About 07WT00Z

07WT00Z is the ICD-10-PCS code for a revision procedure on the bone marrow using an open 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 07WK00Z (thoracic duct), 07WL00Z (cisterna chyli), 07WM00Z (thymus), 07WN00Z (lymphatic) and 07WP00Z (spleen).

The same procedure with a different approach is coded 07WT30Z (percutaneous), 07WT40Z (percutaneous endoscopic) 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.
