About 0CMN0ZZ

0CMN0ZZ is the ICD-10-PCS code for a reattachment procedure on the uvula using an open approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

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 0CM00ZZ (upper lip), 0CM10ZZ (lower lip), 0CM30ZZ (soft palate) and 0CM70ZZ (tongue).

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.
