ICD-10-PCS Code For Left Atrium: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02L7 includes procedures performed to completely close an orifice or lumen in the left atrium. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs an occlusion of the left atrium to stop blood flow through a cardiac opening. Accurate coding within the ICD-10-PCS 02L7 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Left Atrium Occlusion Procedure Overview

Procedures in this group involve completely closing an orifice or the lumen of the left atrium to stop blood flow through a defined opening. These procedures target the heart and great vessels and are coded in the inpatient setting using the International Classification of Diseases, Tenth Revision, Procedure Coding System. Accurate coding ensures the documented occlusion procedure is captured for case mix and reimbursement and supports clinical record completeness.

Typical Clinical Scenarios

An 78-year-old patient with nonvalvular atrial fibrillation and a large thromboembolic risk with contraindication to long-term anticoagulation is admitted for a planned surgical exclusion of the left atrial appendage to reduce stroke risk. The cardiothoracic surgeon performs an open approach to completely occlude the left atrial appendage using an extraluminal occlusion device placed externally around the appendage. This inpatient procedure is selected because the patient’s anatomy and comorbidities favor a definitive surgical device closure via open access. Typical codes: 02L70CK
A 68-year-old patient presents for a percutaneous catheter-based left atrial appendage closure as an elective alternative to anticoagulation due to recurrent gastrointestinal bleeding on anticoagulants. Under conscious sedation in the inpatient setting, an intraluminal occlusion device is deployed across the left atrial appendage via a transseptal percutaneous approach to completely close the appendage lumen. The less-invasive percutaneous approach is chosen to reduce procedural morbidity while achieving full occlusion. Typical codes: 02L73DK
A patient with prior percutaneous left atrial appendage occlusion returns with device-related residual leak and recurrent thromboembolic events; after evaluation, an open revision is undertaken to completely close the left atrial appendage. The surgical team performs an open approach occlusion without placement of an additional device, directly closing the appendage lumen to eliminate persistent communication. This inpatient revision targets closure of the left atrial lumen to address the complication from the initial intervention. Typical codes: 02L70ZK
