About 0D188ZQ

0D188ZQ is the ICD-10-PCS code for a bypass procedure on the small intestine using a via natural or artificial opening endoscopic approach (qualifier: anus). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

With a different device, use 0D1887Q (autologous tissue substitute), 0D188JQ (synthetic substitute) and 0D188KQ (nonautologous tissue substitute).
