About 0L9P40Z

0L9P40Z is the ICD-10-PCS code for a drainage procedure on the left lower leg tendon 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 exploration of tendon sheath, the ICD-9-CM procedure title it maps to (83.01).

For a different body part, codes include 0L9040Z (head and neck tendon), 0L9140Z (right shoulder tendon), 0L9240Z (left shoulder tendon), 0L9340Z (right upper arm tendon), 0L9440Z (left upper arm tendon), 0L9540Z (right lower arm and wrist tendon) and 21 more.

The same procedure with a different approach is coded 0L9P00Z (open) and 0L9P30Z (percutaneous).

With a different device, use 0L9P4ZZ (no device).

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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Soft Tissue Procedures” and “Other O.R. Procedures for Injuries”.

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