A conversion code from the RCGP to the ICHPPC classification system

Faculty members from four family medicine training programs participated in the production of a definitive conversion of the Royal College of General Practitioners Classification of Diseases as modified for use with problem-oriented medical records (RCGP) to the International Classification of Health Problems for Primary Care (ICHPPC). The method used to produce the conversion and the several problems encountered are described. A detailed translation with the appropriate ICHPPC equivalent for each RCGP diagnostic title and code number is provided.
