When Social Security issues a denial in a case, they will cite the reason(s) for the denial. Most often cases are denied because Social Security did not receive a response from some medical provider(s) or they believe the impairments are not sufficiently severe to prevent an individual from performing some type of work. Most cases should be appealed when they are denied, at least to the hearing stage so that the case can be presented to a live judge who will make a decision independent of the prior decisions. It is advisable to consult with and to obtain attorney representation to increase your chances of a favorable outcome. - Mark Davis
