ICD-10-PCS Code For Pulmonary Artery Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02LQ includes procedures performed to occlude vessels in the pulmonary artery, right. These ICD-10-PCS codes are used for inpatient documentation when a clinician completely closes the lumen or orifice of the right pulmonary artery to stop blood flow for therapeutic purposes. Accurate coding within the ICD-10-PCS 02LQ group is essential for proper inpatient reimbursement, as it captures the specific occlusion procedure performed and supports clinical documentation accuracy.

Pulmonary Artery, Right Occlusion Procedure Overview

This procedure group includes inpatient occlusion procedures performed on the right pulmonary artery, part of the heart and great vessels. These procedures involve completely closing the lumen or orifice of the right pulmonary artery to stop blood flow for therapeutic reasons. Accurate ICD-10-PCS coding of these occlusion procedures ensures the clinical action on the heart and great vessels is recorded and supports correct inpatient reimbursement and case mix assignment.

Typical Clinical Scenarios

An adult patient presents to the emergency department with massive hemoptysis and hemodynamic instability after lung biopsy; imaging confirms focal bleeding from the right pulmonary artery branch supplying the affected lobe. Inpatient care is required for urgent control of hemorrhage, and a procedure is performed to completely occlude the right pulmonary artery flow to the bleeding segment to stabilize the patient. Typical codes: 02LQ3DZ, 02LQ3ZZ
A middle-aged patient with chronic thromboembolic pulmonary hypertension undergoes a planned, elective endovascular intervention because of nonreconstructable distal occlusion of the right pulmonary artery causing refractory symptoms despite medical therapy. During the inpatient elective admission, a percutaneous endovascular occlusion with placement of an intraluminal device is performed to redirect flow and manage complications from the chronic thrombus. Typical codes: 02LQ3DZ, 02LQ4DZ
A postoperative patient develops a persistent right-sided pulmonary artery fistula after prior thoracic surgery, with ongoing right-sided hemothorax and risk of continued bleeding; operative management is undertaken to definitively close the lumen of the right pulmonary artery at the injured site. Inpatient open surgery is performed to completely occlude the right pulmonary artery lumen using an extraluminal device or direct ligation. Typical codes: 02LQ0CZ, 02LQ0ZZ
