About 0PSN05Z

0PSN05Z is the ICD-10-PCS code for a reposition procedure on the left carpal using an open 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 application of external fixator device, carpals and metacarpals and open reduction of fracture without internal fixation, carpals and metacarpals, the ICD-9-CM procedure titles it maps to (78.14 and 79.23).

For a different body part, codes include 0PSC05Z (right humeral head), 0PSD05Z (left humeral head), 0PSF05Z (right humeral shaft), 0PSG05Z (left humeral shaft), 0PSH05Z (right radius), 0PSJ05Z (left radius) and 9 more.

The same procedure with a different approach is coded 0PSN35Z (percutaneous) and 0PSN45Z (percutaneous endoscopic).

With a different device, use 0PSN04Z (internal fixation device) and 0PSN0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 513 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures with CC/MCC), DRG 514 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures without CC/MCC), DRG 906 (Hand Procedures for Injuries), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “Hand or Wrist Procedures, Except Major Thumb or Joint Procedures”, “Hand Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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