About 03RG47Z

03RG47Z is the ICD-10-PCS code for a replacement procedure on the intracranial artery using a percutaneous endoscopic approach with autologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to resection of vessel with replacement, intracranial vessels, the ICD-9-CM procedure title it maps to (38.41).

For a different body part, codes include 03R047Z (right internal mammary artery), 03R147Z (left internal mammary artery), 03R247Z (innominate artery), 03R347Z (right subclavian artery), 03R447Z (left subclavian artery), 03R547Z (right axillary artery) and 23 more.

The same procedure with a different approach is coded 03RG07Z (open).

With a different device, use 03RG4JZ (synthetic substitute) and 03RG4KZ (nonautologous tissue substitute).

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 2 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
