About 07WT40Z

07WT40Z is the ICD-10-PCS code for a revision procedure on the bone marrow using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other operations on bone marrow, the ICD-9-CM procedure title it maps to (41.98).

For a different body part, codes include 07WK40Z (thoracic duct), 07WL40Z (cisterna chyli), 07WM40Z (thymus), 07WN40Z (lymphatic) and 07WP40Z (spleen).

The same procedure with a different approach is coded 07WT00Z (open), 07WT30Z (percutaneous) and 07WTX0Z (external).

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.
