About 03784DZ

03784DZ is the ICD-10-PCS code for a dilation procedure on the left brachial artery using a percutaneous endoscopic approach with intraluminal device. 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 one vascular stent, angioplasty of other non-coronary vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.45, 39.50 and 1 more).

For a different body part, codes include 03704DZ (right internal mammary artery), 03714DZ (left internal mammary artery), 03724DZ (innominate artery), 03734DZ (right subclavian artery), 03744DZ (left subclavian artery), 03754DZ (right axillary artery) and 23 more.

The same procedure with a different approach is coded 03780DZ (open) and 03783DZ (percutaneous).

With a different device, use 037844Z (intraluminal device, drug-eluting), 037845Z (intraluminal device, drug-eluting, two), 037846Z (intraluminal device, drug-eluting, three), 037847Z (intraluminal device, drug-eluting, four or more), 03784EZ (intraluminal device, two), 03784FZ (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
