About 037G4EZ

037G4EZ is the ICD-10-PCS code for a dilation procedure on the intracranial artery using a percutaneous endoscopic approach with intraluminal device, 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, percutaneous angioplasty of intracranial vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.46, 00.62 and 1 more).

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

The same procedure with a different approach is coded 037G0EZ (open) and 037G3EZ (percutaneous).

With a different device, use 037G44Z (intraluminal device, drug-eluting), 037G45Z (intraluminal device, drug-eluting, two), 037G46Z (intraluminal device, drug-eluting, three), 037G47Z (intraluminal device, drug-eluting, four or more), 037G4DZ (intraluminal device), 037G4FZ (intraluminal device, three) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 020 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with MCC), DRG 021 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with CC), DRG 022 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage without CC/MCC), DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC) and DRG 025 (Craniotomy and Endovascular Intracranial Procedures with MCC), under the surgical categories “Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage”, “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures” and 3 more.

It was added in FY2017, effective October 1, 2016.
