About 0W33XZZ

0W33XZZ is the ICD-10-PCS code for a control procedure on the oral cavity and throat using an external 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).

The same procedure with a different approach is coded 0W330ZZ (open), 0W333ZZ (percutaneous), 0W334ZZ (percutaneous endoscopic), 0W337ZZ (via natural or artificial opening) and 0W338ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), under the surgical categories “Major Chest Procedures”, “Other Circulatory System O.R. Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures” and 4 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
