About 3E1978Z

3E1978Z is the ICD-10-PCS code for a irrigation procedure on the nose using a via natural or artificial opening approach with irrigating substance. In ICD-10-PCS, irrigation means putting in or on a cleansing substance.

In plain terms, this corresponds to aspiration or lavage of nasal sinus through natural ostium and irrigation of nasal passages, the ICD-9-CM procedure titles it maps to (22.02 and 96.53).

For a different body part, codes include 3E1B78Z (ear), 3E1F78Z (respiratory tract), 3E1G78Z (upper GI), 3E1H78Z (lower GI), 3E1J78Z (biliary and pancreatic tract), 3E1K78Z (genitourinary tract) and 2 more.

The same procedure with a different approach is coded 3E1938Z (percutaneous) and 3E1988Z (via natural or artificial opening endoscopic).

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.
