About 0K9300Z

0K9300Z is the ICD-10-PCS code for a drainage procedure on the left neck muscle using an open approach with drainage device. 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 0K9000Z (head muscle), 0K9100Z (facial muscle), 0K9200Z (right neck muscle), 0K9400Z (tongue, palate, pharynx muscle), 0K9500Z (right shoulder muscle), 0K9600Z (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0K9330Z (percutaneous) and 0K9340Z (percutaneous endoscopic).

With a different device, use 0K930ZZ (no 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.
