DOCLE (Doctor Command Language),^[1][2] is a non-numeric health coding and medical classification system. The DOCLE system is used^[3] in Health Communication Network's electronic medical record and patient management software package, Medical Director. Medical Director is the most widely used electronic medical record system by Australian primary health care providers.^{[citation needed]}

DOCLE has been modelled on the Linnaean biological classification system since 1995.^[4] DOCLE generates clinical codes from ubiquitous health language using an algorithm, hence it is a human readable clinical coding system.^[4]

The design principles of DOCLE, as enumerated by the author in the DOCLE website include:

• DOCLE codes being meaningful and intentional
• DOCLE codes are derived from ubiquitous health language
• DOCLE codes grew with evolving order and speciation of large scale structures in a linnean manner.
• DOCLE codes are designed to strap together and form clinical structures using joiner codes
• The author of DOCLE, Dr. Y Kuang Oon, has likened clinical codes to "neurons" and joiner codes as the "glia"
