About 0016477

0016477 is the ICD-10-PCS code for a bypass procedure on the cerebral ventricle 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.

In plain terms, this corresponds to ventricular shunt to urinary system, the ICD-9-CM procedure title it maps to (02.35).

For a different body part, codes include 001U477 (spinal canal).

The same procedure with a different approach is coded 0016077 (open) and 0016377 (percutaneous).

With a different device, use 00164J7 (synthetic substitute) and 00164K7 (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 031 (Ventricular Shunt Procedures with MCC), DRG 032 (Ventricular Shunt Procedures with CC), DRG 033 (Ventricular Shunt 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 “Ventricular Shunt Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures”, “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures” and 2 more.

It was added in FY2018, effective October 1, 2017.
