About 0W334ZZ

0W334ZZ is the ICD-10-PCS code for a control procedure on the oral cavity and throat using a percutaneous endoscopic approach. In ICD-10-PCS, control means stopping, or attempting to stop, postprocedural or other acute bleeding.

In plain terms, this corresponds to control of hemorrhage, not otherwise specified, the ICD-9-CM procedure title it maps to (39.98).

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. Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R.
