What is the ICD-10 code for carotid vascular disease?

The ICD-10 codes for carotid vascular disease include I65.21 for right carotid stenosis, I65.22 for left carotid stenosis, and I65.23 for bilateral stenosis.

How do you document carotid stenosis?

Document carotid stenosis by specifying laterality, stenosis percentage, and confirming with imaging results. Include any underlying atherosclerosis.

Code	Description	When to Use	Key Documentation
I65.21	Occlusion and stenosis of right carotid artery	Use when there is documented stenosis or occlusion of the right carotid artery.	Doppler ultrasound showing ≥50% stenosis CTA/MRA confirming narrowing
I65.22	Occlusion and stenosis of left carotid artery	Use when there is documented stenosis or occlusion of the left carotid artery.	Doppler ultrasound showing ≥50% stenosis CTA/MRA confirming narrowing
I65.23	Occlusion and stenosis of bilateral carotid arteries	Use when there is documented stenosis or occlusion of both carotid arteries.	Doppler ultrasound showing ≥50% stenosis bilaterally CTA/MRA confirming bilateral narrowing

Documentation & Coding Risks

Avoid these common issues when documenting Carotid Vascular Disease.

Vague documentation of carotid disease

Impact

Clinical: Potential misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Reduced reimbursement due to unspecified coding.

Mitigation

Educate clinicians on documentation specificity, Use templates to guide documentation

Using I77.9 for specific stenosis cases

Impact

Reimbursement: Lower reimbursement due to unspecified coding., Compliance: Non-compliance with coding specificity requirements., Data Quality: Decreased data quality and accuracy.

Mitigation

Ensure documentation specifies stenosis or occlusion to use I65.2- codes.

Documentation specificity

Impact

Lack of specific documentation for carotid stenosis can lead to audit findings.

Mitigation

Implement documentation templates and clinician education.
