About 0CSN0ZZ

0CSN0ZZ is the ICD-10-PCS code for a reposition procedure on the uvula using an open approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

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 0CS00ZZ (upper lip), 0CS10ZZ (lower lip), 0CS20ZZ (hard palate), 0CS30ZZ (soft palate), 0CS70ZZ (tongue), 0CSB0ZZ (right parotid duct) and 5 more.

The same procedure with a different approach is coded 0CSNXZZ (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.
