Carotid Stenosis ICD-10-CM Codes

What ICD-10 Codes are Used for Carotid Stenosis?

Carotid Stenosis refers to the narrowing of the carotid arteries, which can lead to reduced blood flow to the brain and an increased risk of stroke. Proper ICD-10-CM codes are essential for accurate billing and documentation. Below are 6 commonly used  Carotid Stenosis ICD Codes:

I65.21 - Nontraumatic carotid artery dissection:
This code is used when a nontraumatic dissection or tear in the carotid artery causes stenosis.

I65.22 - Nontraumatic carotid artery stenosis:

This code is used when the carotid artery narrows without a traumatic cause.

I65.23 - Nontraumatic bilateral carotid artery stenosis:

Used when both carotid arteries are narrowed without a traumatic cause.

I65.29 - Other nontraumatic carotid artery stenosis:

This code covers cases of nontraumatic carotid stenosis not falling into the previously mentioned categories.

I65.8 - Other specified occlusion and stenosis of the precerebral arteries:

This is used when carotid stenosis is present but not specifically related to the carotid arteries.

I65.9 - Unspecified occlusion and stenosis of the precerebral arteries:

This code is used when the documentation does not specify the exact location or cause of the stenosis.

Which Carotid Stenosis ICD codes are Billable?

I65.21 - Yes, billable: Reimbursement is available for nontraumatic carotid artery dissection leading to stenosis when accurately coded.

I65.22 - Yes, billable: Cases of nontraumatic carotid artery stenosis are eligible for reimbursement upon accurate coding.

I65.23 - Yes, billable: Reimbursement is applicable for nontraumatic bilateral carotid artery stenosis when documented appropriately.

I65.29 - Yes, billable: Other specified nontraumatic carotid artery stenosis can be billed when supported by medical records.

I65.8 - Yes, billable: Cases of other specified occlusion and stenosis of the precerebral arteries, including carotid stenosis, are eligible for reimbursement.

I65.9 - Yes, billable: Unspecified occlusion and stenosis of the precerebral arteries, including carotid stenosis, can be billed when detailed documentation is lacking.

Clinical Information

• Carotid stenosis refers to the narrowing of the carotid arteries, which supply blood to the brain.
• The condition is often caused by atherosclerosis, plaque buildup inside the arteries.
• Carotid stenosis can reduce blood flow to the brain, increasing the risk of stroke or transient ischemic attacks (TIAs).
• Symptoms may not be noticeable until a significant blockage occurs, but signs can include transient weakness, visual disturbances, and speech difficulties.
• Diagnosis is typically made through imaging tests such as carotid ultrasound, CT angiography, or magnetic resonance angiography (MRA).
• Treatment options include lifestyle changes, medications to manage risk factors, and, in severe cases, carotid endarterectomy or stenting to remove or bypass the blockage.
• Management of carotid stenosis aims to prevent stroke and improve blood flow to the brain.
• Regular follow-up and adherence to medical recommendations are essential for optimal outcomes.
