About 0SSF35Z
0SSF35Z is the ICD-10-PCS code for a reposition procedure on the right ankle joint using a percutaneous approach with external fixation device. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.
In plain terms, this corresponds to closed reduction of dislocation of ankle, the ICD-9-CM procedure title it maps to (79.77).
For a different body part, codes include 0SS935Z (right hip joint), 0SSB35Z (left hip joint), 0SSC35Z (right knee joint), 0SSD35Z (left knee joint), 0SSG35Z (left ankle joint), 0SSH35Z (right tarsal joint) and 7 more.
The same procedure with a different approach is coded 0SSF05Z (open), 0SSF45Z (percutaneous endoscopic) and 0SSFX5Z (external).
With a different device, use 0SSF34Z (internal fixation device) and 0SSF3ZZ (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.
