About 0SWC45Z
0SWC45Z is the ICD-10-PCS code for a revision procedure on the right knee joint using a percutaneous endoscopic approach with external fixation device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.
In plain terms, this corresponds to other arthrotomy, knee, the ICD-9-CM procedure title it maps to (80.16).
For a different body part, codes include 0SW945Z (right hip joint), 0SWB45Z (left hip joint), 0SWD45Z (left knee joint), 0SWF45Z (right ankle joint), 0SWG45Z (left ankle joint), 0SWH45Z (right tarsal joint) and 7 more.
The same procedure with a different approach is coded 0SWC05Z (open), 0SWC35Z (percutaneous) and 0SWCX5Z (external).
With a different device, use 0SWC40Z (drainage device), 0SWC43Z (infusion device), 0SWC44Z (internal fixation device), 0SWC47Z (autologous tissue substitute), 0SWC48Z (spacer), 0SWC4JZ (synthetic substitute) and 1 more.
It is an operating-room procedure in the MS-DRG logic for DRG 400 (Knee Procedures with Principal Diagnosis of Infection), DRG 488 (Knee Procedures without Principal Diagnosis of Infection with CC/MCC), DRG 489 (Knee Procedures without Principal Diagnosis of Infection 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.
