About 04N03ZZ
04N03ZZ is the ICD-10-PCS code for a release procedure on the abdominal aorta using a percutaneous 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 04N13ZZ (celiac artery), 04N23ZZ (gastric artery), 04N33ZZ (hepatic artery), 04N43ZZ (splenic artery), 04N53ZZ (superior mesenteric artery), 04N63ZZ (right colic artery) and 24 more.
The same procedure with a different approach is coded 04N00ZZ (open) and 04N04ZZ (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) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
