ICD-10-PCS Code For Thoracic Duct: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 07WK includes procedures performed to revise portions of the thoracic duct in the lymphatic and hemic systems. These ICD-10-PCS codes are used for inpatient documentation when a portion of the thoracic duct requires correction, repositioning, or revision due to malfunction, displacement, or complication. Accurate coding within the ICD-10-PCS 07WK group is essential for proper inpatient reimbursement, as it captures the specific revision procedure performed and supports clinical documentation accuracy.

Thoracic Duct Revision Procedure Overview

Procedures in this ICD-10-PCS group involve revision of the thoracic duct and target the lymphatic and hemic systems. These operations correct, reposition, or revise a portion of a malfunctioning device or the position of a displaced device related to the thoracic duct. Accurate coding captures the specific revision performed on the thoracic duct and is important for appropriate inpatient case classification and reimbursement.

Typical Clinical Scenarios

An adult patient is admitted emergently after blunt thoracic trauma with persistent high-output chylothorax despite chest tube drainage. Imaging suggests disruption of the thoracic duct with an externalized drainage catheter that is malpositioned and not controlling the leak; the surgical team performs an open revision to reposition and secure the drainage device and repair the duct as feasible. A revision procedure from this group is performed to correct the malfunctioning drainage device and reestablish thoracic duct continuity and lymphatic drainage. Typical codes: 07WK00Z
A patient with a history of prior thoracic duct stent placement for refractory chylous ascites is scheduled for an inpatient, elective percutaneous procedure because surveillance imaging shows stent migration with occlusion of lymphatic flow. The interventional team performs a percutaneous revision of the intraluminal device to reposition the stent and restore patency of the thoracic duct. The procedure targets the displaced intraluminal device and uses a percutaneous approach to correct its position. Typical codes: 07WK3DZ
A postoperative patient develops recurrent chylothorax after recent thoracic duct reconstruction with an implanted infusion device; conservative measures fail and the device is found to be malfunctioning. The team performs a percutaneous endoscopic revision to exchange or repair the implanted infusion device affecting the thoracic duct and address the ongoing lymphatic leak. The intervention revises the device to correct its function and reduce lymphatic leakage. Typical codes: 07WK43Z
