About 0CBQXZX

0CBQXZX is the ICD-10-PCS code for a excision procedure on the adenoids 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 tonsils and adenoids, the ICD-9-CM procedure title it maps to (28.11).

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 0CBQ0ZX (open) and 0CBQ3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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