Subsequent Injury Fund

What is the Subsequent Injury Fund (SIF)?

The Subsequent Injury Fund was created on a state-by-state basis after World War II to encourage the hiring of injured veterans by providing lifetime income benefits (LIBs) to employees with pre-existing injuries. Today, the fund continues to help encourage employers to hire employees with pre-existing conditions, by reducing the liability employers face should the employee receive a new injury while at work that would entitle them to LIBS. The SIF has also expanded to include reimbursement of over paid, unrecoupable, workers’ compensation benefits under specific circumstances prescribed by statute

Blaise Gerstenlauer serves as the SIF Administrator and is the primary contact.

How is the SIF funded?

The SIF is funded, by law, from death benefits that insurance carriers must pay on fatal workers’ compensation claims where there are no eligible beneficiaries.

Lifetime income benefits

Texas Labor section 408.162 indicates (a) If a subsequent compensable injury, with the effects of a previous injury, results in a condition for which the injured employee is entitled to lifetime income benefits, the insurance carrier is liable for the payment of benefits for the subsequent injury only to the extent that the subsequent injury would have entitled the employee to benefits had the previous injury not existed. & (b) The Subsequent Injury Fund shall compensate the employee for the remainder of the lifetime income benefits to which the employee is entitled.
