About 07JN8ZZ

07JN8ZZ is the ICD-10-PCS code for a inspection procedure on the lymphatic using a via natural or artificial opening endoscopic 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).

The same procedure with a different approach is coded 07JN0ZZ (open), 07JN3ZZ (percutaneous), 07JN4ZZ (percutaneous endoscopic) and 07JNXZZ (external).

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.
