About 0M900ZX

0M900ZX is the ICD-10-PCS code for a drainage procedure on the head and neck bursa and ligament using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from 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 0M910ZX (right shoulder bursa and ligament), 0M920ZX (left shoulder bursa and ligament), 0M930ZX (right elbow bursa and ligament), 0M940ZX (left elbow bursa and ligament), 0M950ZX (right wrist bursa and ligament), 0M960ZX (left wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0M903ZX (percutaneous) and 0M904ZX (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.
