About 0M9040Z

0M9040Z is the ICD-10-PCS code for a drainage procedure on the head and neck bursa and ligament using a percutaneous endoscopic approach with drainage device. 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 arthrotomy, other specified sites and aspiration of bursa, the ICD-9-CM procedure titles it maps to (80.19 and 83.94).

For a different body part, codes include 0M9140Z (right shoulder bursa and ligament), 0M9240Z (left shoulder bursa and ligament), 0M9340Z (right elbow bursa and ligament), 0M9440Z (left elbow bursa and ligament), 0M9540Z (right wrist bursa and ligament), 0M9640Z (left wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0M9000Z (open) and 0M9030Z (percutaneous).

With a different device, use 0M904ZZ (no device).

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.
