This publication describes how people live with their health condition. It is a classification of health-related domains that describe body functions and structures, activities and participation. The domains are classified from body, individual and societal perspectives. Since an individual's functioning and disability occurs in a context, "ICF" also includes a list of environmental factors. This version contains main 2 level codes (99 per list maximum), and is available in English only. The "ICF" should be useful to understand and measure health outcomes. It can be used in clinical settings, health services or surveys at the individual or population level. It is intended to complement "ICD-10 - The International Classification of Diseases and Related Health Problems" and therefore is looking beyond mortality and disease.
