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 02U7 includes procedures performed to supplement biological or synthetic material in the left atrium. These ICD-10-PCS codes are used for inpatient documentation when material is placed on or in the left atrium to physically reinforce or augment atrial function. Accurate coding within the ICD-10-PCS 02U7 group is essential for proper inpatient reimbursement, as it captures the specific supplemental procedure performed and supports clinical documentation accuracy.

Left Atrium Supplement Procedure Overview

Procedures in this group involve placing biological or synthetic material to reinforce or augment the function of the left atrium within the heart and great vessels body system. These supplementary implants or grafts support atrial structure or function and may be used in conjunction with other cardiac procedures. Accurate ICD-10-PCS coding ensures inpatient records reflect the supplemental intervention performed and supports appropriate case mix assignment and payment.

Typical Clinical Scenarios

An elderly patient with chronic atrial dilation from long-standing mitral regurgitation is admitted electively for combined mitral valve repair and atrial remodeling to reduce recurrent atrial fibrillation and improve atrial mechanics; during the planned open-heart operation the surgeon reinforces the thinned left atrial wall with a synthetic patch to augment atrial structure. Typical codes: 02U70JZ.
A middle-aged patient presents urgently with left atrial wall disruption and persistent bleeding after catheter-based removal of an intracardiac mass; during the same hospitalization the team performs a percutaneous endoscopic approach to place autologous tissue substitute over the defect to reinforce the atrial wall and control bleeding. Typical codes: 02U747Z.
A young patient with recurrent thrombus formation despite anticoagulation undergoes a staged percutaneous procedure to augment left atrial appendage anatomy using a nonautologous tissue substitute to reduce stasis and improve mechanical function; this elective inpatient intervention is performed percutaneously with imaging guidance. Typical codes: 02U73KZ.
