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 07HK includes procedures performed to insert nonbiological appliances into the thoracic duct in the lymphatic and hemic systems. These ICD-10-PCS codes are used for inpatient documentation when a device is placed in the thoracic duct to monitor, assist, perform, or prevent a physiological function. Accurate coding within the ICD-10-PCS 07HK group is essential for proper inpatient reimbursement, as it captures the specific insertion procedure performed and supports clinical documentation accuracy.

Thoracic Duct Insertion Procedure Overview

This procedure group includes insertion procedures that place a nonbiological appliance into the thoracic duct and target the lymphatic and hemic systems. These procedures involve introducing devices that monitor, assist, perform, or prevent a physiological function without replacing the thoracic duct. Accurate ICD-10-PCS coding is important for inpatient reimbursement and for reflecting the specific insertion procedure performed on the lymphatic system.

When to Use

Use codes from this group when an inpatient procedure involves placing a device into the thoracic duct to provide monitoring, assistance, or prevention of a physiological function. Do not use these codes for removal, replacement, or other operations that are not insertion into the thoracic duct.

Typical Clinical Scenarios

Patient with chylothorax following recent blunt thoracic trauma is admitted with progressive respiratory distress and large, persistent chylous pleural effusion despite conservative management (chest tube drainage and dietary modification). Surgical teams plan placement of a device into the thoracic duct to control lymphatic leak and allow continued monitoring/adjunct infusion to promote closure of the leak during the inpatient stay. Typical codes: 07HK03Z, 07HK33Z
Elective inpatient admission for a patient with recurrent malignant chylous ascites secondary to metastatic lymphoma who requires targeted intralymphatic chemotherapy or infusion therapy directly into the thoracic duct to reduce tumor burden and control lymphatic drainage. A nonbiological infusion device is placed into the thoracic duct under image guidance to deliver therapy and manage ongoing effusions. Typical codes: 07HK03Z, 07HK43Z
Patient develops postoperative high-output chylous leak after esophagectomy with hemodynamic instability and failure of bedside measures; interventional procedure is performed emergently to insert a device (radioactive tracer or other targeted agent) into the thoracic duct to localize and assist in definitive management of the leak and to permit directed therapy. Typical codes: 07HK01Z, 07HK31Z
