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 072K includes procedures performed to change devices in the thoracic duct. These ICD-10-PCS codes are used for inpatient documentation when an identical or similar device is removed from and replaced in the thoracic duct without cutting or puncturing the skin or a mucous membrane. Accurate coding within the ICD-10-PCS 072K group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and determines appropriate case mix and payment.

Thoracic Duct Change Procedure Overview

Procedures in this group involve changing a device in or on the thoracic duct without cutting or puncturing the skin or a mucous membrane and target the lymphatic and hemic systems. These procedures replace an identical or similar device in the thoracic duct to restore or maintain lymphatic drainage. Accurate coding ensures inpatient records reflect the specific operation performed on the thoracic duct and supports correct case mix assignment and reimbursement.

When to Use

Use a code from this group when an existing device in the thoracic duct is removed and a similar device is placed in the same thoracic duct during the same encounter without cutting or puncturing the skin or a mucous membrane. These codes are appropriate for inpatient reporting to reflect the change operation on the thoracic duct.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
072KX0Z	Change Drainage Device in Thoracic Duct, External Approach
072KXYZ	Change Other Device in Thoracic Duct, External Approach

Typical Clinical Scenarios

A hospitalized patient with a chronic thoracic duct catheter used for long-term lymphatic drainage presents with catheter malfunction and persistent high-output chylous drainage despite conservative measures. The existing external drainage device is removed and an identical external drainage catheter is placed at the same thoracic duct site without incising skin, to restore effective lymphatic drainage and control chyle loss. This is performed during the same inpatient encounter to re-establish drainage function. Typical codes: 072KX0Z
An older adult admitted from the emergency department after blunt thoracic trauma develops sudden increased chylous output from a previously placed external thoracic duct drainage catheter that has become dislodged. To manage ongoing lymphatic leak and avoid immediate open surgery, the dislodged external device is removed and a similar external drainage device is reinserted per external approach without cutting skin. The procedure is done emergently during the inpatient stay to control lymphatic loss. Typical codes: 072KX0Z
A patient with a history of thoracic duct drainage catheter placed for postoperative chylothorax returns with device site infection and failing drainage characterized by decreased output and local erythema. After appropriate management of infection, the infected external device is taken out and a new, similar external drainage device is placed at the same thoracic duct site without puncturing mucous membranes, performed during the inpatient course to restore drainage while managing the contaminated device issue. Typical codes: 072KX0Z
