About 001U477

001U477 is the ICD-10-PCS code for a bypass procedure on the spinal canal using a percutaneous endoscopic approach with autologous tissue substitute (qualifier: urinary tract). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

For a different body part, codes include 0016477 (cerebral ventricle).

The same procedure with a different approach is coded 001U077 (open) and 001U377 (percutaneous).

With a different device, use 001U4J7 (synthetic substitute) and 001U4K7 (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 028 (Spinal Procedures with MCC), DRG 029 (Spinal Procedures with CC or Spinal Neurostimulators), DRG 030 (Spinal Procedures without CC/MCC), DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), DRG 821 (Lymphoma and Leukemia with Major O.R. Procedures with CC) and DRG 822 (Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC), under the surgical categories “Spinal Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures”.

It was added in FY2019, effective October 1, 2018.
