ICD-10-PCS Code for Cisterna Chyli: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 07HL includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent a physiological function in the cisterna chyli. These ICD-10-PCS codes are used for inpatient documentation when a device is placed into the cisterna chyli to support lymphatic function monitoring or therapy. Accurate coding within the ICD-10-PCS 07HL group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Cisterna Chyli Insertion Procedure Overview

Procedures in this group involve the insertion of nonbiological appliances into the cisterna chyli and target the lymphatic and hemic systems. These insertion procedures are performed to monitor, assist, perform, or prevent a physiological function of the lymphatic circulation. Accurate ICD-10-PCS coding ensures inpatient documentation reflects the specific insertion and supports appropriate reimbursement and case mix classification.

Typical Clinical Scenarios

An adult patient with refractory chylous ascites after extensive abdominal oncologic surgery develops progressive abdominal distension and respiratory compromise requiring inpatient management; imaging confirms a leak from the cisterna chyli and the team plans placement of a device to drain or divert lymphatic flow to control ongoing lymphatic leak and allow healing. Typical codes: 07HL03Z, 07HL33Z
A pediatric patient with congenital lymphatic malformation causing recurrent, symptomatic chylous effusions is admitted for a planned, staged intervention to place a monitoring or infusion device into the cisterna chyli to deliver sclerosing agents and monitor lymph flow during therapy. Typical codes: 07HL43Z, 07HL4YZ
A patient previously treated with percutaneous lymphatic embolization returns with persistent lymphatic fistula and signs of infection at the access site; inpatient revision includes removal of failing material and insertion of an alternative nonbiological appliance into the cisterna chyli to restore controlled lymphatic drainage. Typical codes: 07HL3YZ, 07HL0YZ
