About 0K920ZZ
0K920ZZ is the ICD-10-PCS code for a drainage procedure on the right neck muscle using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to myotomy, the ICD-9-CM procedure title it maps to (83.02).
For a different body part, codes include 0K900ZZ (head muscle), 0K910ZZ (facial muscle), 0K930ZZ (left neck muscle), 0K940ZZ (tongue, palate, pharynx muscle), 0K950ZZ (right shoulder muscle), 0K960ZZ (left shoulder muscle) and 21 more.
The same procedure with a different approach is coded 0K923ZZ (percutaneous) and 0K924ZZ (percutaneous endoscopic).
With a different device, use 0K9200Z (drainage device).
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), DRG 145 (Other Ear, Nose, Mouth and Throat O.R.
