Name of the Condition

• Aortic aneurysm of unspecified site, without rupture
• ICD-10 Code: I71.9

Summary

An aortic aneurysm without rupture refers to a dilation or bulging of the aortic wall that has not yet torn. The aorta is the largest artery in the body, and this type of aneurysm can occur anywhere along its length. Although it does not involve tearing, this condition requires careful monitoring as it can lead to serious complications if left unchecked.

Causes

Aortic aneurysms may be caused by factors that weaken the aortic wall, including:

• Chronic high blood pressure
• Atherosclerosis (buildup of plaque in the arteries)
• Genetic conditions such as Marfan syndrome or Ehlers-Danlos syndrome
• Previous injury or trauma to the chest or abdomen

Risk Factors

• Age: Risk increases with age, particularly after 65.
• Gender: More common in males.
• Smoking history
• Family history of aneurysms
• High blood pressure or cholesterol
• Connective tissue disorders

Symptoms

Most people with an unruptured aortic aneurysm have no symptoms. However, some might experience:

• A pulsating feeling near the navel
• Deep or constant pain in the abdomen or back
• A persistent cough or difficulty in breathing if the aneurysm affects the thoracic aorta

Diagnosis

Diagnosis commonly involves:

• Ultrasound or echocardiogram
• CT scan or MRI to visualize the aorta
• Physical examination for risk assessment and potential symptoms evaluation

Treatment Options

• Monitoring: Regular imaging tests to monitor the size and growth.
• Medications: Blood pressure management using antihypertensive drugs to reduce stress on the aorta.
• Surgery: Involves endovascular repair or open-abdominal surgery if the aneurysm is large or rapidly growing.

Prognosis and Follow-Up

• Regular follow-ups with imaging tests to monitor the aneurysm’s size.
• Effective management of blood pressure and changes in lifestyle can significantly improve outcomes.
• If untreated, there is a risk of rupture, leading to serious life-threatening complications.

Complications

• Sudden rupture leading to massive internal bleeding
• Blood clot formation within the aneurysm
• Compression of nearby structures causing pain or organ dysfunction

Lifestyle & Prevention

• Quit smoking
• Maintain a healthy diet and weight
• Regular physical activity
• Control blood pressure and cholesterol levels
• Regular screening if at risk

When to Seek Professional Help

Seek immediate medical attention if experiencing:

• Sudden, intense, and persistent abdominal or back pain
• A feeling of a pulsating mass in the abdomen
• Shortness of breath or difficulty in breathing

Tips for Medical Coders

• Ensure precise location coding if the site can be specified (i.e., abdominal or thoracic).
• Differentiate between ruptured (I71.0 to I71.3) and unruptured aneurysms when coding.
• Review patient records thoroughly to identify any specifications or additional complications associated with the aneurysm.
