About 079L8ZZ
079L8ZZ is the ICD-10-PCS code for a drainage procedure on the cisterna chyli using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).
For a different body part, codes include 07908ZZ (lymphatic, head), 07918ZZ (lymphatic, right neck), 07928ZZ (lymphatic, left neck), 07938ZZ (lymphatic, right upper extremity), 07948ZZ (lymphatic, left upper extremity), 07958ZZ (lymphatic, right axillary) and 12 more.
The same procedure with a different approach is coded 079L0ZZ (open), 079L3ZZ (percutaneous) and 079L4ZZ (percutaneous endoscopic).
With a different device, use 079L80Z (drainage device).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
