About 0FN97ZZ

0FN97ZZ is the ICD-10-PCS code for a release procedure on the common bile duct using a via natural or artificial opening 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 0FN57ZZ (right hepatic duct), 0FN67ZZ (left hepatic duct), 0FN77ZZ (hepatic duct, common), 0FN87ZZ (cystic duct), 0FNC7ZZ (ampulla of vater), 0FND7ZZ (pancreatic duct) and 1 more.

The same procedure with a different approach is coded 0FN90ZZ (open), 0FN93ZZ (percutaneous), 0FN94ZZ (percutaneous endoscopic) and 0FN98ZZ (via natural or artificial opening endoscopic).

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.
