About 0M9B4ZX

0M9B4ZX is the ICD-10-PCS code for a drainage procedure on the left upper extremity bursa and ligament using a percutaneous endoscopic 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 other diagnostic procedures on muscle, tendon, fascia, and bursa, including that of hand, the ICD-9-CM procedure title it maps to (83.29).

For a different body part, codes include 0M904ZX (head and neck bursa and ligament), 0M914ZX (right shoulder bursa and ligament), 0M924ZX (left shoulder bursa and ligament), 0M934ZX (right elbow bursa and ligament), 0M944ZX (left elbow bursa and ligament), 0M954ZX (right wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0M9B0ZX (open) and 0M9B3ZX (percutaneous).

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.
