icd hypertension code

Hypertension is a prevalent chronic condition diagnosed primarily based on a patient's blood pressure readings. As per the International Classification of Diseases (ICD) criteria, hypertension is coded as I10. The diagnostic thresholds for hypertension are generally defined as systolic blood pressure of 140 mmHg or higher and/or diastolic blood pressure of 90 mmHg or higher on multiple consecutive measurements without the use of antihypertensive medications.

Hypertension is categorized into different grades based on the severity: Grade 1 (mild) hypertension is indicated by systolic pressures ranging from 140 to 159 mmHg and diastolic pressures from 90 to 99 mmHg. Grade 2 (moderate) hypertension is characterized by systolic pressures between 160 and 179 mmHg and diastolic pressures between 100 and 109 mmHg. Grade 3 (severe) hypertension is identified by systolic pressures of 180 mmHg or higher and/or diastolic pressures of 110 mmHg or higher. There is also a distinct subtype known as 'isolated systolic hypertension,' which occurs in older individuals where systolic pressure is elevated while diastolic pressure remains within the normal range.

For individuals with hypertension, it is crucial to adhere to a low-sodium diet, engage in regular physical activity, maintain a healthy weight, abstain from smoking and limit alcohol consumption, and monitor blood pressure regularly. Upon diagnosis, hypertension should be managed under a physician's supervision, avoiding the use of medication without guidance. Additionally, regular follow-up appointments are essential for patients with hypertension to ensure timely adjustments to the treatment regimen.
