About 0R9T0ZZ

0R9T0ZZ is the ICD-10-PCS code for a drainage procedure on the left carpometacarpal joint 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 arthrotomy, hand and finger, the ICD-9-CM procedure title it maps to (80.14).

For a different body part, codes include 0R900ZZ (occipital-cervical joint), 0R910ZZ (cervical vertebral joint), 0R930ZZ (cervical vertebral disc), 0R940ZZ (cervicothoracic vertebral joint), 0R950ZZ (cervicothoracic vertebral disc), 0R960ZZ (thoracic vertebral joint) and 22 more.

The same procedure with a different approach is coded 0R9T3ZZ (percutaneous) and 0R9T4ZZ (percutaneous endoscopic).

With a different device, use 0R9T00Z (drainage device).

It is an operating-room procedure in the MS-DRG logic for DRG 506 (Major Thumb or Joint Procedures) and DRG 906 (Hand Procedures for Injuries), under the surgical categories “Major Thumb or Joint Procedures” and “Hand Procedures for Injuries”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
