About 3E09X29

3E09X29 is the ICD-10-PCS code for a introduction procedure on the nose using an external approach with anti-infective (qualifier: other anti-infective). 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 3E00X29 (skin and mucous membranes), 3E0BX29 (ear), 3E0CX29 (eye) and 3E0DX29 (mouth and pharynx).

The same procedure with a different approach is coded 3E09329 (percutaneous) and 3E09729 (via natural or artificial opening).

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.
