About 0CNN3ZZ

0CNN3ZZ is the ICD-10-PCS code for a release procedure on the uvula using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to repair of uvula, the ICD-9-CM procedure title it maps to (27.73).

For a different body part, codes include 0CN03ZZ (upper lip), 0CN13ZZ (lower lip), 0CN23ZZ (hard palate), 0CN33ZZ (soft palate), 0CN43ZZ (buccal mucosa), 0CN53ZZ (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0CNN0ZZ (open) and 0CNNXZZ (external).

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.
