About 0W9B003

0W9B003 is the ICD-10-PCS code for a drainage procedure on the left pleural cavity using an open approach with drainage device (qualifier: active mechanical clearance). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

For a different body part, codes include 0W99003 (right pleural cavity) and 0W9C003 (mediastinum).

The same procedure with a different approach is coded 0W9B303 (percutaneous) and 0W9B403 (percutaneous endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2027, effective October 1, 2026.
