About 0CBP0ZX

0CBP0ZX is the ICD-10-PCS code for a excision procedure on the tonsils 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 tonsils and adenoids, the ICD-9-CM procedure title it maps to (28.11).

For a different body part, codes include 0CB00ZX (upper lip), 0CB10ZX (lower lip), 0CB20ZX (hard palate), 0CB30ZX (soft palate), 0CB40ZX (buccal mucosa), 0CB50ZX (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0CBP3ZX (percutaneous) and 0CBPXZX (external).

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.
