Future health care expenditures (HCE) are projected based on expected mortality and age-specific death related costs which are relatively low among the oldest old, assuming healthy ageing. This study examined the impact of age and death on individual HCE and the change of the impact over time in order to explore the influence of population ageing on future HCE. We used a nationally representative medical and pharmacy claims data of the Korean National Health Insurance from 2002 to 2013. We used two part models with the interaction term of death, age and year to explore the change in death related costs among the elderly over time. A total of 123,127 elders were included, of whom 26,387 were deceased in the study period. Younger decedents consumed higher death related costs than those who died later. HCE among the oldest old increased faster than that of the younger old. The difference in death related costs between the oldest decedents and the younger decedents decreased over time. We suggest that future HCE projections should count on (1) the changes in population structure, (2) death related costs by age group, and (3) the increasing trend of death related costs among the oldest old.
