About 07JN0ZZ
07JN0ZZ is the ICD-10-PCS code for a inspection procedure on the lymphatic 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 07JK0ZZ (thoracic duct), 07JL0ZZ (cisterna chyli), 07JM0ZZ (thymus), 07JP0ZZ (spleen) and 07JT0ZZ (bone marrow).
The same procedure with a different approach is coded 07JN3ZZ (percutaneous), 07JN4ZZ (percutaneous endoscopic), 07JN8ZZ (via natural or artificial opening endoscopic) and 07JNXZZ (external).
It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures”, “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.
