About 0HPU77Z

0HPU77Z is the ICD-10-PCS code for a removal procedure on the left breast using a via natural or artificial opening approach with autologous tissue substitute. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to Mastotomy, the ICD-9-CM procedure title it maps to (85.0).

For a different body part, codes include 0HPT77Z (right breast).

The same procedure with a different approach is coded 0HPU07Z (open), 0HPU37Z (percutaneous) and 0HPU87Z (via natural or artificial opening endoscopic).

With a different device, use 0HPU70Z (drainage device), 0HPU71Z (radioactive element), 0HPU7JZ (synthetic substitute), 0HPU7KZ (nonautologous tissue substitute), 0HPU7NZ (tissue expander) and 0HPU7YZ (other device).

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.
