Understanding Combined Diastolic and Systolic Secondary Hypertension

Combined diastolic and systolic secondary hypertension refers to a condition where both systolic and diastolic blood pressure readings are elevated, and this high blood pressure is caused by an identifiable underlying medical condition. In the International Classification of Diseases, 11th Revision (ICD-11), this specific diagnosis is assigned the code BA04.0. It falls under the broader category of Hypertensive diseases within Chapter 11, Diseases of the circulatory system. Unlike primary hypertension, which has no single identifiable cause, secondary hypertension stems directly from another health issue, such as kidney disease, endocrine disorders, or vascular problems.

Identifying the Origins of Secondary Hypertension

The development of combined diastolic and systolic secondary hypertension is linked to various underlying medical conditions that disrupt the body's normal blood pressure regulation. These can include:

• Kidney diseases, such as chronic kidney disease or renal artery stenosis.
• Endocrine disorders, including conditions affecting the adrenal glands (like Cushing's syndrome or hyperaldosteronism) or thyroid issues (thyrotoxicosis).
• Vascular abnormalities, such as fibromuscular dysplasia of arteries.
• Certain medications or substances.

Identifying and addressing the root cause is crucial for effective management.

Diagnosing Combined Diastolic and Systolic Secondary Hypertension

The diagnosis of combined diastolic and systolic secondary hypertension involves a comprehensive approach. It begins with accurate blood pressure measurements, typically requiring multiple readings over time to confirm elevated systolic pressure above 140 mmHg and diastolic pressure above 90 mmHg. A key aspect of diagnosing secondary hypertension is the subsequent investigation to identify the specific underlying condition responsible for the elevated blood pressure. This may involve blood tests, urine tests, imaging studies, and other diagnostic procedures tailored to investigate potential causes affecting the kidneys, endocrine system, or vasculature.

Managing Secondary Hypertension: Treatment Approaches

Effective management of combined diastolic and systolic secondary hypertension centres on addressing the identified underlying cause. Treatment strategies may include:

• Medications to treat the specific condition causing the hypertension (e.g., drugs for kidney disease, endocrine disorders).
• Lifestyle modifications, such as adopting a healthy diet, regular physical activity, maintaining a healthy weight, and reducing sodium intake.
• Antihypertensive medications may be prescribed to control blood pressure levels, often in conjunction with treating the primary condition.

A personalised treatment plan developed with a healthcare professional is essential.

Coding and Documentation for BA04.0

For accurate medical billing and record-keeping, the ICD-11 code BA04.0 is used to denote Combined diastolic and systolic secondary hypertension. When documenting this condition, healthcare providers should clearly identify and record the specific underlying cause of the hypertension. This detailed documentation is vital for comprehensive patient care and appropriate coding practices. The ICD-11 classification system provides specific codes for various secondary hypertension causes, allowing for precise reporting.

When to Seek Medical Attention for Hypertension

Individuals experiencing persistently high blood pressure readings, particularly those with both elevated systolic and diastolic numbers, should consult a healthcare professional promptly. While hypertension can sometimes be asymptomatic, symptoms such as severe headaches, dizziness, vision changes, chest pain, or shortness of breath may indicate a more serious condition and require immediate medical evaluation. Early diagnosis and management of secondary hypertension are key to preventing potential complications.
