About 037P4EZ
037P4EZ is the ICD-10-PCS code for a dilation procedure on the right vertebral artery using a percutaneous endoscopic approach with intraluminal device, two. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.
In plain terms, this corresponds to procedure on single vessel, insertion of two vascular stents, percutaneous angioplasty of extracranial vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.46, 00.61 and 1 more).
For a different body part, codes include 03704EZ (right internal mammary artery), 03714EZ (left internal mammary artery), 03724EZ (innominate artery), 03734EZ (right subclavian artery), 03744EZ (left subclavian artery), 03754EZ (right axillary artery) and 23 more.
The same procedure with a different approach is coded 037P0EZ (open) and 037P3EZ (percutaneous).
With a different device, use 037P44Z (intraluminal device, drug-eluting), 037P45Z (intraluminal device, drug-eluting, two), 037P46Z (intraluminal device, drug-eluting, three), 037P47Z (intraluminal device, drug-eluting, four or more), 037P4DZ (intraluminal device), 037P4FZ (intraluminal device, three) and 2 more.
It is an operating-room procedure in the MS-DRG logic for DRG 037 (Extracranial Procedures with MCC), DRG 038 (Extracranial Procedures with CC), DRG 039 (Extracranial Procedures without CC/MCC), 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 categories “Extracranial Procedures”, “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and 1 more.
It was added in FY2017, effective October 1, 2016.
