About 3E09XTZ
3E09XTZ is the ICD-10-PCS code for a introduction procedure on the nose 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), 3E0BXTZ (ear), 3E0CXTZ (eye) and 3E0DXTZ (mouth and pharynx).
The same procedure with a different approach is coded 3E093TZ (percutaneous) and 3E097TZ (via natural or artificial opening).
With a different device, use 3E09X3Z (anti-inflammatory), 3E09X4Z (serum, toxoid and vaccine), 3E09XBZ (anesthetic agent), 3E09XHZ (radioactive substance), 3E09XKZ (other diagnostic substance) and 3E09XNZ (analgesics, hypnotics, sedatives).
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.
