About 0CBNXZX

0CBNXZX is the ICD-10-PCS code for a excision procedure on the uvula using an external approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of uvula and soft palate, the ICD-9-CM procedure title it maps to (27.22).

For a different body part, codes include 0CB0XZX (upper lip), 0CB1XZX (lower lip), 0CB2XZX (hard palate), 0CB3XZX (soft palate), 0CB4XZX (buccal mucosa), 0CB5XZX (upper gingiva) and 4 more.

The same procedure with a different approach is coded 0CBN0ZX (open) and 0CBN3ZX (percutaneous).

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.
