About 07JK0ZZ

07JK0ZZ is the ICD-10-PCS code for a inspection procedure on the thoracic duct using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other diagnostic procedures on lymphatic structures, the ICD-9-CM procedure title it maps to (40.19).

For a different body part, codes include 07JL0ZZ (cisterna chyli), 07JM0ZZ (thymus), 07JN0ZZ (lymphatic), 07JP0ZZ (spleen) and 07JT0ZZ (bone marrow).

The same procedure with a different approach is coded 07JK3ZZ (percutaneous) and 07JK4ZZ (percutaneous endoscopic).

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. Procedures of the Blood and Blood Forming Organs”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
