About 3E09X3Z
3E09X3Z is the ICD-10-PCS code for a introduction procedure on the nose using an external approach with anti-inflammatory. 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 3E00X3Z (skin and mucous membranes), 3E0BX3Z (ear), 3E0CX3Z (eye) and 3E0DX3Z (mouth and pharynx).
The same procedure with a different approach is coded 3E0933Z (percutaneous) and 3E0973Z (via natural or artificial opening).
With a different device, use 3E09X4Z (serum, toxoid and vaccine), 3E09XBZ (anesthetic agent), 3E09XHZ (radioactive substance), 3E09XKZ (other diagnostic substance), 3E09XNZ (analgesics, hypnotics, sedatives) and 3E09XTZ (destructive agent).
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.
