In the following extract from mortality statistics is a large entry of 320,065 deaths during the year due to "All other diseases (residual)" from the CDC. Note that it is uncoded whereas all the other causes of death are coded. What does this mean?
Note that this single entry is the 3rd leading cause of death (after heart disease and cancer) so it is important.
I know that in cancer there is something called "minimal residual disease" meaning residual cancer cells that regrow and cause a relapse, however in that case I would have expected the mortality to coded as cancer, so this category would seem to be something different, or no?
