About 037K3EZ
037K3EZ is the ICD-10-PCS code for a dilation procedure on the right internal carotid artery using a percutaneous 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 03703EZ (right internal mammary artery), 03713EZ (left internal mammary artery), 03723EZ (innominate artery), 03733EZ (right subclavian artery), 03743EZ (left subclavian artery), 03753EZ (right axillary artery) and 23 more.
The same procedure with a different approach is coded 037K0EZ (open) and 037K4EZ (percutaneous endoscopic).
With a different device, use 037K34Z (intraluminal device, drug-eluting), 037K35Z (intraluminal device, drug-eluting, two), 037K36Z (intraluminal device, drug-eluting, three), 037K37Z (intraluminal device, drug-eluting, four or more), 037K3DZ (intraluminal device), 037K3FZ (intraluminal device, three) and 2 more.
It is an operating-room procedure in the MS-DRG logic for DRG 034 (Carotid Artery Stent Procedures with MCC), DRG 035 (Carotid Artery Stent Procedures with CC), DRG 036 (Carotid Artery Stent 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 “Carotid Artery Stent Procedures”, “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and 1 more.
It was added in FY2017, effective October 1, 2016.
