About 0K9540Z

0K9540Z is the ICD-10-PCS code for a drainage procedure on the right shoulder muscle 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 myotomy, the ICD-9-CM procedure title it maps to (83.02).

For a different body part, codes include 0K9040Z (head muscle), 0K9140Z (facial muscle), 0K9240Z (right neck muscle), 0K9340Z (left neck muscle), 0K9440Z (tongue, palate, pharynx muscle), 0K9640Z (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0K9500Z (open) and 0K9530Z (percutaneous).

With a different device, use 0K954ZZ (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 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”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures for Injuries”.

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