• Description:
  This report describes how the changes in the classification system used to code diagnoses reported in the National Hospital Discharge and the National Ambulatory Medical Care Surveys for utilization occurring in 1979 and later affect the comparability with similar data collected for utilization from 1968 through 1978. Comparability ratios are developed by coding the data using both coding classification revisions and dividing the national estimate based on one revision by the estimate based on the other revision. The comparability ratios can be used to estimate what the values published using one revision of the classification system would have been had coding been conducted according to the other revision.
