About 04N63ZZ
04N63ZZ is the ICD-10-PCS code for a release procedure on the right colic artery 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 04N03ZZ (abdominal aorta), 04N13ZZ (celiac artery), 04N23ZZ (gastric artery), 04N33ZZ (hepatic artery), 04N43ZZ (splenic artery), 04N53ZZ (superior mesenteric artery) and 24 more.
The same procedure with a different approach is coded 04N60ZZ (open) and 04N64ZZ (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.
