Monthly Increase Possible

Secondary conditions are the VA’s best-kept secret for increasing your disability rating. If you have a service-connected condition that causes or aggravates another condition, you may be entitled to additional compensation. Yet most veterans leave thousands of dollars on the table by not understanding this powerful benefit.

Warning: Critical Point: You must have at least one service-connected condition before filing secondary claims. Secondary conditions cannot be your first VA disability claim.

Understanding Secondary Service Connection

Secondary service connection applies when:

Causation

Your service-connected condition directly causes a new condition

Example: PTSD causes sleep apnea due to weight gain from medications

Aggravation

Your service-connected condition worsens a pre-existing condition

Example: Back injury aggravates pre-existing depression

Key Legal Standard: You need medical evidence showing the secondary condition is “at least as likely as not” (50% or greater probability) caused OR aggravated by your service-connected condition.

Specific timeline showing progression
Uses “at least as likely as not” language
Addresses any contradictory evidence

How to File Secondary Claims

Ensure Primary is Service-Connected

Wait for your primary condition rating before filing secondary claims

Tip: Check your rating decision letter for the effective date

Get Diagnosed & Treated

Establish treatment history for secondary condition

Tip: 6 months of treatment strengthens your claim

Obtain Nexus Letter

Get medical opinion linking conditions

Tip: Specialist opinions carry more weight

File VA Form 21-526EZ

Mark as “secondary” and identify primary condition

Tip: File online for faster processing

Understanding Combined Ratings

Important: VA math is NOT simple addition. Multiple ratings are combined using the “whole person” concept.

Example: PTSD (70%) + Sleep Apnea (50%)

Start with 70% disabled = 30% “whole”
50% of remaining 30% = 15%
70% + 15% = 85%
Rounds to 90% combined rating

Monthly difference: $1,998.52 (90%) vs $1,716.28 (70%) = $282.24/month extra

Common Secondary Claim Mistakes

Filing Too Early

Waiting for primary to be granted is essential

Weak Medical Evidence

Generic letters without specific rationale

Missing Timeline

Not showing when secondary condition started

Wrong Form

Not marking claim as “secondary”

Contradictory Records

Medical records showing other causes

No Current Treatment

Claiming condition without ongoing care

Strategies for Secondary Claim Success

Dr. Lee’s Secondary Claim Playbook:

1. Document the Progression

Keep a timeline showing how your primary condition led to the secondary. Include specific examples of cause and effect.

2. Get Specialist Opinions

A psychiatrist’s opinion on mental health secondaries carries more weight than a general practitioner.

3. File Strategically

Consider filing multiple secondaries together if they’re all related to the same primary condition.

4. Use Medical Literature

Include studies showing the connection between your conditions. This strengthens medical opinions.
