About 0MB00ZX

0MB00ZX is the ICD-10-PCS code for a excision procedure on the head and neck bursa and ligament 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 biopsy of joint structure, other specified sites and open biopsy of soft tissue, the ICD-9-CM procedure titles it maps to (80.39 and 83.21).

For a different body part, codes include 0MB10ZX (right shoulder bursa and ligament), 0MB20ZX (left shoulder bursa and ligament), 0MB30ZX (right elbow bursa and ligament), 0MB40ZX (left elbow bursa and ligament), 0MB50ZX (right wrist bursa and ligament), 0MB60ZX (left wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0MB03ZX (percutaneous) and 0MB04ZX (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.
