About 0P940ZZ

0P940ZZ is the ICD-10-PCS code for a drainage procedure on the thoracic vertebra using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of bone without division, other bones, the ICD-9-CM procedure title it maps to (77.19).

The same procedure with a different approach is coded 0P943ZZ (percutaneous) and 0P944ZZ (percutaneous endoscopic).

With a different device, use 0P9400Z (drainage device).
