About 07NK0ZZ
07NK0ZZ is the ICD-10-PCS code for a release procedure on the thoracic duct using an open approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to other operations on thoracic duct, the ICD-9-CM procedure title it maps to (40.69).
For a different body part, codes include 07N00ZZ (lymphatic, head), 07N10ZZ (lymphatic, right neck), 07N20ZZ (lymphatic, left neck), 07N30ZZ (lymphatic, right upper extremity), 07N40ZZ (lymphatic, left upper extremity), 07N50ZZ (lymphatic, right axillary) and 14 more.
The same procedure with a different approach is coded 07NK3ZZ (percutaneous) and 07NK4ZZ (percutaneous endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical category “Major Chest Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
