About 037M35Z

037M35Z is the ICD-10-PCS code for a dilation procedure on the right external carotid artery using a percutaneous approach with intraluminal device, drug-eluting, 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, 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, 00.46, 00.55 and 1 more).

For a different body part, codes include 037035Z (right internal mammary artery), 037135Z (left internal mammary artery), 037235Z (innominate artery), 037335Z (right subclavian artery), 037435Z (left subclavian artery), 037535Z (right axillary artery) and 23 more.

The same procedure with a different approach is coded 037M05Z (open) and 037M45Z (percutaneous endoscopic).

With a different device, use 037M34Z (intraluminal device, drug-eluting), 037M36Z (intraluminal device, drug-eluting, three), 037M37Z (intraluminal device, drug-eluting, four or more), 037M3DZ (intraluminal device), 037M3EZ (intraluminal device, two), 037M3FZ (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.
