Angina:

CODE 11     Angina (excluding unstable angina): prior existing

This code is used where there are symptoms, which can be described as chest pain or pain in either or both shoulders, the back, neck or jaw, or other equivalent discomfort (such as tightness, gripping or squeezing) suggestive of cardiac ischaemia, the onset of which occured more than two weeks ago.

CODE 12     Angina (excluding unstable angina): new onset

This code is used where there are symptoms which can be described as chest pain or pain in either or both shoulders, the back, neck or jaw, or other equivalent discomfort (such as tightness, gripping or squeezing) suggestive of cardiac ischaemia; the onset of which occured two or less weeks ago.

CODE 13     Unstable angina

This code is used where a person has experienced new onset or prior existing angina (described as chest pain or pain in either or both shoulders, the back, neck or jaw, or other equivalent discomfort (such as tightness, gripping or squeezing)), which is increasing in severity, duration or frequency.

Chronic lung disease:

CODE 21     Chronic lung disease

This code is used where there is a history or symptoms suggestive of chronic lung disease.

Heart failure:

CODE 31     Heart failure

This code is used where a person has past or current symptoms of heart failure (typically breathlessness or fatigue), either at rest or during physical activity and/or signs of pulmonary or peripheral congestion suggestive of cardiac dysfunction.

Hypertension:

CODE 41     Hypertension

This code is used where there is current use of pharmacotherapy for hypertension and/or clinical evidence of high blood pressure.

CODE 51     Ischaemic: non-haemorrhagic cerebral infarction

This code is used if there is history of stroke or cerebrovascular accident (CVA) resulting from an ischaemic event where the patient suffered a loss of neurological function with residual symptoms remaining for at least 24 hours.

CODE 52     Haemorrhagic: intracerebral haemorrhage

This code is used if there is history of stroke or cerebrovascular accident (CVA) resulting from a haemorrhagic event where the patient suffered a loss of neurological function with residual symptoms remaining for at least 24 hours.

Peripheral arterial disease:

CODE 61     Peripheral artery disease

This code is used where there is history of either chronic or acute occlusion or narrowing of the arterial lumen in the aorta or extremities.

CODE 62     Aortic aneurysm

This code is used where there is a history of aneurysmal dilatation of the aorta (thoracic and or abdominal).

CODE 63     Renal artery stenosis

This code is used where there is a history of functional stenosis of one or both renal arteries.

Sleep apnoea syndrome:

CODE 71     Sleep apnoea

This code is used where there is evidence of sleep apnoea syndrome (SAS) on history.

Myocardial infarction:

CODE 81     Previous myocardial infarction

This code is used where a person has previously experienced a myocardial infarction, excluding the current event that prompted this presentation to hospital. This may be supported by clinical documentation and evidenced by ECG changes or serum cardiac biomarker changes.

Other vascular conditions:

CODE 91     Atrial fibrillation

This code is used where there is a history or symptoms suggestive of atrial fibrillation.

CODE 92     Other cardiac arrhythmias or conductive disorders

This code is used where there is a history of other cardiac arrhythmias or conductive disorders.

CODE 93     Left ventricular hypertrophy

This code is used where there is a history or symptoms suggestive of left ventricular hypertrophy.
