Generally, you can still receive the Social Security Disability Insurance (SSDI)benefit based on your individual wage record if you receive other benefits, such as service-connected Veterans’ benefits or a union pension.
However, there are exceptions. For example, if you receive Workers’ Compensation benefits or a pension from a job in which you did not pay Social Security (FICA) taxes, your disability insurance benefits may be reduced or eliminated. In addition, your disability insurance benefits may reduce other benefits you receive, such as long-term disability benefits from an employer.
On the other hand, the need-based Supplemental Security Income (SSI) disability benefit can be reduced by any other benefits that you receive. However, there are often exceptions for benefits such as public aid.
