The International Classification for Primary Healthcare (ICPC2) represents the most frequently used tool for the buttoning up the primary health care and family medicine clinical information. The International Classifications Committee (WICC) of the World Organization of Family Doctors (WONCA) developed the ICPC in 1987. Using the classification gives the healthcare providers means for classification the three main elements. Those are the reason for the encounter (RFE), a diagnosis or a problem and a medical care process. The existing connections between the elements can categorized the encounter prior to its completion. In the ICPC, all chapters are arranged only according to the body's systems in a way that localization has advantages compared to the etiology. Each chapter of the classification is specific enough for determination of each of the three components; their symmetrical structure and frequency allow use of each chapter, even for easy processing of the filled manually records.
