About 3E0C3MZ
3E0C3MZ is the ICD-10-PCS code for a introduction procedure on the eye using a percutaneous approach with pigment. 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 tattooing of cornea, the ICD-9-CM procedure title it maps to (11.91).
The same procedure with a different approach is coded 3E0C7MZ (via natural or artificial opening) and 3E0CXMZ (external).
With a different device, use 3E0C33Z (anti-inflammatory), 3E0C3BZ (anesthetic agent), 3E0C3HZ (radioactive substance), 3E0C3KZ (other diagnostic substance), 3E0C3NZ (analgesics, hypnotics, sedatives) and 3E0C3TZ (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.
