ICD-10-PCS Code For Ventricle Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 027K includes procedures performed to dilate structures in the right ventricle. These ICD-10-PCS codes are used for inpatient documentation when clinicians perform dilation of the right ventricular lumen to improve blood flow or relieve obstruction. Accurate coding within the ICD-10-PCS 027K group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Ventricle, Right Dilation Procedure Overview

Procedures in this group involve dilation of the right ventricle within the Heart and Great Vessels body system to expand an orifice or lumen. These inpatient procedures are performed to increase flow or relieve obstruction within the right ventricle. Accurate ICD-10-PCS coding for these dilation procedures ensures correct clinical documentation and supports appropriate inpatient reimbursement.

Typical Clinical Scenarios

An adult patient presents to the emergency department with sudden hemodynamic instability and signs of right ventricular outflow obstruction after blunt chest trauma. Imaging and hemodynamic monitoring identify acute narrowing of the right ventricular lumen requiring immediate surgical dilation via open approach to restore right-sided cardiac output. An open dilation is performed to relieve the obstruction and stabilize the patient. Typical codes: 027K0ZZ
A middle-aged patient with known congenital right ventricular stenosis is admitted electively for planned catheter-based intervention to increase right ventricular lumen diameter and improve symptomatic exercise intolerance. Percutaneous dilation is performed using balloon dilation with placement of a non–drug-eluting intraluminal device to scaffold the right ventricular lumen. The procedure is done in a controlled inpatient setting for definitive management. Typical codes: 027K3DZ
A patient with prior percutaneous dilation and placement of a drug-eluting scaffold in the right ventricle returns with recurrent symptomatic narrowing due to in-stent restenosis. During the inpatient admission a percutaneous endoscopic dilation is performed and a drug-eluting intraluminal device is used to address the restenosis and re-expand the right ventricular lumen. Typical codes: 027K44Z
