About 0WBLXZX

0WBLXZX is the ICD-10-PCS code for a excision procedure on the lower back using an external approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to closed biopsy of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.11).

For a different body part, codes include 0WB0XZX (head), 0WB2XZX (face), 0WB3XZX (oral cavity and throat), 0WB4XZX (upper jaw), 0WB5XZX (lower jaw), 0WB6XZX (neck) and 5 more.

The same procedure with a different approach is coded 0WBL0ZX (open), 0WBL3ZX (percutaneous) and 0WBL4ZX (percutaneous endoscopic).

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.
