About 0CB30ZX

0CB30ZX is the ICD-10-PCS code for a excision procedure on the soft palate using an open 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 0CB00ZX (upper lip), 0CB10ZX (lower lip), 0CB20ZX (hard palate), 0CB40ZX (buccal mucosa), 0CB50ZX (upper gingiva), 0CB60ZX (lower gingiva) and 18 more.

The same procedure with a different approach is coded 0CB33ZX (percutaneous) and 0CB3XZX (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.
