0M990ZXDrainage of Right Upper Extremity Bursa and Ligament, Open Approach, Diagnostic

0M990ZX is the ICD-10-PCS code for a drainage procedure on the right upper extremity bursa and ligament using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to open biopsy of soft tissue, the ICD-9-CM procedure title it maps to (83.21).

For a different body part, codes include 0M900ZX (head and neck bursa and ligament), 0M910ZX (right shoulder bursa and ligament), 0M920ZX (left shoulder bursa and ligament), 0M930ZX (right elbow bursa and ligament), 0M940ZX (left elbow bursa and ligament), 0M950ZX (right wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0M993ZX (percutaneous) and 0M994ZX (percutaneous endoscopic).

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), DRG 502 (Soft Tissue Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Soft Tissue Procedures” and “Other Skin, Subcutaneous Tissue and Breast Procedures”.

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