A computing device-based system and method are described for generating a medical procedure description recorded into the system by a physician. The system and method manipulate a set of database records comprising medical content which is naturally descriptive of clinical procedures and clinically accurate diagrams which are naturally descriptive to document a medical procedure. To support the generation of a set of said medical procedure descriptions, the system and method provide interchangeable, connected, ontologically-based medical procedure database cartridges of medical content terms, rules, and diagrams that naturally describe constrained procedure representations for clinical procedure descriptions.
