About 0RWTX4Z
0RWTX4Z is the ICD-10-PCS code for a revision procedure on the left carpometacarpal joint using an external approach with internal fixation 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).
For a different body part, codes include 0RW0X4Z (occipital-cervical joint), 0RW1X4Z (cervical vertebral joint), 0RW4X4Z (cervicothoracic vertebral joint), 0RW6X4Z (thoracic vertebral joint), 0RWAX4Z (thoracolumbar vertebral joint), 0RWCX4Z (right temporomandibular joint) and 18 more.
The same procedure with a different approach is coded 0RWT04Z (open), 0RWT34Z (percutaneous) and 0RWT44Z (percutaneous endoscopic).
With a different device, use 0RWTX0Z (drainage device), 0RWTX3Z (infusion device), 0RWTX5Z (external fixation device), 0RWTX7Z (autologous tissue substitute), 0RWTX8Z (spacer), 0RWTXJZ (synthetic substitute) and 1 more.
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.
