About 0CQQ3ZZ

0CQQ3ZZ is the ICD-10-PCS code for a repair procedure on the adenoids using a percutaneous approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

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 0CQ03ZZ (upper lip), 0CQ13ZZ (lower lip), 0CQ23ZZ (hard palate), 0CQ33ZZ (soft palate), 0CQ43ZZ (buccal mucosa), 0CQ53ZZ (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0CQQ0ZZ (open) and 0CQQXZZ (external).

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.
