About 0P944ZZ

0P944ZZ is the ICD-10-PCS code for a drainage procedure on the thoracic vertebra using a percutaneous endoscopic 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).

For a different body part, codes include 0P904ZZ (sternum), 0P914ZZ (ribs, 1 to 2), 0P924ZZ (ribs, 3 or more), 0P934ZZ (cervical vertebra), 0P954ZZ (right scapula), 0P964ZZ (left scapula) and 20 more.

The same procedure with a different approach is coded 0P940ZZ (open) and 0P943ZZ (percutaneous).

With a different device, use 0P9440Z (drainage device).

It is an operating-room procedure in the MS-DRG logic for DRG 495 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with MCC), DRG 496 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC) and DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur without CC/MCC), under the surgical category “Local Excision and Removal of Internal Fixation Devices Except Hip and Femur”.
