Term: Most Responsible Diagnosis

Glossary Definition

Last Updated: 2007-09-26


The one diagnosis which describes the most significant condition of a patient which causes his/her stay in hospital. In cases where multiple diagnoses may be classified as "most responsible", the diagnosis causing the greatest length of stay (LOS) is coded as "most responsible" on the hospital discharge abstract. The most responsible diagnosis may not necessarily be the same as the admitting diagnosis. Several studies have shown similarities between this diagnosis, principal diagnosis, and primary diagnosis.
