It is not uncommon for a Social Security Disability claim to spur from a workplace accident. However, many claimants do not realize that any worker's compensation funds received can reduce the amount of disability benefits to be received. The Social Security Administration offers a publication describing these rules in detail, which can be viewed here.
If a Social Security Disability claimant receives workers' compensation benefits from federal, state, or local government, federal or state workers' compensation agencies, or from an employer's insurance company, then that benefit, in addition to a disability benefit, cannot amount to more than 80% of the average amount earned before becoming disabled. Also included in this rule are public disability payments such as state or government retirement benefits due to disability, temporary disability benefits paid by the state, or any federal, state, or local government payment for a medical condition which rendered the claimant unable to work.
