About 0CRWXK1

0CRWXK1 is the ICD-10-PCS code for a replacement procedure on the upper tooth using an external approach with nonautologous tissue substitute (qualifier: multiple). In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to other dental restoration, the ICD-9-CM procedure title it maps to (23.49).

For a different body part, codes include 0CRXXK1 (lower tooth).

The same procedure with a different approach is coded 0CRW0K1 (open).

With a different device, use 0CRWX71 (autologous tissue substitute) and 0CRWXJ1 (synthetic substitute).

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.
