About 0MSW4ZZ

0MSW4ZZ is the ICD-10-PCS code for a reposition procedure on the left lower extremity bursa and ligament using a percutaneous endoscopic approach. 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 other operations on muscle, tendon, fascia, and bursa, the ICD-9-CM procedure title it maps to (83.99).

For a different body part, codes include 0MS04ZZ (head and neck bursa and ligament), 0MS14ZZ (right shoulder bursa and ligament), 0MS24ZZ (left shoulder bursa and ligament), 0MS34ZZ (right elbow bursa and ligament), 0MS44ZZ (left elbow bursa and ligament), 0MS54ZZ (right wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0MSW0ZZ (open).

It is an operating-room procedure in the MS-DRG logic for DRG 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC) and DRG 502 (Soft Tissue Procedures without CC/MCC), under the surgical category “Soft Tissue Procedures”.

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