About 3E0D3BZ

3E0D3BZ is the ICD-10-PCS code for a introduction procedure on the mouth and pharynx using a percutaneous 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 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 3E013BZ (subcutaneous tissue), 3E023BZ (muscle), 3E093BZ (nose), 3E0B3BZ (ear), 3E0C3BZ (eye), 3E0E3BZ (products of conception) and 18 more.

The same procedure with a different approach is coded 3E0D7BZ (via natural or artificial opening) and 3E0DXBZ (external).

With a different device, use 3E0D33Z (anti-inflammatory), 3E0D34Z (serum, toxoid and vaccine), 3E0D36Z (nutritional substance), 3E0D37Z (electrolytic and water balance substance), 3E0D3HZ (radioactive substance), 3E0D3KZ (other diagnostic substance) and 3 more.

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.
