About 0C52XZZ

0C52XZZ is the ICD-10-PCS code for a destruction procedure on the hard palate using an external approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to local excision or destruction of lesion or tissue of bony palate, the ICD-9-CM procedure title it maps to (27.31).

For a different body part, codes include 0C50XZZ (upper lip), 0C51XZZ (lower lip), 0C53XZZ (soft palate), 0C54XZZ (buccal mucosa), 0C55XZZ (upper gingiva), 0C56XZZ (lower gingiva) and 4 more.

The same procedure with a different approach is coded 0C520ZZ (open) and 0C523ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 137 (Mouth Procedures with CC/MCC) and DRG 138 (Mouth Procedures without CC/MCC), under the surgical category “Mouth Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
