For certain exposures and eras of service, the VA presumes a condition is connected to service — meaning you may not need a nexus letter to prove the link at all. The PACT Act dramatically expanded these presumptions for burn pits and airborne hazards, and long-standing rules already cover Agent Orange, Gulf War Illness, and the contaminated water at Camp Lejeune. Knowing whether your condition is presumptive can change your entire strategy, and can reopen a claim that was denied before the law changed. These guides map out what qualifies.
