About 0D164Z4
0D164Z4 is the ICD-10-PCS code for a bypass procedure on the stomach using a percutaneous endoscopic approach (qualifier: cutaneous). 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 gastrostomy, the ICD-9-CM procedure title it maps to (43.19).
For a different body part, codes include 0D114Z4 (esophagus, upper), 0D124Z4 (esophagus, middle), 0D134Z4 (esophagus, lower), 0D154Z4 (esophagus), 0D184Z4 (small intestine), 0D194Z4 (duodenum) and 8 more.
The same procedure with a different approach is coded 0D160Z4 (open) and 0D168Z4 (via natural or artificial opening endoscopic).
With a different device, use 0D16474 (autologous tissue substitute), 0D164J4 (synthetic substitute) and 0D164K4 (nonautologous tissue substitute).
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.
