About 0CB7XZZ

0CB7XZZ is the ICD-10-PCS code for a excision procedure on the tongue using an external approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to partial glossectomy, the ICD-9-CM procedure title it maps to (25.2).

For a different body part, codes include 0CB0XZZ (upper lip), 0CB1XZZ (lower lip), 0CB2XZZ (hard palate), 0CB3XZZ (soft palate), 0CB4XZZ (buccal mucosa), 0CB5XZZ (upper gingiva) and 4 more.

The same procedure with a different approach is coded 0CB70ZZ (open) and 0CB73ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 137 (Mouth Procedures with CC/MCC), DRG 138 (Mouth Procedures without CC/MCC), DRG 625 (Thyroid, Parathyroid and Thyroglossal Procedures with MCC), DRG 626 (Thyroid, Parathyroid and Thyroglossal Procedures with CC) and DRG 627 (Thyroid, Parathyroid and Thyroglossal Procedures without CC/MCC), under the surgical categories “Mouth Procedures” and “Thyroid, Parathyroid and Thyroglossal Procedures”.

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