About 037G3ZZ
037G3ZZ is the ICD-10-PCS code for a dilation procedure on the intracranial 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 intracranial vessel(s), the ICD-9-CM procedure titles it maps to (00.40 and 00.62).
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 037G0ZZ (open) and 037G4ZZ (percutaneous endoscopic).
With a different device, use 037G34Z (intraluminal device, drug-eluting), 037G35Z (intraluminal device, drug-eluting, two), 037G36Z (intraluminal device, drug-eluting, three), 037G37Z (intraluminal device, drug-eluting, four or more), 037G3DZ (intraluminal device), 037G3EZ (intraluminal device, two) 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 has been valid since ICD-10-PCS took effect on October 1, 2015.
