===READ version 1 (4-Byte READ)===

The first version was developed in the early 1980s by Dr James Read, a Loughborough general medical practitioner.<ref name="BCS">{{cite web |authorvauthors=Bentley T, Price C, Brown P |title=Structural and lexical features of successive versions of the Read Codes |url=http://www.phcsg.org/main/pastconf/camb96/readcode.htm |work=The Proceedings of the 1996 Annual Conference of The Primary Health Care Specialist Group of the [[British Computer Society]] |date=13–15 September 1996 |accessdate=2010-04-17}}</ref> The scheme was structured similarly to [[International Statistical Classification of Diseases and Related Health Problems|ICD-9]]:

* each code comprised four consecutive characters: first character 0-9, A-Z (excepting I and O), remaining three characters 0-9, A-Z/a-z (excepting i,I,o and O) plus up to three trailing period '.' characters

* the relative position of one code to another was represented through the code itself: [J...] is the common ancestor of all other codes with 'J' as the first character, and [J1..] in turn the common ancestor of all codes beginning 'J1'.
