About 0MJX4ZZ

0MJX4ZZ is the ICD-10-PCS code for a inspection procedure on the upper bursa and ligament using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other diagnostic procedures on joint structures, the ICD-9-CM procedure title it maps to (81.98).

For a different body part, codes include 0MJY4ZZ (lower bursa and ligament).

The same procedure with a different approach is coded 0MJX0ZZ (open), 0MJX3ZZ (percutaneous) and 0MJXXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 477 (Biopsies of Musculoskeletal System and Connective Tissue with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 478 (Biopsies of Musculoskeletal System and Connective Tissue with CC) and DRG 479 (Biopsies of Musculoskeletal System and Connective Tissue without CC/MCC), under the surgical category “Biopsies of Musculoskeletal System and Connective Tissue”.

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