About 03733Z1
03733Z1 is the ICD-10-PCS code for a dilation procedure on the right subclavian artery using a percutaneous approach (qualifier: drug-coated balloon). In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.
For a different body part, codes include 03703Z1 (right internal mammary artery), 03713Z1 (left internal mammary artery), 03723Z1 (innominate artery), 03743Z1 (left subclavian artery), 03753Z1 (right axillary artery), 03763Z1 (left axillary artery) and 6 more.
The same procedure with a different approach is coded 03730Z1 (open) and 03734Z1 (percutaneous endoscopic).
With a different device, use 03733D1 (intraluminal device).
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.
