About 0W1G4JB

0W1G4JB is the ICD-10-PCS code for a bypass procedure on the peritoneal cavity using a percutaneous endoscopic approach with synthetic substitute (qualifier: left pleural cavity). 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 other operations of abdominal region, the ICD-9-CM procedure title it maps to (54.99).

For a different body part, codes include 0W194JB (right pleural cavity), 0W1B4JB (left pleural cavity) and 0W1J4JB (pelvic cavity).

The same procedure with a different approach is coded 0W1G0JB (open) and 0W1G3JB (percutaneous).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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