About 0SSLX4Z

0SSLX4Z is the ICD-10-PCS code for a reposition procedure on the left tarsometatarsal joint using an external approach with internal 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 foot and toe, the ICD-9-CM procedure title it maps to (79.78).

For a different body part, codes include 0SS0X4Z (lumbar vertebral joint), 0SS3X4Z (lumbosacral joint), 0SS5X4Z (sacrococcygeal joint), 0SS6X4Z (coccygeal joint), 0SS7X4Z (right sacroiliac joint), 0SS8X4Z (left sacroiliac joint) and 13 more.

The same procedure with a different approach is coded 0SSL04Z (open), 0SSL34Z (percutaneous) and 0SSL44Z (percutaneous endoscopic).

With a different device, use 0SSLX5Z (external fixation device) and 0SSLXZZ (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.
