About 0CS20ZZ
0CS20ZZ is the ICD-10-PCS code for a reposition procedure on the hard palate using an open approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.
In plain terms, this corresponds to other plastic repair of palate, the ICD-9-CM procedure title it maps to (27.69).
For a different body part, codes include 0CS00ZZ (upper lip), 0CS10ZZ (lower lip), 0CS30ZZ (soft palate), 0CS70ZZ (tongue), 0CSB0ZZ (right parotid duct), 0CSC0ZZ (left parotid duct) and 5 more.
The same procedure with a different approach is coded 0CS2XZZ (external).
It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), 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 categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures” and “Other Skin, Subcutaneous Tissue and Breast Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
