About 0CSXX52

0CSXX52 is the ICD-10-PCS code for a reposition procedure on the lower tooth using an external approach with external fixation device (qualifier: all). 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 application of orthodontic appliance, the ICD-9-CM procedure title it maps to (24.7).

For a different body part, codes include 0CSWX52 (upper tooth).

The same procedure with a different approach is coded 0CSX052 (open).

With a different device, use 0CSXXZ2 (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.
