Common Pitfalls

⚠Not knowing that ALS is presumptive for ALL veterans with 90+ days of active service — no nexus letter needed.
⚠Not filing as soon as possible after diagnosis — the effective date is the date the claim is filed or the date of diagnosis, whichever is later.
⚠Not applying for Special Monthly Compensation (SMC) for aid and attendance or housebound benefits as the disease progresses.
⚠Not filing for Dependency and Indemnity Compensation (DIC) benefits for survivors — ALS is a service-connected cause of death for presumptive cases.
