Essential (primary) hypertension
ICD-10 I10 is a billable code used to indicate a diagnosis of essential (primary) hypertension.
Essential hypertension, also known as primary hypertension, is a chronic condition characterized by elevated blood pressure without an identifiable secondary cause. Clinically, it is defined as having a systolic blood pressure of 130 mmHg or higher, or a diastolic blood pressure of 80 mmHg or higher. The condition often presents asymptomatically, making routine screening essential for early detection. The cardiovascular system, particularly the heart and blood vessels, is primarily affected. Over time, untreated hypertension can lead to serious complications such as heart disease, stroke, kidney failure, and vision loss. The pathophysiology involves complex interactions between genetic, environmental, and lifestyle factors, including obesity, sedentary lifestyle, and high sodium intake. Diagnosis typically involves repeated blood pressure measurements and may include additional tests to rule out secondary causes. Management includes lifestyle modifications and pharmacotherapy, with a focus on achieving and maintaining target blood pressure levels to reduce the risk of cardiovascular events.

I10 covers essential hypertension, which is characterized by high blood pressure without a known secondary cause. It includes patients diagnosed with primary hypertension based on established blood pressure criteria.
I10 should be used when the diagnosis is specifically essential hypertension without any associated heart disease or secondary hypertension. If there are complications such as heart failure or chronic kidney disease, related codes like I11 or I12 should be considered.
Documentation should include consistent blood pressure readings, patient history, and any lifestyle factors contributing to hypertension. Treatment plans and follow-up notes are also essential to support the diagnosis.
