When you receive a denial letter from Social Security, the most important thing to do is to appeal that denial within 60 days.
There are many reasons why an initial claim gets denied, and many denials have nothing to do with the merit of your disability claim. Further, the explanation provided in the denial letter is often wrong. And sometimes there is no logical reason for a denied claim.
By appealing, you will ultimately have a hearing with a U.S. Administrative Law Judge (ALJ). The hearing level can be your best chance to have your claim for disability benefits granted.
A common mistake made by claimants is that, instead of appealing a denied claim, they reapply later. Then they are denied again. Do not make that mistake! Improve your chances of receiving benefits by appealing your denied claim, rather than reapplying for benefits later.
