About 07998ZX
07998ZX is the ICD-10-PCS code for a drainage procedure on the left lymphatic, internal mammary using a via natural or artificial opening endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to biopsy of lymphatic structure, the ICD-9-CM procedure title it maps to (40.11).
For a different body part, codes include 07908ZX (lymphatic, head), 07918ZX (lymphatic, right neck), 07928ZX (lymphatic, left neck), 07938ZX (lymphatic, right upper extremity), 07948ZX (lymphatic, left upper extremity), 07958ZX (lymphatic, right axillary) and 12 more.
The same procedure with a different approach is coded 07990ZX (open), 07993ZX (percutaneous) and 07994ZX (percutaneous endoscopic).
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.
