About 037Q3ZZ
037Q3ZZ is the ICD-10-PCS code for a dilation procedure on the left vertebral artery using a percutaneous approach. 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 and percutaneous angioplasty of extracranial vessel(s), the ICD-9-CM procedure titles it maps to (00.40 and 00.61).
For a different body part, codes include 03703ZZ (right internal mammary artery), 03713ZZ (left internal mammary artery), 03723ZZ (innominate artery), 03733ZZ (right subclavian artery), 03743ZZ (left subclavian artery), 03753ZZ (right axillary artery) and 23 more.
The same procedure with a different approach is coded 037Q0ZZ (open) and 037Q4ZZ (percutaneous endoscopic).
With a different device, use 037Q34Z (intraluminal device, drug-eluting), 037Q35Z (intraluminal device, drug-eluting, two), 037Q36Z (intraluminal device, drug-eluting, three), 037Q37Z (intraluminal device, drug-eluting, four or more), 037Q3DZ (intraluminal device), 037Q3EZ (intraluminal device, two) 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 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 “Extracranial Procedures”, “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and 1 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
