ICPC2-ICD10 Thesaurus Source Information

Web site

The International Classification of Primary Care, Second Edition (ICPC2) – International Classification of Diseases, Tenth Revision (ICD10) Thesaurus was developed at the Academic Medical Center at the University of Amsterdam and is now maintained by the Transition Project Foundation.

ICPC2-ICD10 Thesaurus is used to code data about patients’ diagnoses.

ICPC2-ICD10 Thesaurus maps the diagnoses found in ICPC-2, which only includes the more common diagnoses, to the wide range of diagnoses found in ICD-10. This provides finer granularity for patient diagnosis in the domain of family medicine.

ICPC2-ICD10 Thesaurus also includes mappings between ICD-9-CM and ICD-10 provided by the World Health Organization (WHO).

ICPC2-ICD10 Thesaurus is used by general/family practice and primary care physicians.
