About 07970ZZ
07970ZZ is the ICD-10-PCS code for a drainage procedure on the lymphatic, thorax using an open 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 incision of lymphatic structures, the ICD-9-CM procedure title it maps to (40.0).
For a different body part, codes include 07900ZZ (lymphatic, head), 07910ZZ (lymphatic, right neck), 07920ZZ (lymphatic, left neck), 07930ZZ (lymphatic, right upper extremity), 07940ZZ (lymphatic, left upper extremity), 07950ZZ (lymphatic, right axillary) and 15 more.
The same procedure with a different approach is coded 07973ZZ (percutaneous), 07974ZZ (percutaneous endoscopic) and 07978ZZ (via natural or artificial opening endoscopic).
With a different device, use 079700Z (drainage device).
It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 802 (Other O.R. Procedures of the Blood and Blood Forming Organs with MCC), DRG 803 (Other O.R. Procedures of the Blood and Blood Forming Organs with CC) and DRG 804 (Other O.R. Procedures of the Blood and Blood Forming Organs without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R.
