Acute coronary syndrome related medical history code NN

Guide for use:

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

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.
