This paper is aimed to discuss interdisciplinarity from Habermas approach, which importance is due to the possibility of a wider and integrated view of different rationalities within health field. Some basic concepts from the habermasian paradigm are presented in order to explore the possibility of an interdisciplinarity project in health field. Special emphasis is given to the role of language as an articulator of the action in general and all the knowledge related to the action or performance in the world. Concepts from the Strategic-Situational Planing approach are also taken as reference to discuss and an example of the problem of an increase of AIDS incidence, from the point of view interdisciplinary from the Health Department's perspective in a medium size municipality.
