If you have been an employee of the state of North Carolina or an employee of a NC public school system for five years or more, you are probably covered by the NC State Disability plan. The NC State Disability plan is administered by the NC Department of State Treasurer. You would be wise to carefully read the summary plan description booklet provided to those covered by the NC State Disability plan.
Those who are on benefits provided by the NC State Disability insurance should also apply for Social Security disability benefits. The benefits provided by the NC State Disability plan are reduced by Social Security disability benefits but even if you do not get on Social Security disability benefits your NC State Disability insurance benefits will eventually be reduced as if you had been approved for Social Security disability benefits. The Department of State Treasurer does not keep this a secret but they do not stress it to those receiving benefits under the NC State Disability plan like they should. People start receiving their NC State Disability plan benefits, do not bother to file a claim for Social Security disability benefits or appeal a denial of those benefits and go along happily for a time and then suddenly the NC State Disability plan benefits are dramatically reduced with no advance warning.
Do not let this happen to you! If you are on NC State Disability benefits, file a claim for Social Security disability benefits, file any appeals and hire a lawyer. The NC State Disability plan gives you a credit for any attorney fees you pay, which means, in effect, that the state pays your attorney fee.
