About 3C1ZX8Z

3C1ZX8Z is the ICD-10-PCS code for a irrigation procedure on the none using an external approach with irrigating substance. In ICD-10-PCS, irrigation means putting in or on a cleansing substance.

In plain terms, this corresponds to irrigation and exploration of ventricular shunt, other irrigation of (naso-)gastric tube, irrigation of cholecystostomy and other biliary tube and 8 more, the ICD-9-CM procedure titles it maps to (02.41, 96.34, 96.41 and 8 more).

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.
