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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02B7 includes procedures performed to excise tissue in the left atrium. These ICD-10-PCS codes are used for inpatient documentation when a portion of the left atrial tissue is surgically removed without replacement.

Typical Clinical Scenarios

An elderly patient presents to the emergency department with acute-onset atrial fibrillation and large thrombus localized to the left atrial appendage despite anticoagulation. Because the thrombus poses an immediate embolic risk and cannot be managed medically, the surgical team performs an open excision of the left atrial appendage during the same admission to remove the thrombotic source and reduce stroke risk. Typical codes: 02B70ZK
A patient with long-standing atrial fibrillation and recurrent thromboembolic events is admitted electively for definitive surgical management. The planned operation is a percutaneous endoscopic excision of the left atrial appendage to eliminate a persistent nidus of thrombus after failure of or contraindication to long-term anticoagulation. Typical codes: 02B74ZK
A patient previously treated with percutaneous left atrial appendage interventions presents with persistent symptomatic left atrial tissue causing recurrent arrhythmia and ongoing thrombus formation. During the inpatient procedure the team performs a percutaneous excision of the left atrial appendage to remove residual diseased tissue after prior incomplete intervention. Typical codes: 02B73ZK
