What is the Onset Date?

Kayla Moreland , May 13, 2015

The onset date is the date you became disabled. 

Sometime this date is associated with a traumatic event, for example an accident after which you became unable to work.

With chronic illness, it may be more difficult to establish a clear onset date. This determination of onset involves consideration of your allegations, work history, if any, and the medical and other evidence concerning the severity of your medical condition. The weight to be given any of the relevant evidence depends on the individual case. The day your illness caused you to stop working  is frequently of great significance in selecting the proper onset date. Choosing the correct date is very important and it can affect what kind of benefit you will be entitled to receive.
