About 0FN58ZZ

0FN58ZZ is the ICD-10-PCS code for a release procedure on the right hepatic duct using a via natural or artificial opening 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 other lysis of peritoneal adhesions, the ICD-9-CM procedure title it maps to (54.59).

For a different body part, codes include 0FN48ZZ (gallbladder), 0FN68ZZ (left hepatic duct), 0FN78ZZ (hepatic duct, common), 0FN88ZZ (cystic duct), 0FN98ZZ (common bile duct), 0FNC8ZZ (ampulla of vater) and 3 more.

The same procedure with a different approach is coded 0FN50ZZ (open), 0FN53ZZ (percutaneous), 0FN54ZZ (percutaneous endoscopic) and 0FN57ZZ (via natural or artificial opening).

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 Endocrine, Nutritional and Metabolic O.R. Procedures” and 4 more.

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