About 0S9540Z
0S9540Z is the ICD-10-PCS code for a drainage procedure on the sacrococcygeal joint 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 Arthrocentesis, the ICD-9-CM procedure title it maps to (81.91).
For a different body part, codes include 0S9040Z (lumbar vertebral joint), 0S9240Z (lumbar vertebral disc), 0S9340Z (lumbosacral joint), 0S9440Z (lumbosacral disc), 0S9640Z (coccygeal joint), 0S9740Z (right sacroiliac joint) and 15 more.
The same procedure with a different approach is coded 0S9500Z (open) and 0S9530Z (percutaneous).
With a different device, use 0S954ZZ (no device).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
