About 3E0E77Z

3E0E77Z is the ICD-10-PCS code for a introduction procedure on the products of conception using a via natural or artificial opening approach with electrolytic and water balance substance. In ICD-10-PCS, introduction means putting in or on a therapeutic, diagnostic, nutritional, physiological, or prophylactic substance except blood or blood products.

In plain terms, this corresponds to Amnioinfusion, the ICD-9-CM procedure title it maps to (75.37).

For a different body part, codes include 3E0D77Z (mouth and pharynx), 3E0F77Z (respiratory tract), 3E0G77Z (upper GI), 3E0H77Z (lower GI), 3E0J77Z (biliary and pancreatic tract), 3E0K77Z (genitourinary tract) and 2 more.

The same procedure with a different approach is coded 3E0E37Z (percutaneous) and 3E0E87Z (via natural or artificial opening endoscopic).

With a different device, use 3E0E73Z (anti-inflammatory), 3E0E76Z (nutritional substance), 3E0E7BZ (anesthetic agent), 3E0E7HZ (radioactive substance), 3E0E7KZ (other diagnostic substance), 3E0E7NZ (analgesics, hypnotics, sedatives) and 1 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.
