About 0DNU4ZZ

0DNU4ZZ is the ICD-10-PCS code for a release procedure on the omentum using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to laparoscopic lysis of peritoneal adhesions, the ICD-9-CM procedure title it maps to (54.51).

For a different body part, codes include 0DN14ZZ (esophagus, upper), 0DN24ZZ (esophagus, middle), 0DN34ZZ (esophagus, lower), 0DN44ZZ (esophagogastric junction), 0DN54ZZ (esophagus), 0DN64ZZ (stomach) and 20 more.

The same procedure with a different approach is coded 0DNU0ZZ (open) and 0DNU3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 335 (Peritoneal Adhesiolysis with MCC), DRG 336 (Peritoneal Adhesiolysis with CC), DRG 337 (Peritoneal Adhesiolysis without CC/MCC), DRG 423 (Other Hepatobiliary or Pancreas O.R. Procedures with MCC), DRG 424 (Other Hepatobiliary or Pancreas O.R. Procedures with CC) and DRG 425 (Other Hepatobiliary or Pancreas O.R. Procedures without CC/MCC), under the surgical categories “Peritoneal Adhesiolysis”, “Other Hepatobiliary or Pancreas O.R. Procedures”, “Other Kidney and Urinary Tract Procedures” and 3 more.

It was added in FY2018, effective October 1, 2017.
