title: [A table for converting ICD-9 to ICPC. A common platform for health insurance statistics for primary health care and hospitals, outpatient clinics and specialists' practices].
abstract: In 1992 Rikstrygdeverket decided that the analysis of billing systems and certificates of illness issued by the primary and secondary health care services should be based on ICPC. All general practitioners are expected to use ICPC-codes. Doctors working in hospitals and other specialists have already used the ICD-9 classification for many years and did not want to have to use two different encoding systems. To obtain a common platform for statistical analysis, a referral system was necessary to convert ICD-9 codes to corresponding ICPC codes. In this article, the head of project discusses the material and methods used in this project, and summarizes the results and the structure and formats of the referral table. The author also briefly discusses the potentials and limitations when diagnostic codes are converted from ICD-9 to ICPC.
