About 0RHT08Z

0RHT08Z is the ICD-10-PCS code for a insertion procedure on the left carpometacarpal joint using an open approach with spacer. 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 insertion or replacement of (cement) spacer, the ICD-9-CM procedure title it maps to (84.56).

For a different body part, codes include 0RH008Z (occipital-cervical joint), 0RH108Z (cervical vertebral joint), 0RH408Z (cervicothoracic vertebral joint), 0RH608Z (thoracic vertebral joint), 0RHA08Z (thoracolumbar vertebral joint), 0RHC08Z (right temporomandibular joint) and 18 more.

The same procedure with a different approach is coded 0RHT38Z (percutaneous) and 0RHT48Z (percutaneous endoscopic).

With a different device, use 0RHT03Z (infusion device), 0RHT04Z (internal fixation device) and 0RHT05Z (external fixation device).

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.
