The NAPCRG process classification for primary care.

An ad hoc committee of the North American Primary Care Research Group (NAPCRG) was appointed to develop a classification system for procedures in primary care. The committee developed and field tested a completely hierarchical four digit process code for primary care. It is hoped that with wide-spread use and further testing, the code will become a nucleus for an international companion volume to ICHPPC-2 (International Classification of Health Problems in Primary care, second edition). This first version is being made available to interested potential users at this time.
