About 3E09X4Z

3E09X4Z is the ICD-10-PCS code for a introduction procedure on the nose using an external approach with serum, toxoid and vaccine. 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 3E00X4Z (skin and mucous membranes) and 3E0DX4Z (mouth and pharynx).

The same procedure with a different approach is coded 3E0934Z (percutaneous) and 3E0974Z (via natural or artificial opening).

With a different device, use 3E09X3Z (anti-inflammatory), 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.
