About 0PSS45Z

0PSS45Z is the ICD-10-PCS code for a reposition procedure on the left thumb phalanx using a percutaneous endoscopic 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, other bones and closed reduction of fracture without internal fixation, phalanges of hand, the ICD-9-CM procedure titles it maps to (78.19 and 79.04).

For a different body part, codes include 0PSC45Z (right humeral head), 0PSD45Z (left humeral head), 0PSF45Z (right humeral shaft), 0PSG45Z (left humeral shaft), 0PSH45Z (right radius), 0PSJ45Z (left radius) and 9 more.

The same procedure with a different approach is coded 0PSS05Z (open) and 0PSS35Z (percutaneous).

With a different device, use 0PSS44Z (internal fixation device) and 0PSS4ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other O.R. 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.
