Caring for Survivors Act of 2023 This bill increases the monthly rate of dependency and indemnity compensation payable to surviving spouses through the Department of Veterans Affairs (VA). Dependency and indemnity compensation is a monthly payment made to eligible survivors (i.e., spouses, parents, or children) of (1) certain veterans who died as a result of a service-connected condition; (2) service members killed while on active military duty or active or inactive duty for training; or (3) veterans who did not die from a service-connected condition, but were totally disabled by a service-connected disability for a certain period of time. The bill also (1) reduces, from 10 years to 5 years, the period of time that certain veterans must have been rated totally disabled due to a service-connected disability in order for a survivor to qualify for benefits; and (2) specifies the amount that is payable to survivors of veterans who were rated totally disabled for a period of less than 10 years before their death.
