ICD Code I71.4

ICD code I71.4 is used to classify a medical diagnosis of an abdominal aortic aneurysm that has not ruptured. This condition involves an enlargement or bulging of the abdominal section of the aorta, which is the major blood vessel supplying blood to the body. The code indicates that the aneurysm is present but has not yet resulted in a rupture, which is a critical distinction for treatment and management purposes.

1. Presence of an Abdominal Aortic Aneurysm (AAA): The patient must have a confirmed diagnosis of an abdominal aortic aneurysm. This is typically identified through imaging studies such as an ultrasound, CT scan, or MRI, which reveal an enlargement of the abdominal aorta.

2. Absence of Rupture: The aneurysm must be intact, meaning there is no evidence of rupture. This is determined through clinical evaluation and imaging, which should show no signs of bleeding or rupture in the abdominal cavity.

3. Aneurysm Size: While not a strict criterion for using the code, the size of the aneurysm is often documented. Typically, an aneurysm is considered significant if it measures 3 cm or more in diameter.

4. Patient Symptoms: The patient may be asymptomatic or present with non-specific symptoms such as abdominal or back pain. However, the absence of acute symptoms related to rupture, such as sudden severe pain, hypotension, or shock, is crucial.

5. Risk Factors: Documentation of risk factors such as age, smoking history, hypertension, or a family history of aneurysms can support the diagnosis but is not mandatory for coding.

6. Monitoring and Management Plan: The medical record should reflect a plan for monitoring the aneurysm, which may include regular imaging follow-ups and lifestyle modifications or medical management to control risk factors.

By adhering to these criteria, healthcare providers can ensure accurate and appropriate use of the ICD code for an abdominal aortic aneurysm without rupture.

For the ICD code I71.4, which pertains to an abdominal aortic aneurysm without rupture, the relevant CPT codes that may be applicable for treatment or procedures include:

1. 35102 - Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, abdominal aorta, with or without patch graft.

2. 34800 - Endovascular repair of infrarenal abdominal aortic aneurysm or dissection; using aorto-aortic tube prosthesis.

3. 34802 - Endovascular repair of infrarenal abdominal aortic aneurysm or dissection; using modular bifurcated prosthesis (1 docking limb).

4. 34803 - Endovascular repair of infrarenal abdominal aortic aneurysm or dissection; using modular bifurcated prosthesis (2 docking limbs).

5. 34804 - Endovascular repair of infrarenal abdominal aortic aneurysm or dissection; using unibody bifurcated prosthesis.

6. 34805 - Endovascular repair of infrarenal abdominal aortic aneurysm or dissection; using aorto-uni-iliac prosthesis with ipsilateral femoral-femoral prosthetic graft.

7. 34825 - Placement of proximal or distal extension prosthesis for endovascular repair of infrarenal abdominal aortic or iliac artery aneurysm, for extension of aortic or iliac endograft deployment.

8. 75952 - Endovascular repair of infrarenal abdominal aortic aneurysm or dissection, radiological supervision and interpretation.

These CPT codes are typically used in the context of surgical or endovascular interventions for the management of an abdominal aortic aneurysm without rupture. It's important for healthcare providers to select the appropriate CPT code based on the specific procedure performed and the clinical scenario.
