About 001U3K2

001U3K2 is the ICD-10-PCS code for a bypass procedure on the spinal canal using a percutaneous approach with nonautologous tissue substitute (qualifier: atrium). 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 00163K2 (cerebral ventricle).

The same procedure with a different approach is coded 001U0K2 (open) and 001U4K2 (percutaneous endoscopic).

With a different device, use 001U372 (autologous tissue substitute) and 001U3J2 (synthetic 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.
