About 06NF0ZZ

06NF0ZZ is the ICD-10-PCS code for a release procedure on the right external iliac vein using an open 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 Freeing of vessel, the ICD-9-CM procedure title it maps to (39.91).

For a different body part, codes include 06N00ZZ (inferior vena cava), 06N10ZZ (splenic vein), 06N20ZZ (gastric vein), 06N30ZZ (esophageal vein), 06N40ZZ (hepatic vein), 06N50ZZ (superior mesenteric vein) and 17 more.

The same procedure with a different approach is coded 06NF3ZZ (percutaneous) and 06NF4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC), DRG 254 (Other Vascular Procedures without CC/MCC), DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC) and DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), under the surgical categories “Other Vascular Procedures” and “Other Digestive System O.R. Procedures”.

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