Secondary Conditions Discovery

You're rated — what else are you owed?

Free. Secondary claims don't need a new nexus to service — only a nexus to a condition you're already rated for. List what you're service-connected for and we'll surface the secondary conditions vets most commonly miss: sleep apnea secondary to PTSD, IBS secondary to PTSD, migraines secondary to TBI, radiculopathy secondary to lumbar spine, and dozens more.

Your currently service-connected conditions*Include the rating if you know it. "PTSD 70%, lumbar spine 20%, tinnitus 10%, diabetes type 2 20%"

Current combined rating (%)Current medicationsImportant — many secondaries are med side effects

Service years (optional)Lets us catch conditions that are really presumptive claims for your era — those file stronger as direct claims, not secondaries.

Deployments (optional)Locations sharpen the presumptive check — Saudi 1991, Balad 2006, Camp Lejeune 1984.

How this works

About 4 minutes.

List your current service-connected conditions
Include the rating percentage for each. Primary conditions often generate 3-5 legitimate secondaries that vets miss.
Add any new symptoms or diagnoses
Even vague mentions ("I’ve been tired all the time since the meds") help the tool connect dots.
Review the chained conditions
For each potential secondary the tool returns the causal theory, likely rating range, and what the evidence needs to show.
Draft the nexus letter
Each suggested secondary links directly to the nexus drafter with the theory pre-filled.
