About 3E1H88X

3E1H88X is the ICD-10-PCS code for a irrigation procedure on the lower GI using a via natural or artificial opening endoscopic approach with irrigating substance (qualifier: diagnostic). In ICD-10-PCS, irrigation means putting in or on a cleansing substance.

In plain terms, this corresponds to gastric lavage, the ICD-9-CM procedure title it maps to (96.33).

For a different body part, codes include 3E1988X (nose), 3E1B88X (ear), 3E1F88X (respiratory tract), 3E1G88X (upper GI), 3E1J88X (biliary and pancreatic tract), 3E1K88X (genitourinary tract) and 2 more.

The same procedure with a different approach is coded 3E1H38X (percutaneous) and 3E1H78X (via natural or artificial opening).

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.
