apply .

Multiple Upper Respiratory Conditions

Conditions rated under different diagnostic code ranges may be separately ratable. For example, allergic rhinitis (DC 6522) and sinusitis (DC 6510-6514) fall outside the § 4.96(a) restriction .

Different Body Systems

The anti-pyramiding rule is body-system-specific. Respiratory conditions can be combined with non-respiratory conditions using standard VA math. For example, a veteran can receive separate ratings for COPD (respiratory) and hypertension (cardiovascular).

Realistic Scenario: Combining Asthma and Sleep Apnea

Veteran: U.S. Air Force, OEF Veteran. Current Ratings: 30% for asthma, 50% for obstructive sleep apnea. VA Action: The VA identifies a CUE in the original rating decision because separate ratings for asthma and sleep apnea are prohibited under § 4.96(a). The VA combines the two ratings, assigning a single 50% rating (sleep apnea is the predominant disability). Because the combined respiratory impairment does not warrant elevation to 100%, the veteran's combined rating is reduced by 30 percentage points . Outcome: Despite having distinct symptoms and different treatments (as confirmed by the veteran's physician), the VA is legally required to combine the ratings . The veteran receives a single rating for both conditions.

How the VA Assigns the Single Rating

When coexisting respiratory conditions exist under § 4.96(a), the VA:

1. Identifies the predominant disability (the condition with the highest individual rating)
2. Assigns the rating for that predominant condition
3. Considers elevation to the next higher evaluation if the overall respiratory severity warrants it

The VA considers "overall symptoms" when deciding elevation . In the 2025 case, the Board noted that the symptoms of asthma that did not overlap with sleep apnea did not establish the criteria for a 100% rating for sleep apnea (chronic respiratory failure, carbon dioxide retention, cor pulmonale, or need for a tracheostomy) .

Actionable Steps for Respiratory Claims

1. Know Which Conditions Are Covered

Familiarize yourself with the diagnostic codes listed in § 4.96(a) . If your conditions fall within the codes listed, separate ratings are barred.

2. Get Correct Diagnoses

If you have central sleep apnea, ensure your medical records correctly identify it as central, not obstructive . This distinction can be the key to a separate rating.

3. Focus on the Predominant Condition

If separate ratings are not allowed, focus on:

• Ensuring the VA correctly identifies the predominant disability
• Documenting overall severity to support elevation to the next higher rating

4. Look for Conditions Outside § 4.96

If you have conditions like rhinitis or sinusitis, these may be separately ratable from asthma .

5. Check for the 20-Year Rule

If you have had separate ratings for 20 years or more, they may be protected under 38 C.F.R. § 3.951(b) and cannot be reduced except for fraud .

6. Consider an Appeal

If the VA misapplied § 4.96 such as combining central sleep apnea with respiratory conditions, you may have grounds for a Supplemental Claim or Higher-Level Review .

Frequently Asked Questions About Respiratory Pyramiding

Can I get separate ratings for asthma and sleep apnea?

No. Under 38 C.F.R. § 4.96(a), asthma and sleep apnea are both rated under the respiratory system and cannot receive separate ratings .

What if my doctor says asthma and sleep apnea are distinct conditions?

The VA's rule applies regardless of medical opinion. Even if a physician states the conditions are distinct, VA regulations require a single combined rating .

Can I get separate ratings for COPD and sleep apnea?

No. Both COPD (DC 6604) and sleep apnea (DC 6847) fall under 38 C.F.R. § 4.96(a) .

What about central sleep apnea?

Central sleep apnea is a neurological condition and may not be subject to 38 C.F.R. § 4.96(a) .

Can I get separate ratings for rhinitis and asthma?

Possibly. Rhinitis (DC 6522) falls outside the diagnostic code range of § 4.96(a) .

What does the "predominant disability" mean?

The VA identifies the respiratory condition with the highest individual rating and uses that as the base for the single combined rating .

What is the 20-year rule for respiratory ratings?

Under 38 C.F.R. § 3.951(b), if a rating has been continuously in effect for 20 years, it cannot be reduced except upon a showing of fraud. This can protect combined ratings that have been in place for decades .
