Accident and Emergency Investigation Tables
- A broad classification of types of investigation which may be requested to assist with diagnosis as a result of Accident and Emergency Attendance.
- Certain items are sub-analysed to specify the diagnosis, investigation or treatment more precisely. These are marked with an asterisk. The diagnosis sub-analysis list follows the main diagnosis list, and the treatment sub-analysis list follows the main treatment list.
- It is recommended that computerised systems provide a minimum of six character fields for each category in order to accommodate more detailed information if necessary. Where fewer than six characters are required for coding, such as for investigations and treatments, it is recommended that the codes are left-justified and the unused fields left blank.
- ACCIDENT AND EMERGENCY INVESTIGATION is a six character code, comprising:
