About 037434Z
037434Z is the ICD-10-PCS code for a dilation procedure on the left subclavian artery using a percutaneous approach with intraluminal device, drug-eluting. 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, insertion of drug-eluting stent(s) of other peripheral vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.45, 00.55 and 1 more).
For a different body part, codes include 037034Z (right internal mammary artery), 037134Z (left internal mammary artery), 037234Z (innominate artery), 037334Z (right subclavian artery), 037534Z (right axillary artery), 037634Z (left axillary artery) and 23 more.
The same procedure with a different approach is coded 037404Z (open) and 037444Z (percutaneous endoscopic).
With a different device, use 037435Z (intraluminal device, drug-eluting, two), 037436Z (intraluminal device, drug-eluting, three), 037437Z (intraluminal device, drug-eluting, four or more), 03743DZ (intraluminal device), 03743EZ (intraluminal device, two), 03743FZ (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 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Extracranial Procedures”, “Other Respiratory System O.R. Procedures”, “Other Vascular Procedures” and 8 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
