The International Classification of Functioning, Disability and Health (ICF) does not yet classify personal contextual factors. To determine the interaction of these factors on activities and participation of a person as well as their influence on the probable outcome of interventions, they must be taken into account in individual sociomedical expertises. Therefore, a group of medical experts working for the social health insurance medical advisory boards in Germany compiled a proposal for a systematic classification of personal contextual factors into domains, categories and items with respect to the ethical guidelines of the ICF. In a second step the main issues were transferred into the preliminary draft for a short version which will be published later to give support for practical daily use in health insurance matters.
