What must occur for a person to qualify for retirement on disability?

For an individual to qualify for retirement on disability, a substantial change in condition is necessary, as it demonstrates that their ability to work has significantly diminished due to health issues. This requirement ensures that only those who have a genuine and significant impairment affecting their capacity to perform their work duties are eligible for disability retirement.

A previous claim being accepted relates to the individual’s prior history with disability, but it does not directly address the current need for a substantial change. Reaching a certain age is relevant for standard retirement eligibility rather than disability retirement. While contributing a minimum number of years can be a factor in determining benefits, the critical requirement for disability retirement specifically hinges on the notable change in the individual's health condition. Thus, the necessity for a substantial change emphasizes the importance of current health status over other criteria.
