Definition 
A condition or complaint either coexisting with the principal diagnosis or arising during the episode of admitted patient care, episode of residential care  or attendance at a health care establishment.

Additional diagnoses give information on factors which result in increased length of stay, more intensive treatment or the use of greater resources. They are required for casemix analyses relating to the severity of illness and for correct classification of patients into Australian National Diagnosis Related Groups.

Collection and Usage Attributes
Guide for Use 
Additional diagnoses should be interpreted as additional conditions that affect patient care in terms of requiring any of the following:

- Therapeutic treatment
- Diagnostic procedures
- Increased nursing care and or monitoring

Record each additional diagnosis relevant to the episode of care in accordance with the ICD-10-AM Australian Coding Standards. Generally, external cause, place of occurrence and activity codes will be included in the string of additional diagnosis codes. In some data collections these codes may also be copied into specific fields.
The diagnosis can include a disease, condition, injury, poisoning, sign, symptom, abnormal finding, complaint, or other factor influencing health status.
Verification Rules

Collection Methods 
An additional diagnosis should be recorded and coded where appropriate upon separation of an episode of admitted patient care or the end of an episode of residential care. The additional diagnosis is derived from and must be substantiated by clinical documentation.
Comment 
Additional diagnoses are significant for the allocation of Australian Refined Diagnosis Related Groups. The allocation of patient to major problem or complication and co-morbidity Diagnosis Related Groups is made on the basis of the presence of certain specified additional diagnoses. Additional diagnoses should be recorded when relevant to the patient's episode of care and not restricted by the number of fields on the morbidity form or computer screen.
External cause codes, although not diagnosis of condition codes, should be sequenced together with the additional diagnosis codes so that meaning is given to the data for use in injury surveillance.
