About 03714EZ
03714EZ is the ICD-10-PCS code for a dilation procedure on the left internal mammary 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, angioplasty of other non-coronary vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.46, 39.50 and 1 more).
For a different body part, codes include 03704EZ (right internal mammary artery), 03724EZ (innominate artery), 03734EZ (right subclavian artery), 03744EZ (left subclavian artery), 03754EZ (right axillary artery), 03764EZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03710EZ (open) and 03713EZ (percutaneous).
With a different device, use 037144Z (intraluminal device, drug-eluting), 037145Z (intraluminal device, drug-eluting, two), 037146Z (intraluminal device, drug-eluting, three), 037147Z (intraluminal device, drug-eluting, four or more), 03714DZ (intraluminal device), 03714FZ (intraluminal device, three) and 2 more.
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 was added in FY2017, effective October 1, 2016.
