The International Classification of Primary Care (ICPC) is a classification method for primary care encounters. The ICPC-3 strives to be a person centered classification for Primary Care, building on the foundations of the ICPC-2. It includes references to existing international standards such as ICD-10, ICD-11, ICF as well as SNOMED CT clinical terminology. It provides a framework for documenting and organizing clinical data from primary care patient contacts.

The ICPC-3 includes codes for the four key elements of healthcare encounters:

the reason for the encounter (RFE);
the diagnosis and/or health problem;
functioning (i.e. information about activities/participation, physiological functions and about personal and environmental factors related to the health problem);
processes of care.

History

The ICPC was developed by the WONCA International Classification Committee (WICC), and was first published in 1987 by Oxford University Press (OUP). A revision and inclusion of criteria and definitions was published in 1998. The second revision was accepted within the World Health Organization's (WHO) Family of International Classifications.^[1] The third revision, ICPC-3, has been adopted by WONCA in December 2020 and endorsed on April 16, 2021 during the WONCA Executive meeting.^[2]

The classification was developed in a context of increasing demand for quality information on primary care as part of growing worldwide attention to global primary health care objectives, including the WHO's target of "health for all".^[3]

The first version of ICPC, which was published in 1987, is referred to as ICPC-1. A subsequent revision which was published in the 1993 publication The International Classification of Primary Care in the European Community: With a Multi-Language Layer is known as ICPC-E.

The 1998 publication, of version 2, is referred to as ICPC-2. The acronym ICPC-2-E, refers to a revised electronic version, which was released in 2000.

The ICPC-3 Project^[4] started January 2018 and published the ICPC-3 in 2020. ICPC-3 supports coding of reason(s) for encounter, symptoms and complaints, diagnoses, health problems, functioning, environmental factors, personal factors related to health and processes of care, all within one classification.
