Also known as
Occlusion and stenosis of cerebral arteries
Covers stenosis and occlusion of precerebral arteries, including the internal carotid.
Other cerebrovascular diseases
May be used for unspecified cerebrovascular conditions related to carotid stenosis.
Cerebral infarction, unspecified
If stenosis leads to infarction without further specification, this can be used.

Missing or incorrect laterality (right, left, bilateral) for the stenosis impacts reimbursement and data accuracy. ICD-10-CM coding guidelines require specifying laterality.
Coding I65.2 (carotid stenosis) without further specifying if it is the internal carotid artery leads to lower reimbursement. Accurate documentation is crucial for proper coding (I65.21-).
Distinguishing between asymptomatic and symptomatic carotid stenosis is essential for accurate coding and risk adjustment. Documenting symptoms is key for proper code assignment.
Patient presents with signs and symptoms suggestive of internal carotid artery stenosis (ICAS). These include transient ischemic attack (TIA), amaurosis fugax, or cerebrovascular accident (CVA) symptoms such as unilateral weakness, numbness, facial droop, dysarthria, and aphasia. Risk factors for carotid artery disease, including hypertension, hyperlipidemia, diabetes mellitus, smoking history, and family history of atherosclerosis, were assessed. Physical examination revealed a carotid bruit upon auscultation. Duplex ultrasound of the carotid arteries was performed, demonstrating a significant stenosis of the internal carotid artery. The degree of stenosis was quantified as [percentage] based on established diagnostic criteria. Differential diagnoses considered included other causes of neurological deficits such as intracranial stenosis, cardiac embolism, and migraine. Based on the patient's presentation, medical history, and diagnostic imaging findings, a diagnosis of internal carotid artery stenosis was made. The patient's current medication list was reviewed and adjusted as needed to optimize management of risk factors. Treatment options including medical management with antiplatelet therapy, lifestyle modifications, and potential carotid endarterectomy or carotid artery stenting were discussed with the patient. The risks and benefits of each treatment option were explained. Follow-up care with neurology and vascular surgery was scheduled. Patient education regarding symptom recognition and the importance of medication adherence was provided. The patient verbalized understanding of the diagnosis, treatment plan, and potential complications. ICD-10 code I65.2 (Atherosclerosis of carotid artery) and CPT codes for the carotid ultrasound and subsequent consultations were documented.
