About 0MML4ZZ

0MML4ZZ is the ICD-10-PCS code for a reattachment procedure on the right hip bursa and ligament using a percutaneous endoscopic approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

In plain terms, this corresponds to other repair of joint, the ICD-9-CM procedure title it maps to (81.96).

For a different body part, codes include 0MM04ZZ (head and neck bursa and ligament), 0MM14ZZ (right shoulder bursa and ligament), 0MM24ZZ (left shoulder bursa and ligament), 0MM34ZZ (right elbow bursa and ligament), 0MM44ZZ (left elbow bursa and ligament), 0MM54ZZ (right wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0MML0ZZ (open).

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) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical category “Other Musculoskeletal System and Connective Tissue O.R. Procedures”.

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