About 0XB50ZX

0XB50ZX is the ICD-10-PCS code for a excision procedure on the left axilla using an open 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 other diagnostic procedures on skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.19).

For a different body part, codes include 0XB20ZX (right shoulder region), 0XB30ZX (left shoulder region), 0XB40ZX (right axilla), 0XB60ZX (right upper extremity), 0XB70ZX (left upper extremity), 0XB80ZX (right upper arm) and 9 more.

The same procedure with a different approach is coded 0XB53ZX (percutaneous) and 0XB54ZX (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.
