About 0CB6XZX

0CB6XZX is the ICD-10-PCS code for a excision procedure on the lower gingiva 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 gum, the ICD-9-CM procedure title it maps to (24.11).

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 0CB60ZX (open) and 0CB63ZX (percutaneous).

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.
