About 0CN53ZZ
0CN53ZZ is the ICD-10-PCS code for a release procedure on the upper gingiva using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to exposure of tooth, the ICD-9-CM procedure title it maps to (24.6).
For a different body part, codes include 0CN03ZZ (upper lip), 0CN13ZZ (lower lip), 0CN23ZZ (hard palate), 0CN33ZZ (soft palate), 0CN43ZZ (buccal mucosa), 0CN63ZZ (lower gingiva) and 18 more.
The same procedure with a different approach is coded 0CN50ZZ (open) and 0CN5XZZ (external).
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.
