Workers’ compensation claims typically remain open as long as the individual is receiving treatment or until the injured party reaches maximum medical improvement. This milestone varies for each person, and it can take years to determine whether a disability is temporary or permanent. Additionally, there’s a fixed time limit for filing a lawsuit. The statute of limitations can be anywhere from six months to two years from the date of the injury or the date of the last payment, depending on the worker’s state of residence. A qualified attorney can explain your state’s specific rules.
