About 07JM3ZZ

07JM3ZZ is the ICD-10-PCS code for a inspection procedure on the thymus using a percutaneous approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other nonoperative measurements and examinations, the ICD-9-CM procedure title it maps to (89.39).

For a different body part, codes include 07JK3ZZ (thoracic duct), 07JL3ZZ (cisterna chyli), 07JN3ZZ (lymphatic), 07JP3ZZ (spleen) and 07JT3ZZ (bone marrow).

The same procedure with a different approach is coded 07JM0ZZ (open) and 07JM4ZZ (percutaneous endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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