To apply for Federal Employees Retirement System, or FERS, disability retirement benefits, employees must first fully document their medical condition and apply for disability benefits from the Social Security Administration, reports the U.S. Office of Personnel Management. They then fill in form SF3107, Application for Immediate Retirement, and form SF3112, Documentation in Support of Disability Retirement. Employees submit these forms and supporting documentation along with proof of the Social Security disability application to the Office of Personnel Management.
If employees have left their federal service jobs within no more than 31 days, the agency that employed them assists in filling in the forms and sending them in, explains the U.S. Office of Personnel Management. If they have not worked for more than 31 days, they must send the forms themselves. After 31 days, their employing agency and former supervisors must complete additional forms. Former employees must submit the entire application package within one year of employment termination. After approval of their disability retirement applications, former employees may have to continue undergoing periodic medical examinations to keep receiving benefits.
To be eligible for FERS disability retirement benefits, employees must finish 18 months or more of federal civilian service, according to the U.S. Office of Personnel Management. Diseases or injuries must cause the disabilities while the employees are in federal service, and the prognosis of the time period of the disabilities must be at least one year. The agencies where the employees work must verify they are unable to perform their present job or any other job at a similar grade.
