VA secondary conditions explained

A secondary condition is a new condition that is caused or made worse by a condition VA has already service-connected. You do not have to prove it started in service; you have to show it is linked to your existing service-connected condition. This free mapper helps you explore which secondary conditions are commonly tied to a primary condition, what evidence supports each link, and the next steps to claim it.

Who this helps

Veterans who already have a service-connected condition and want to know what else may be connected to it. Veterans who feel their rating does not reflect everything they live with. Anyone trying to avoid leaving related conditions unclaimed.

How a primary condition can lead to a secondary one

Service-connected conditions often cause downstream problems, either directly or through the medications used to treat them. A knee injury can change your gait and lead to a hip or back condition. PTSD can contribute to sleep apnea or depression. Chronic pain can lead to mental health conditions, and many medications can cause gastrointestinal issues such as GERD. The connection is medical, so it has to be documented, not assumed.

Why medical evidence matters

A secondary claim rises or falls on the link. VA needs a current diagnosis of the secondary condition and a medical opinion connecting it to your service-connected primary condition, on a causation or aggravation theory. A nexus letter that explains the why is usually the strongest piece of evidence.

Common examples

Sleep apnea secondary to PTSD. Depression or anxiety secondary to chronic pain. Radiculopathy (nerve pain) secondary to a back condition. GERD secondary to medication for a service-connected condition. Hypertension secondary to certain conditions. These are common patterns, but your records and a medical opinion determine whether a link applies to you.
