The resolution involves the concept of proximate or primary cause of death which is
                        defined and analyzed below with guidelines for its application.
                     
                     Definition:
                     The proximate or primary cause of death is either: (1) the direct cause of death;
                        or (2) the initiating event in an unbroken chain of events, each causing the next,
                        that leads to and ultimately causes death.
                     
                     The pivotal question is: “But for this accidental injury, would the deceased have
                        died at this particular time?
                     
                     Analysis:
                     SSA must determine the cause of death in the context of the statutory requirements.
                        Use of the term “accident” on the death certificate does not compel a finding of accidental
                        death under the Act.
                     
                     Where a pre-existing disease exists, SSA must decide which factor (the accidental
                        injury or the pre-existing disease) was primarily responsible for causing death at
                        the particular time that death occurred. A preexisting disease (or illness) does not,
                        necessarily, preclude a finding that the accidental injury was the proximate cause
                        of death.
                     
                     In deciding whether the injury or the disease is the proximate cause of death, SSA
                        must determine which is the more substantial contributing factor. The injury is the
                        proximate cause of death if the medical evidence ”to a reasonable degree of certainty”
                        shows that pre-existing conditions were under control at the time of the accident,
                        even if they were active and capable of ultimately causing death. That is, the disease
                        was not the direct or concurring cause of death.
                     
                     Guidelines:
                     In conjunction with the above discussion, use the following guidelines for determining
                        the proximate cause.
                     
                     
                        -

                                 If an accident causes or initiates a disease or infirmity from which death results,
                                    consider the accident to be the sole cause of the fatality.

                                 If the worker has a disease or infirmity, which is not, in and of itself, expected
                                    to endanger life, and an accident aggravates it to fatal proportions, consider the
                                    accident to be the sole cause of the fatality.

                                 If the worker had an active, progressive disease, which, in and of itself, could have
                                    caused death more than 9 months after the date of the marriage, and an accident aggravated
                                    it so that death resulted before 9 months of marriage elapsed, consider the accident
                                    to be the sole cause of the fatality.

                                    it so that the death resulted at a particular time, do not consider the accident to
                                    be the sole cause of death.

                                    an unrelated disease or infirmity directly causing death, do not consider the accident
                                    to be the sole cause of death.

                                    their own life and therefore, placed on life support, consider the accidental injury,
                                    not the termination of the life support pursuant to a living will, to be the sole
                                    cause of death. A living will, also called an advance directive or advance medical
                                    directive, may be oral or written.
