About 3E0F77Z
3E0F77Z is the ICD-10-PCS code for a introduction procedure on the respiratory tract 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 respiratory medication administered by nebulizer, the ICD-9-CM procedure title it maps to (93.94).
For a different body part, codes include 3E0D77Z (mouth and pharynx), 3E0E77Z (products of conception), 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 3E0F37Z (percutaneous) and 3E0F87Z (via natural or artificial opening endoscopic).
With a different device, use 3E0F73Z (anti-inflammatory), 3E0F76Z (nutritional substance), 3E0F7BZ (anesthetic agent), 3E0F7HZ (radioactive substance), 3E0F7KZ (other diagnostic substance), 3E0F7NZ (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.
