Summary & Overview
ICD-10-PCS Code For Common Carotid Arteries: Procedure Code Group Overview
The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B335 includes procedures performed to image and digitally reformat multiplanar magnetic resonance displays of the common carotid arteries in the neck. These ICD-10-PCS codes are used for inpatient documentation when multiplanar magnetic resonance imaging with computer reformatted digital display of the common carotid arteries is performed for diagnostic evaluation or preprocedural planning. Accurate coding within the ICD-10-PCS B335 group is essential for proper inpatient reimbursement, as it captures procedure performed and supports clinical documentation accuracy and appropriate case mix assignment.
| Character | ICD-10-PCS Category | Code Group Details |
|---|---|---|
| B | Section | Imaging |
| 3 | Body System | Upper Arteries |
| 3 | Operation | Magnetic Resonance Imaging (MRI) |
| 5 | Body Part | Common Carotid Arteries, Bilateral |
Common Carotid Arteries Imaging Procedure Overview
Procedures in this group involve computer reformatted digital display of multiplanar magnetic resonance images of the common carotid arteries, performed to visualize vascular anatomy and pathology within the neck. These procedures target the vascular and central nervous system-related structures supplying the head and neck. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it captures the specific imaging procedure performed and supports precise clinical documentation and case mix assignment.
Typical Clinical Scenarios
- An elderly patient with sudden onset right-sided weakness and expressive aphasia presents to the emergency department; neuroimaging shows an acute ischemic stroke with suspicion of carotid artery territory involvement, and vascular imaging is needed to evaluate bilateral common carotid arteries for stenosis or occlusion prior to endovascular or surgical intervention. A magnet-based multiplanar imaging study of the common carotid arteries bilaterally is performed to define lumen patency and plaque morphology. Typical codes:
B335YZZ,B335ZZZ - A middle-aged patient with progressive transient ischemic attacks (recurrent episodes of unilateral weakness and visual changes) is scheduled for preoperative vascular mapping as part of elective carotid endarterectomy planning; detailed bilateral carotid vessel anatomy and plaque characterization are required for operative strategy. A planned inpatient magnet-based multiplanar study of the common carotid arteries bilaterally provides high-resolution images for surgical planning. Typical codes:
B335Y0Z,B335YZZ - A postoperative patient who underwent cervical radiation for head and neck cancer presents with worsening neck pain and suspected radiation-induced vasculopathy with possible carotid restenosis; inpatient workup is initiated due to concern for symptomatic bilateral carotid disease and potential need for urgent reintervention. A comprehensive magnet-based multiplanar evaluation of the bilateral common carotid arteries is obtained to assess for post-treatment changes and complications. Typical codes:
B335YZZ,B335ZZZ
