About 0S9G0ZZ
0S9G0ZZ is the ICD-10-PCS code for a drainage procedure on the left ankle joint using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other arthrotomy, ankle, the ICD-9-CM procedure title it maps to (80.17).
For a different body part, codes include 0S900ZZ (lumbar vertebral joint), 0S920ZZ (lumbar vertebral disc), 0S930ZZ (lumbosacral joint), 0S940ZZ (lumbosacral disc), 0S950ZZ (sacrococcygeal joint), 0S960ZZ (coccygeal joint) and 15 more.
The same procedure with a different approach is coded 0S9G3ZZ (percutaneous) and 0S9G4ZZ (percutaneous endoscopic).
With a different device, use 0S9G00Z (drainage device).
