About 3E0DXTZ
3E0DXTZ is the ICD-10-PCS code for a introduction procedure on the mouth and pharynx using an external approach with destructive agent. 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 injection or infusion of other therapeutic or prophylactic substance, the ICD-9-CM procedure title it maps to (99.29).
For a different body part, codes include 3E00XTZ (skin and mucous membranes), 3E09XTZ (nose), 3E0BXTZ (ear) and 3E0CXTZ (eye).
The same procedure with a different approach is coded 3E0D3TZ (percutaneous) and 3E0D7TZ (via natural or artificial opening).
With a different device, use 3E0DX3Z (anti-inflammatory), 3E0DX4Z (serum, toxoid and vaccine), 3E0DX6Z (nutritional substance), 3E0DX7Z (electrolytic and water balance substance), 3E0DXBZ (anesthetic agent), 3E0DXHZ (radioactive substance) and 3 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.
