About 0CB00ZX

0CB00ZX is the ICD-10-PCS code for a excision procedure on the upper lip 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 lip, the ICD-9-CM procedure title it maps to (27.23).

For a different body part, codes include 0CB10ZX (lower lip), 0CB20ZX (hard palate), 0CB30ZX (soft palate), 0CB40ZX (buccal mucosa), 0CB50ZX (upper gingiva), 0CB60ZX (lower gingiva) and 18 more.

The same procedure with a different approach is coded 0CB03ZX (percutaneous) and 0CB0XZX (external).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
