About 3E0BXBZ

3E0BXBZ is the ICD-10-PCS code for a introduction procedure on the ear using an external approach with anesthetic 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 into inner ear and injection of tympanum, the ICD-9-CM procedure titles it maps to (20.72 and 20.94).

For a different body part, codes include 3E00XBZ (skin and mucous membranes), 3E09XBZ (nose), 3E0CXBZ (eye) and 3E0DXBZ (mouth and pharynx).

The same procedure with a different approach is coded 3E0B3BZ (percutaneous) and 3E0B7BZ (via natural or artificial opening).

With a different device, use 3E0BX3Z (anti-inflammatory), 3E0BXHZ (radioactive substance), 3E0BXKZ (other diagnostic substance), 3E0BXNZ (analgesics, hypnotics, sedatives) and 3E0BXTZ (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.
