About 0RSTX5Z

0RSTX5Z is the ICD-10-PCS code for a reposition procedure on the left carpometacarpal joint using an external approach with external fixation device. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to closed reduction of dislocation of hand and finger, the ICD-9-CM procedure title it maps to (79.74).

For a different body part, codes include 0RSLX5Z (right elbow joint), 0RSMX5Z (left elbow joint), 0RSNX5Z (right wrist joint), 0RSPX5Z (left wrist joint), 0RSQX5Z (right carpal joint), 0RSRX5Z (left carpal joint) and 5 more.

The same procedure with a different approach is coded 0RST05Z (open), 0RST35Z (percutaneous) and 0RST45Z (percutaneous endoscopic).

With a different device, use 0RSTX4Z (internal fixation device) and 0RSTXZZ (no device).

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.
