- If it developed while on active duty, it is ratable.
- If it developed within 1 year of separation from the military, the VA will rate it, but not the DoD since it has to be present at the time of separation for the DoD to rate it.
- If it didn’t develop until more than 1 year after separation, then it is only ratable by the VA if it can be proven to have been caused by another service-connected condition or was a direct result of military experiences, like exposure to chemicals while on active duty.
That’s it. A condition that is not strictly service-connected or caused by a service-connected condition can only be considered service-connected for service members with 8 years or more on active duty if it develops within 1 year of separation.
