Accurate coding before using coding pocket book 51%, while after using coding books increased to 90%. The statistical test results showed that p value less than 0.05, which means that Ho (hypothesis null) refused and it can be concluded that there was statistically differences between the proportion of accurately coded illness diagnose before and after implementation of the use of coding pocket book.
