Oh shit, I did ot notice the “why” part of your question.
Having done SS disab litigation for the past 17 years, I am unaware of any nefarious plot to deny deserving people. However, it is a statutorily created scheme, and people must meet certain criteria to qualify. Most significantly, having a medically diagnosable impairment that renders you unable to perform your usual job does not mean you are entitled to SS disab bens.
Also, a great deal of disab claims are driven by economics. It is not coincidental that disab claims rise with unemployment…
Moreover, many SS disab claims are the result of attempts at cost shifting: businesses and insurers wish to get folks off their private disab plans, states wish to get them off their plans. In fact, in order to receive many private and state disab bens, a claimant is required to apply for SS. And a determination by any other agency using their own standards does not mean a person will be entitled to SS.
It is a complex scheme with numerous factors, so I will not attempt any more generalizations here absent a specific query…
Broomstick is spot on with her comment about insufficient documentation. The claimant is required to prove that they are disabled. Very important are detailed doctors’ opinions - not general conclusions of disability. But detailed statements of what a person can or cannot do with cites to the medical evidence supporting that opinion.
A lawyer can be helpful in identifying the correct pigeonhole your husband will need to be classified in, and developing the record to get him there.
Attorney fees are somewhat complex, and I don’t want to go into them here and now. But my opinion is that an attorney is worthwhile, especially if you have already been denied, and very much so if you are attending a hearing. A lot depends on your personal ability to obtain medical records, and deal with a complex regulatory system. Also depends on how important the back benefits are to you, as opposed to getting monthly checks.
Good luck.
