hypertension icd 9

Hypertension, denoted as ICD-9 code 401, is a prevalent cardiovascular condition characterized by persistently high blood pressure. Despite the lack of noticeable symptoms, unmanaged hypertension over time raises the risk for heart disease, kidney disease, and stroke. Thus, it is vital for patients to comprehend the classification of hypertension and its potential consequences.

Mild hypertension, or stage 1 hypertension, is defined by a systolic blood pressure between 130 and 139 mmHg and a diastolic pressure between 80 and 89 mmHg. While this stage typically does not lead to severe health issues, lifestyle modifications such as increased physical activity and dietary improvements are necessary to manage it.

Moderate hypertension, or stage 2 hypertension, is indicated by a systolic blood pressure between 140 and 179 mmHg and a diastolic pressure between 90 and 99 mmHg. At this stage, physicians may prescribe medication alongside lifestyle changes to mitigate the risk of cardiovascular events.

Severe hypertension, also known as stage 3 or crisis hypertension, is marked by a systolic blood pressure over 180 mmHg and a diastolic pressure over 120 mmHg. This condition is considered a medical emergency, necessitating immediate medical intervention and intensive treatment to prevent serious complications.

Individuals with hypertension should focus on a low-salt diet, maintain an appropriate weight, monitor their blood pressure regularly, and adhere to their physician's guidance on medication. Should blood pressure continue to rise or if severe symptoms such as headaches or blurred vision occur, immediate medical attention is imperative. It is essential to remember that managing hypertension requires a holistic approach, including both pharmacological treatment and lifestyle adjustments, under the supervision of a qualified healthcare provider.
