About 001U4J6
001U4J6 is the ICD-10-PCS code for a bypass procedure on the spinal canal using a percutaneous endoscopic approach with synthetic substitute (qualifier: peritoneal cavity). 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 00164J6 (cerebral ventricle).
The same procedure with a different approach is coded 001U0J6 (open) and 001U3J6 (percutaneous).
With a different device, use 001U476 (autologous tissue substitute) and 001U4K6 (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.
