Based on Society of Obstetric Medicine of Australia and New Zealand (SOMANZ) Guideline for the Management of Hypertensive Disorders of Pregnancy (Lowe et al. 2014), normal pregnancy is characterised by a fall in blood pressure, detectable in the first trimester and usually reaching a nadir in the second trimester. Blood pressure rises towards pre-conception levels by term.

Hypertension in pregnancy is defined as:

1. Systolic blood pressure greater than or equal to 140 mmHg and/or

2. Diastolic blood pressure greater than or equal to 90 mmHg.

Measurements should be confirmed by repeated readings over several hours.

The diagnosis is preferably derived from and substantiated by clinical documentation which should be reviewed at the time of delivery. However this information may not be available in which case the patient may self-report to the clinician that they have been diagnosed with a hypertensive disorder.

Jurisdictions that record perinatal data using the ICD-10-AM should apply the following codes: O10.0–O10.9, O11, O13, O14.0–O14.9, O15.0 and O16.
