icd 9 hypertension

Hypertension, a prevalent cardiovascular condition, is typically identified by persistently high blood pressure. Under the ICD-9 classification system, it is categorized with codes ranging from 401 to 405. While hypertension may not present overt symptoms, unmanaged high blood pressure over time can significantly raise the risk of heart disease, kidney disease, and stroke.

The classification of hypertension can be approached based on severity, from mild to severe, and frequency, from common to rare. Mild hypertension is generally defined by a systolic pressure between 140 and 159 mmHg and a diastolic pressure between 90 and 99 mmHg. Patients at this stage might not require immediate pharmacological intervention but can manage their blood pressure through lifestyle modifications such as increasing exercise, improving dietary habits, and reducing weight.

Moderate hypertension is characterized by a systolic pressure between 160 and 179 mmHg and a diastolic pressure between 100 and 109 mmHg. Here, alongside maintaining a healthy lifestyle, physicians may recommend initiating drug therapy. Severe hypertension, indicated by a systolic pressure over 180 mmHg and a diastolic pressure over 110 mmHg, often necessitates urgent medical attention and may involve the concurrent use of multiple antihypertensive medications.

For individuals with hypertension, regular blood pressure monitoring is crucial. Additionally, adhering to medical advice, sustaining a healthy lifestyle, and taking medications punctually are pivotal in managing hypertension. Should blood pressure persistently rise or if symptoms like headaches and blurred vision emerge, immediate medical consultation is advised. Throughout treatment, patients should refrain from independently adjusting medication dosages or discontinuing medication to prevent blood pressure fluctuations.
