About 0C5PXZZ

0C5PXZZ is the ICD-10-PCS code for a destruction procedure on the tonsils 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 other operations on tonsils and adenoids, the ICD-9-CM procedure title it maps to (28.99).

For a different body part, codes include 0C50XZZ (upper lip), 0C51XZZ (lower lip), 0C52XZZ (hard palate), 0C53XZZ (soft palate), 0C54XZZ (buccal mucosa), 0C55XZZ (upper gingiva) and 4 more.

The same procedure with a different approach is coded 0C5P0ZZ (open) and 0C5P3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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