VERY Generally, SSDI approved if a person is found to have a medical condition (or aggregate of conditions) that will render them unable to work for a year or more; unable to sustain (i.e. work regularly) gainful (i.e. about $1,130 or so gross/avg/month). Age, education, transferability of job skills also considered. Also, SSA is not looking to see if a person can perform their past work, just if they can sustain gainful employment and, if so, are there are jobs available in the economy (not even in a person’s area)…if you can sit in a chair and scan ID badges at a gym an hour away, and work somewhat regularly and make a bit over $1,100. a month, a person will likely not be found to be disabled.
If approved, the first five months from “disability onset” date (the day SSA finds a person disabled) is not paid (think of it as short-term disability period), and then paid thereafter.
A person has to show they were still “insured” as of the disability onset date (meaning worked enough to "pre-pay the long term disability/SSDI “premiums” via payroll tax). If someone has not worked regularly, or did not pay taxes, or are filing for SSDI a long time after working, they may not even be “covered” for SSDI at the time they think their disability began. If not “covered”, that’s where SSI may apply?
You don’t have to be disabled for a year before you apply - as long as a person has a disability that is expected to prevent them from working for a year or more (think of someone in a terrible car accident where they are rendered a quadriplegic - file right away). Some people may wait a bit to file, after the date they feel is their onset date, to make certain they have a good medical history that SSA can gather at the time they do file…also, if approved, SSA pays back pay up to 12 months prior to application, so if filing and approved right away, with their alleged on-set date accepted by SSA, as long as a person files about 17 months after their onset date, same amount of disability is paid to them (beware taxes on back pay). Again, this is all general.
A person can apply on line, and it takes about 5 months or more to hear (SSA obtains medical records)…if denied, can file appeal/reconsideration, within 60 days of denial, and then it takes 3 or so months for reconsideration. Maybe longer, if SSA asks for their docs to examine the person, etc. If denied at the second/appeal/reconsideration level, they can then file for a hearing (which are about 18 months to 2 years out, from hearing request) within 60 days of the second denial.
It may be helpful to have attorney rep at a hearing, and they tend to get fees of about 25% of back pay amount. So if a super strong case, and a person does not want to pay attorney fees, they could easily apply on line and, if denied at the first and second level, then retain an attorney. Note that if a person has a hearing, and it’s denied at that level, and if they apply again, the earliest the on-set date can be, moving forward on a new application, is the date of hearing (where denied).
Tough to get SSDI, a long process, a long time not working (but if disabled, the person can’t work, so apply). If a person doesn’t have a condition that will “lump them into a “listing”” of medical conditions that SSA dictates “disabled” from the start…the time from filing an initial application to a hearing can be 3 years or so! Even then, if approved, SSA may find the “on set date” just the day of hearing, or some time in between the alleged date by the person and the hearing, or the date the person claimed is their on-set date…lots of moving parts! A person should be able to check with an attorney to get some basic information.
Good luck to them, find an attorney if need be, and they may be able to file in person at their local field office, so that would be helpful. At least make certain, if filing on line, the application is thorough - note all doctors, medications, etc. and call SSA if they have questions. Hopefully maybe they would fall into one of the immediately approved “listings”.
(and if they happen to have had LTD through their employer, go that route first…the LTD carriers often times file for SSDI themselves, and collect the benefits to net against what they pay…plan dependent).
