About 0RHT05Z

0RHT05Z is the ICD-10-PCS code for a insertion procedure on the left carpometacarpal joint using an open approach with external fixation device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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 0RHL05Z (right elbow joint), 0RHM05Z (left elbow joint), 0RHN05Z (right wrist joint), 0RHP05Z (left wrist joint), 0RHQ05Z (right carpal joint), 0RHR05Z (left carpal joint) and 5 more.

The same procedure with a different approach is coded 0RHT35Z (percutaneous) and 0RHT45Z (percutaneous endoscopic).

With a different device, use 0RHT03Z (infusion device), 0RHT04Z (internal fixation device) and 0RHT08Z (spacer).

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.
