First, to be eligible for SSDI, a claimant must have worked (or served) 5 of the past 10 years at a job that paid into Social Security.
Veterans over the age of 55 have an advantage when filing a disability claim. In order to determine your eligibility for disability benefits, Social Security uses “GRID” rules. This qualifying system is broken down according to levels of exertion which may be performed in a work environment (sedentary, light, medium, heavy, and very heavy). Amongst these levels are three further categories that contribute to the disability determination: Age, Education, and Previous Work Experience.
