About 0CT80ZZ

0CT80ZZ is the ICD-10-PCS code for a resection procedure on the right parotid gland using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to complete sialoadenectomy, the ICD-9-CM procedure title it maps to (26.32).

For a different body part, codes include 0CT00ZZ (upper lip), 0CT10ZZ (lower lip), 0CT20ZZ (hard palate), 0CT30ZZ (soft palate), 0CT70ZZ (tongue), 0CT90ZZ (left parotid gland) and 15 more.

It is an operating-room procedure in the MS-DRG logic for DRG 139 (Salivary Gland Procedures), under the surgical category “Salivary Gland Procedures”.

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