What is a Secondary VA Disability Claim?
A secondary condition is a disability that was caused or aggravated by a service-connected condition. Under 38 CFR § 3.310, the VA will grant service connection for a secondary condition if you can show a medical relationship (nexus) between your already service-connected condition and the new condition.
In this case, you would claim that your service-connected Crohn's Disease caused or worsened your Chronic Kidney Stones.
Secondary claims are one of the most effective ways to increase your combined VA disability rating and monthly compensation.

Evidence Needed for This Secondary Claim
1. Nexus Letter (Most Important)
Get a medical opinion letter from a doctor stating that your Chronic Kidney Stonesis "at least as likely as not" caused by or aggravated by your service-connected Crohn's Disease. This is the most critical piece of evidence for a secondary claim.
2. Current Diagnosis
Medical records showing a current diagnosis of Chronic Kidney Stones. VA treatment records, private medical records, or a current exam will work.

You must already have Crohn's Disease rated as service-connected. If not, file for that first or file both claims simultaneously.
4. Personal Statement
A detailed statement (VA Form 21-4138) describing how your Crohn's Disease symptoms led to or worsened your Chronic Kidney Stones. Include specific examples of how both conditions affect your daily life.
